Artificial reefs... The Use
of Electrical Current to Enhance Calcium Carbonate Formation – 08/02/07
Hello WWM!
<Hello Marc! Mich here!>
As always thank you for this wonderful website!
<As always, thank you for the kind words.>
Tonight, I have a question regarding artificial reefs. I saw a program on TV
this week about the Palms Islands off the coast of Dubai (United Arab Emirates).
I fear that this project might very well doom a huge part of the marine
biodiversity in this area, but that is not why I am writing. In this program
they spoke of their intentions on building a huge artificial reef around some of
the islands. They were using an interesting technique involving a metallic
structure in which an electric current is sent (I don't remember the intensity
of this electric current). This technique was supposed to attract "corals" to
the metallic structure, and thus, building a new reef.
<Yes have heard of this. More here:
http://news.bbc.co.uk/2/hi/technology/3717168.stm
http://www.globalcoral.org/Electric%20Reefs.htm
http://www.globalcoral.org/index.html>
What they showed resembled a lot calcium carbonate (they called it "live
corals", but I doubt there was any living corals on these).
<No, the corals are living.>
I tried finding more info on the web regarding this unique technique, but
haven't found any.
<It's out there, you just have to look.>
What do you think about this technique and do you have more info on it,
<It works. See links above>
specially regarding how it could "create" coral skeletons (my guess would be
that the electrical current enhances calcium carbonate precipitation)?
<Enhances Calcium Carbonate formation. Providing some of the skeletal material,
allows the coral polyps to focus its energy on tissue generation.>
Thank you for your time,
<Welcome. Mich>
Marc.
Re: Artificial reefs... The
Use of Electrical Current to Enhance Calcium – 08/02/07
Thank you very much for your answer Mich.
<You are quite welcome Marc!>
Haven't had time to read the three articles yet (just the first one), but it is
very interesting. I understand now that, while this technique does not produce
live corals, it promotes their calcification once they are grafted onto these
arks.
<Yes.>
I think the reason I didn't find more info on the subject is because I wasn't
searching with the right keywords
<This may well be.>
(the report I saw was in French and this is my first language),
<Oui.>
but now I know what to look for.
<Ahh, très bon !>
Have a nice day,
<Vous aussi! Mich>

Cyanoacrylate... to stick or not to stick... that is the question...
1/6/07
Hi folks.
<Hi there, Mich here.>
I wanted to buy some "reef glue" from GARF recently, but apparently they are out
and won't have more for some time.
<OK.>
My guess is that their product is simply a cyanoacrylate super glue gel that
they have custom labeled. I am wondering if there is a particular brand you
would feel comfortable recommending.
<Any cyanoacrylate is fine, though some people prefer the gels as opposed to the
liquids.>
Additionally, is it ever safe to use a cyanoacrylate gel to glue a soft coral,
such as a mushroom, to a rock until the shroom attaches itself?
<It's relatively safe, just not terribly effective.>
Or will that harm the mushroom?
<Should be OK. Usually they will produce a thick slime coat that protects them
and prevents sticking... a little counter productive>
I read something about the bonding/curing process putting off heat that actually
can damage or kill the critter.
<Yes is does produce a little heat, but most corals tolerate well.>
Don't want to do that. I am working way too hard to grow these, but sometimes
have a hard time getting them to attach, even using the bridal veil method.
<Yes often the attachment is the hardest part. A lower flow area with some
course shell/gravel substrate is often the best method to encourage attachment.>
Thank you!
<Welcome! -Mich>

You said "Any cyanoacrylate is fine"
Including "ETHYL" cyanoacrylate?
<Yes either methyl or ethyl cyanoacrylate should be fine.>
Bigger bottles is appealing to me. :) For all I know, this is the manufacturer
of the GARF glue.

Starting up a <Coral prop.> business 12/11/06
Hi Robert and/or Anthony,
<Mmm, Antoine hangs over at MarineDepot.com for pay>
Robert you have always answered my questions in the past, and I have books from
both of you. I and another partner are setting up a coral business. Currently
we are working with our LFS (at a very small scale),
<Good way to start...>
however, one of the mods of our reef club suggested we do more and involve the
members in terms of frag marketing to members as a club and possibly actively
having members as 'farmers' in a modified fashion.
<Has been tried...>
The goal would be to help bring high quality corals that are aquacultured
locally. I have been avidly reading Anthony's book on propagation. I have 20
acres of river bottom land here in the valley, but it gets hot in the summer for
about 2 months. I really like the idea of green house growing, but how do we
address the heat problem and electricity?
<There are cooling and shading mechanisms that can be brought into play...>
Also, are we better off going non-profit (paying ourselves hourly - we're not in
this to make big bucks) or commercial?
<Try upgrading your size/volume just a tad here and see how you like it... I'd
work out some sort of "business partnership" agreement twixt the parties... all
work about the same hours, tasks if possible... Split whatever is left...
quarterly or so... after electrical, something paid for rent...>
Who can we contact to purchase rare and unusual corals that are aquacultured
at wholesale prices to expand our production. Any suggestions would be greatly
appreciated.
Vicki Murray
<There are a few folks... You should "go the legal route" and quick like a bunny
get a fictitious name, business license registered... And contact Eric Cohen at
Sea Dwelling Creatures, Dave Palmer at Pacific Aqua Farms, Chris Buerner at
Quality Marine, Leonard Ong at Underwater World... All on 104th St. in L.A....
Their contact info. can be found on the Net, industry Buyer's Guides.
<Do you have the facility (physically) planned, built out yet? It might pay to
travel to LA... visit some of the above and other facilities, for ideas...
Bob Fenner>
Re: starting up a business 12/11/06
Robert,
Thank you. We have a license and a DBA name. I started it and have done
business with 2 of the companies you listed below.
<Ah, good... saves a good deal of time>
I have not brought on a partner yet. We are waiting until after the
first. Your, mmm... has been tried - means what?
<That I'm aware of similar relationships twixt start-ups of this sort and
club/members... always a concern that "the biz" and the hobby not be
taken/mistaken for each other... the former not seen/perceived as mercenary...
BobF>
thank you for the advise.
Vicki
Propagation Business 11/29/06
Dear Anthony,
<Mmm, no longer here. You might try him at Marine Depot (.com's) public site or
Reading Trees (.com)>
My name is Andrew Lewin. I am writing to you for some advice on starting and
successfully running a Coral and Fish Propagation Business.
<... I'll respond here for all though>
As a marine biologist and active hobbyist, I realize that there is a great
demand for aquarium marine life (I'm probably preaching to the choir!). My goal
for this business is to decrease the pressure on the reefs by successfully
propagating species in a laboratory environment.
There is a lot of information on propagation (I just ordered your book)
and fish breeding that I think that I can begin a successful business.
The business will distribute the species to retail stores, more consistent than
retail, in Canada (where I live) and then eventually the United States (speaking
with CITES on how to go about doing this).
<Hard to make "economic sense" out of direct sales to/through retailers...
"Economies of scale"... but can be done>
I have read most of the posts on your website regarding propagation businesses
where you mention that it would be good to offer some unique way of growing
corals or offer rare species that are in demand.
<Yes... as well as "standard" offerings>
Well, following this advice I want to experiment with the use of the Biorock
method. I'm not sure if you are familiar with this method, but the Global Coral
Reef Alliance uses it to restore reefs in the ocean. The method uses an
electric pulse (small enough not to harm animals) to attract minerals from the
sea water to a cathode. The electric pulse causes limestone to form on the
cathode providing a good base for coral growth. Corals tend to grow ten time
faster than normal. My question is: Do you think that this same process could
occur with artificial sea water?
<Mmm... only way to see is through experiment... Not likely economical... due to
the cost of electricity, time...>
If so, I could grow corals a lot faster and increase the turnover time of the
propagation.
<The ultrastructural differences here may be trouble...>
I have another question as well. I figure that the larger the business, I.e.
large number of corals being grown, the more money I would make because it would
bring my overhead costs down.
<Up to reasonable limits yes>
In your opinion, do you think that it would be wise to start a big operation,
more start up capital needed?
<I would start small-ish... boot-strap finance here... until you have a modicum
of practical experience... There are a few critical "realities" that exist,
you'll experience... For instance, the amount of time it takes to husband a
given sized operation... the incipient costs (opportunity costs of your time)...
and vagaries of dealing with folks in the trade, the airlines... You can/will
only "know" this/these through practical experience>
I was thinking of hiring staff, experienced in coral propagation and fish
breeding, to oversee the technical matters.
<... Unless you have a very large sum (a few six figures) to lose, I would NOT
go this route... not likely to be successful w/o your knowing first-hand what
needs to be done, doing "it">
Like I mentioned, it would require a large start-up cost but I would be able to
sell more product for cheaper (sort of like a Wal-Mart business model).
<... the markets for such an enterprise do not currently exist... or are
well-occupied by a few players (e.g. ORA...), that have "best-methods"
applications, honed-reduced costs of production... and still (IMO) relatively
low ROI models/results...>
I would like to become the largest marine species propagation business in the
world. It would be my part in saving the reefs.
I'm curious as to what you think about my idea.
Sincerely,
Andrew Lewin, M.Sc
<I encourage you instead to look into the history of Frank Baensch... & to set
up a model of producing, supplying rare/r species in a small setting here...
"Keeping your day job" at the same time for a year or two... I have many good
friends in the ornamental aquaculture industry... Many of these are tremendously
upbeat about this part of the industry's future (Carol Cozzi-Schmarr) of Ocean
Rider especially (am out on HI's Big Island currently). They've received
funding, are "trying" a few non-syngnathid species... Bob Fenner>
Re: Propagation Business 11/29/06
Dear Bob,
<Andrew>
Thank you for your reply and advice. I will follow your advice and start off by
slowly propagating corals and selling them to a local fish store as I improve on
my techniques and increase my ROI. Once I get a feel for the practice then I
will increase my production and research the fish breeding aspect of the
industry.
Thank you for your time. Your website is very informative and your books are
very good.
Sincerely,
Andrew Lewin, M.Sc.
<Thank you for this follow-up... And a further pledge/urging if you will. I will
gladly help you in what ways I may/can in this endeavour. I strongly encourage
you to get out, visit some such businesses... see the scale of their operations
(usually quite low-tech and not very business savvy... but many good folks just
the same). Do consider traveling about at times for trade shows, scientific and
hobbyist get-togethers that may well coincide with my travels. I will gladly
introduce you to the trade, people who may very well become instrumental,
influential in your dealings in the industry. Bob Fenner>
Galician Association of Aquariums ... looking for free coral prop. content
11/25/06
We sent this mail to them from the Galician Association of Aquariums, in
Spain, to ask for its collaboration.
Our main activity is to give information of techniques, experiences for the
maintenance of species in aquariums, thus we asked for some article to them to
publish in our page web, www.aga.lucus.org, on the propagation of corals in
aquarium and thus to be able as far as possible to avoid the abusive operation
that is becoming in reefs of everything by the world on the part of the
importers.

Gorilla Glue Reef Safe? 11/22/06
I searched the FAQs, but did not find the answer.
Forgive me if I overlooked it.
<No problems, thank you for looking before writing.>
And have a 72gal reef. For it, I have a 20g polyethylene drum that I plan to
store my makeup water in after it is processed by my RO/DI unit.
Unfortunately I have a continuous leak. I have attempted PVC glue and
silicone. With no success.
The two will not bond with the polyethylene. I tested super glue on the
surface, but it pealed off also. I tested Gorilla Glue, it pealed off of the
smooth surface but bonded fine with the test portion that have been sanded. My
questions is, is the Gorilla Glue safe to use? The Gorilla Glue Information
Pack, as distributed by the manufacturer, states it is non-toxic. I also looked
at the MSDS sheet. I would like to get a thumbs up or down from you guys! I
have linked (as opposed to attached to lighten you server load) the information
pack and MSDS below.
Thank you for your help!
Information pack as distributed my the company:

MSDS:
http://www.newpig.com/en_US/content/current/MSD-V288.pdf;jsessionid=3T2GYWVAQPUT2CTGIQVSFEQKMZCCWJVC
<Well, Duane, you're in luck. People have been using Gorilla Glue for ages for
coral frag placement and propagation purposes. Don't worry here, if it seals
your leak, you're good. However, if you run into a similar problem ultimately
with the Gorilla Glue, perhaps a 2 part epoxy, left to dry would work? Hope this
helps you! -JustinN>
Selling to wholesalers 9/26/06
I would like to propagate a fast growing coral species to sell to
wholesalers. If I were to reliably produce a relatively high volume of a single
species each month would there be a market for this product?
<Possibly>
If so, is there a comprehensive list of wholesalers to contact about their
interest in buying from a single species supplier.
<Mmm, not as far as I've ever seen... many can be found through searching about
in "Buyer's Guides"... produced by industry mag.s... Phone directories, you can
peruse at large/r libraries... searching the Net... e.g. organizations members
lists like OFI...>
Also, is there an industry standard as far as contacting wholesalers regarding
this situation (i.e., letter, phone call).
<Good question... Best to call them, ask who makes such decisions, what they
might be possibly interested in some/several months down the line... what they
might be willing to pay (FOB/landed) for such... But, allow me to cut to the
proverbial chase here and suggest you sell a mix of such possible cnidarians
more locally... likely the fish stores you can drive to will take about all you
can realistically produce... The nature of the trade is such that guessing "what
will be hot" and the margins being so small to non-existent dealing through
wholesalers, that you will first be most likely selling to LFSs, and second to
this, only/either to end-users/consumers... Not to both. BobF>
Thank you,

Transshipper - 09/07/06
Hi Guys,<Hey Lyndon, MacL here tonight>
A rather non-hobbyist question this time...<Sounds lovely>
2 of my buddies (1 in Sri Lanka & 1 in Bali) who own tropical marine fish &
coral (MAC certified )wholesale operations are pushing me to work as a
transhipper for them and to earn a cut out of it. I live in the UAE in Dubai
and am aiming at reaching the Middle East market to start and then if
feasible...expand...<Okay I'm with you so far.>
Id love to do something mutually beneficial for the 3 of us...Would just
like to have some ideas of where and how to start...<I think you'd need to
do some serious thinking and planning. For instance, how much of a
transshipper do you want to be? Would you need a place to store the fish for
short term or long term or would you just change the water and ship the fish
on to the next place? How much would the facility to do this cost? Would you
just have the fish go straight to the customer? What happens if the fish is
sick? Would you have any type of warranty? What happens if the shipment gets
lost somewhere in-between? It sounds like a good idea but I think its going
to involve a serious amount of work and a tremendous amount of time. Even
if you just set up a website where you listed the fish available and had
them shipped directly to the person wanting the fish there are many
complications to be thought through. I would advise you to talk to some other
transhippers. Perhaps attend a conference like MACNA where you could get
information and some valuable advice from people doing or who have done this
before. I will tell you I have a friend who started a new wholesale business
and is doing well at it but he's working 80 hours a week and has had many
many things go wrong. He says he would do it all over again but that he
might think things through much more thoroughly first. Hope this helps!>
Will building a web page for my operation help ? How do I advertise my
presence...<Web pages are good, local advertisements as well. I think also
face to face visits with your perspective clients is a good idea. Good luck
MacL>
Please assist...

Candycane skeleton disintegrating 8/22/06
Greeting from Nova Scotia
<Hello from San Diego, CA>
I have a small coral reef tank since 9 months that causes no troubles. One of
mine Candycanes got now about 11 branches (had 7 or 8
when we got it) and it's doing really good (dividing, long tentacles at night,
bright colours, etc...). Two days ago however, I noticed
that 2 of the branches are actually disintegrating. I am talking about the
skeleton at the back of the polyp, and surprisingly enough, the
polyps at the end of those branches are looking awesome and do not seems to be
bothered at all. I am suspecting a lack of Calcium and/or
the fact that my pH might be a bit too low (7.8/8.0)
<Could be more...>
so it drives the carbonate equilibrium of sea water toward the HCO3- side but I
am not sure. A friend of mine (has a big coral reef tank) said that it might
be the fact that my Candycane is submitted to water flow that are two high.
<Another factor>
I doubt it, but do you have any suggestions ?
Thanks so much in advance
Flavienne
<Mmm, the ultrastructure of the alkaline earth skeletal matrix is likely
"missing" something... happens frequently with (your as stated) imbalance of
calcium, magnesium and alkalinity... Do you have the "Kalk habit"? This is a
common situation (soft skeletons) with this use... other methods of supplying
ready alkaline earth, carbonate produce "harder" bio-matrix (calcium reactors,
two part supplements...). Bob Fenner>

Bases for Coral Frags - 8/15/2006
Hi,
What are your thoughts as to the suitability of oyster shells for coral frag
bases?
<<I have used them. While I prefer something with a rocky appearance, I did not
run into issues with the shells personally. Give it a try!>>
Seems to me they blend in much better in a tank than cement disks.

Advice needed on a small coral farm 7/6/06
Hi Bob,
<Matt>
I am currently planning to setup a small coral farm. I have limited space so I
intend to build a 3 high system, the bottom tank will be around 12 to 14 inches
high, and the other two will be 8 inches high. All of the tanks will be 4 by 2
feet. I am planning to use a design that is on the GARF site as well as their
system for maintenance and adding supplements (basically a mixture of SeaChem
supplements). Any advice for the maintenance would be greatly appreciated.
<Okay>
It is intended that the top tank will house 4 lights for soft corals, the middle
tank 6 lights for SPS corals and the bottom tank 3 lights for brood stock. The
lights will be standard 40w fluorescents. Is the lighting described sufficient?
<Mmm, no. There are a few things you can do here... add/allow some natural light
if this is possible... but if your intent is to "produce" frags in any
reasonable time frame, you will not want to limit photosynthesis by inadequate
lighting. If your local club has a "PAR meter" for loan, do measure the useful
lumens you can expect from this fixturing, at the water depths you'll have...
You'll want more light, both on the soft and stony corals>
Also would it be beneficial to have a substrate base for the grow-out tanks,
or should I install a rack for holding the cuttings?
<IMO/E it is best to have a calcareous-based material present... to proffer
alkaline earth material, bolster/sustain pH, aid in biological filtration... and
a few other ancillary purposes). This material need not be "in" the culture tank
per se, but remoted in sumps (I would keep the water systems for your SPS,
alcyonaceans separated>
Is it worth having high and low points within the shallow tanks so that the
coral may be closer or further away from the lights?
<Not really. Better to employ trays, egg-crate, whatever system of "stand offs",
supports you'll be using and just stick with these. There may be utility in
having different height "stand pipes" for regulating water level itself (to aid
in light penetration, improve circulation in the remaining/allowed volume).
These can/should be "sleeved" with a covering pipe that is notched at the
bottom, to facilitate moving water from the bottom...>
I intend to have a cleanup crew in the tanks to ensure that it is kept clean and
tidy.
<I would be careful re selection here>
I will have power heads which should provide enough water movement as well as a
skimmer, not sure which one yet!
<Keep asking about... many folks have and have tried to run "at home" small
culture facilities as you are seeking to do. Their experiences are valuable,
worth seeking... on the various "Reef" BB's like Reef Frontiers, Reefs.org,
ReefCentral...>
If there is any other advice you could give or maybe something that I might not
of thought about then that would be super.
Hope to hear from you soon,
Kind regards,
Matt Risby

Coral propagation book Anthony - 7/2/6
Hi Anthony,
I would like to buy your propagation book signed. How and where:) I am a true
lover of the reef. I have an art BA and a masters in Science
Education - and reefs are both. You can see both in action in my little 4
minute video "Reef Magic" by going to:
http://www.murrayproductions.org/other.html
<Neat!>
and clicking on hobbies. I should have called it "Mandarin Love" (last minute
shows its true beauty). I am very much a rooky, and I
bow to you guys who have gone through it all. You are the masters!!!
I want to start a propagation tank; I have an LFS who buys my xenias now and I
would like to produce more for him. Besides, my tank is
getting a bit crowded.
Vicki
<Have sent Antoine your note (he's off having other adventures elsewhere.

Re: coral propagation book Anthony - 7/2/6
Thank you Bob, I am amazed that with your experience and others, that you
are all so available online. Wow!

Leathers, SPS, DASystems 6/25/06 -
Friends at WWM,
<Scott>
I have two DAS units that I keep all my corals in. Each unit consists of two 75
gallon tanks and a 50 gallon sump. Both tanks are free of
fish all the time aside from the occasional oddball like an angler.
In unit #1 - Top tank has all our mushrooms and zoos - which thrive. The bottom
tank has only assorted leathers - of which 75% of them are
really thriving, and the other 25% have a few assorted issues which the primary
cause for this email. I believe that it's either aggression or some sort of
disease.
<Chemical...>
General symptoms include: a general failure to thrive, sloughing excessive
slime, dark rings of some sort constricting the "fingers", overall shrinkage in
size even when extended, darker
necrotic looking tissue on the tips of certain corals, a "splintering" at the
base of some corals, and stasis - never opening, closing, growing, shrinking, or
changing in any way shape or form. Bear in mind this is only 5 out of 20 or so
- Looking at few crown leathers and a couple of spaghetti-type leathers. We
don't run any chemical
filtration, aside from occasionally throwing in a bag of Purigen when things are
looking gnarly. We aggressively filter floss my water to help compensate for
the lack of an efficient skimmer. We don't change the water as often as we
should, but we probably cycle out 20% per month. None of the described corals
have ever thrived at any point in
our care, and have been around anywhere from 1-4 months. The other leathers do
amazing, showing great polyp extension and rapid growth.
In unit #2: I have a lot of LPS, mixed with a few SPS, and anything that isn't a
leather, mushroom, or zoo. The bottom tank has halides - and
virtually every "genera" of coral thrives well in that tank.
Occasionally random things don't do well here and there but overall I can pretty
safely put just about anything in there and expect it to do
well. Overall the whole unit maintains pristine water conditions and food
supply - even extremely picky/difficult to keep species have
thrived for extended periods of time in this particular tank (a feather star for
8 months running, a couple of ugly Gorgs for over a year, a
Flowerpot for 5 months running, et al. (I don't sell them to any average
customer, so they tend to sit around)). To the point - long
term my SPS don't thrive - and to date I've simply accepted that and avoided
them as much as possible. I chalk it up to inferior bulb
quality (Coralife HQI's, 20k) and insufficient calcium/alkalinity levels (though
I do excellent with clams?)
<Maybe>
- coupled with the fact that the tank is overcrowded with other aggressive
corals. So my question here is if I split things up between the top and the
bottom and gave SPS
their own tank (not their own system) and maintained chemical filtration what
are my odds of being able to keep SPS profitably?
<Can only try and see... but not great odds... see my note re DAS below>
And though you may already answered this - in a tank where everything does
amazing except SPS corals is there some other variable that would affect only
SPS longevity that I'm not accounting for?
<Likely just allelopathy mostly at play here>
As an interesting side note - around 6 months ago I switched us from a drip
acclimation to the old fashioned float/drop style acclimation.
Since making that conversion the survival rate of our corals within the first
three days of acclimation went from approximately 80% to over
95%. Now it would seem counter-intuitive to me that a more rapid fire
(/non-finesse) acclimation would yield better immediate results but
stunt things long term - but it's my job to wonder.
Thanks,
Scott
<Dutch Aquarium Systems went through a few revisions over the years they were in
production. I really liked their "craftsmanship" of the tanks, stands
themselves... but their mechanicals were largely less than sufficient. I
encourage you to bolster all these aspects... skimming, pumping, lighting,
chemical filtration. The SPS question... these corals by and large don't "play
well" with other cnidarians and as a general rule require higher quality, more
consistent water... Are best cultured on their own, or at least "first" placed
and other smaller colonies of less-noxious cnidarians added months after they've
become established. Bob Fenner>
Opinion on..... outdoor coral beds - 05/15/06
Bob we met at the Nextwave at our DFWMAS club in Irving Texas. I was very
impressed with your incredible first hand knowledge of the Marine aquaria
industry. Which is the reason for this email.
I live in Fort Worth but not in the city limits and have no restriction on the 4
acres where I live. There is a 2000 sq foot house also available. Seeing how
your from Cali I thought you might like the choice of name for my new
adventure......Ripple AquaSource...
<Heeee! Have had their wine on occasion...>
it's also one of my favorite songs by the "Dead"...the other one being Cassidy
which is my daughter name. My wedding song was Sugar Magnolia
<Seems reasonable>
I would love to ask you a few questions if that is possible, I do like the good
folks at Garth and there projects.
<The singer or GARF?>
The cool thing about this I plan to fund it with a gas lease I have. Funny story
lived here 21 years and out of the blue a guy shows up with a gas lease. too
funny. I do like the idea of funding this from some unexpected funds from
something underground to something underwater. thought about making a 400 foot
wall around the front of my place out of DIY live rock know where I can get my
hands on 20,000 or so pounds of crushed coral and oyster shells cheap??
<Mmm, yes... likely... Call around the "local" sand and gravel plants re... ask
them how much to deliver...>
I lost the link on the guy in Ohio that has done this if you know it please
forward...

Coral exporters 3/30/06
Hi Bob, sorry to bother you. I'm sure you probably won't remember me from
IMAC the last 3 years as you meet a lot of people there and are a popular person
at the bar afterwards. I've been at IMAC and MACNA the last few years with
FRAGExchange.com doing all the fragging demonstrations with Eric and Anthony and
now with Steven Pro this year as well.
<Ah, yes>
Anyway, I've been looking into importing coral and starting a small business
to start, my goal is a greenhouse, but that WILL come in time. I know with your
extensive travels in Hawaii, Fiji, Belize, Galapagos Islands, and on and on and
on. I was wondering if you could point me in some direction to some good
exporters of coral and fish as in Canada it is hard to get nice/healthy coral on
a regular basis.
<Mmm... well... for others notice here, you know that HI, Belize and the
Galapagos don't allow any Cnidarian biz... and... will state below>
I hope you don't mind me asking but I thought I would ask someone who would know
and may have possibly seen these operations in process first hand.
Thanks, Mike Hughes
Sea you at IMAC if you are there!
<Ahh... looking forward to this. I do hope I can make known to you more fully
with an in-person conversation there. The nature of the industry is such that I
encourage you to buy your "brood, or frag-stock" from intermediaries/wholesalers
at this junction... Unless and until you have a very large operation (perhaps a
few years hence), there is just no "sense" to buying or piggy-backing a
large-size (like a D-3) container... for the purposes you have in mind. Put
another way, you won't make enough money to make it worthwhile to import many
dozens of boxes, sufficient to get a discount on freight, customs, all the
hassle of putting stock away, keeping it alive long enough to frag, re-sell...
Instead, do consider buying a few boxes of specimens from good sources... like
Sea Dwelling Creatures, Pacific Aqua Farms, Quality Marine, Underwater World...
in Los Angeles. I know these folks/businesses to be honest and competent. Feel
free to direct questions, responses to me. Bob Fenner>
Please lend advice to a budding coral farmer 3/24/06
Hi Mr. Fenner,
<Niki>
I know you are so busy, thank you for all you do. My name is Niki, I have
actually spoken with you before on a couple of occasions. I have been working
for a retail saltwater store for a while, and recently I got 15,000 to start my
own business. not a whole lot, I know. My dream is to have a little place to
grow coral and then sell on the Internet.
<A worthy project>
I have good relationships with a lot of agents at ERI, ORA, etc. due to working
in the industry for a while. I am 23, but I am fairly confident in my knowledge.
I would love to have something like reefer madness or ultimatefrags. I love
the idea of Internet and not retail. Do you think it could be done with 15,000,
a 20ft x 30ft room and a lot of grit and determination? :) and passion for he
hobby?
<Yes. Of a certainty>
I would love to hear any input at all. If you think it would be a pipe dream or
if I would even make any money at all.
<Could be made to be profitable... with careful planning, the use of as many
"shortcuts" as you can find/make... Particularly issues of energy
use/consumption, scheduling your time/discipline, knowing and developing your
market niche... E.g., what species will you culture? How will you find, contact
your potential buyers? How to ship, process payments?>
I am going to go to bar tending school and work that as a second job so any
money that the farm pulls can go right back into it. I have Mr. Calfo's book,
it's been a big help. thank you in advance for even reading this.
Sincerely, Niki Englerth
<Much to consider here. One very worthwhile and telling experience is to "do a
business plan" with layout, costs to build, operate your proposed farm... AND a
spread sheet with time frame, showing what you expect to sell, the subsequent
profit... Go into this with your eyes open Niki... can be done, but... important
to realize the "opportunity costs"... that is, what you might otherwise do with
the same resource/s... particularly your time. Think on this well, and feel free
to write back. Bob Fenner>
Re: Coral Farming for profit and adventure
3/27/06
Hi Mr. Fenner - I wrote you not too long ago on my mini-coral farm
aspirations.
I thought very carefully on everything you said. It makes me very happy that
you think it could be profitable. I'm sure there are a million other people
trying to do the same thing I am doing right now, so I want to make sure I stand
out in the crowd.
My thoughts are as follows: My main focus will be Acros, other stonies, and
basically anything that is beautiful and rare. I also will have the staples, you
know.. Sarco's, common corallimorphs things of that nature. After thinking on
it, I am also going to try and breed clownfish, various shrimps and Banggai's.
My "niche" I suppose you can call it, is that I want to sell only 100%
aquacultured stock. I plan to sell at very affordable prices also. I don't
believe that I will make very much money in the start, but over time, I want to
build a nice base of repeat customers.
<Do "keep your eyes on the prize"... You need to be profitable... I would not
charge much less than "the going market">
I am going to be a quarantine-Nazi. I plan to do everything I can to research
new methods of propagation, and share them with my customers. What are your
thoughts on the combined shipping method of pricing? When the price is all
together? Do you think that is good for business, or could it shock people away?
<Mmm, there is this danger... better IMO to let folks decide for themselves how
they want to ship, pay for this>
Are there any things you can think of that should be done in these businesses,
that aren't? Can you think
of anything that you wish was done more, or better?
<Many, many aspects... but it is far more important that you discover this/these
on your own. One item: I do encourage you to offer some drygoods... products,
lines that you will be using yourself as well.>
Above all, I don't want to get ahead of myself. I am thinking to start just a
couple of Rubbermaid tubs, and several small aquariums for the shrimps and
clowns in the beginning. I have all the time in the world to devote to my
little business, how long will it take to get rolling in your opinion?
<Define "rolling"... a few to several months to initially set-up
entirely/functionally... a good two years before you have much "rolling
stock"... hopefully not too much time beyond this to be profitable>
I know it is a very general question, but I'm sure you have an idea.
I will not skimp on the website, for sure, I want it to be fantastic, and I
also want to advertise on WetWebMedia. How much does that usually run?
<Better at this juncture for you to sell us actual articles detailing your
progress, philosophy... with photos. This will help keep you on track, focused
and make a few dollars to boot>
And also, I was wondering if you think it might be a good idea to fly out to
L.A. and hop around and visit ERI
<... I would not deal with Rob Miller... a bad rep. in the trade... for good
reasons. As you might realize, this being the Net, I do not categorically mind
you/others repeating my opinion>
and all those places.
<Look to honest, professional sources instead... Quality Marine, Sea Dwelling
Creatures, All Seas Marine, Underwater World, Pacific Aqua Farms... there are
many other worthy dealers>
I was thinking it would be a good thing, because I would probably meet a lot of
wise people and I could see how top notch facilities are run.
<Yes. Worthwhile to see their set-ups for your design, construction... and
nothing better than "to press the flesh" in terms of securing, building business
relationships>
Once again, thank you so much. I have learned so much from you, and its so
cool that you answer all of your emails. - Niki

The big question polyp extension 01-08-06
Hi guys and thanks for a great site!!!!
<Hello and thank you.>
Here is my run down of my tank specs: Size 36x24x25
Lights 250 de Helios 12500 14 inches from water with two VHO 110watt actinics.
With 140 pounds of live rock
Two sea swirls connected to a sequence dart with not much head pressure
Precision marine calcium reactor
Salt 1.025
Calcium 380
Ph 8.4 - 8.25
Temp 79.5 - 78
Now everything seems to be doing great fish and coralline is doing well. Corals
are showing growth but there is not much polyp extension. There is tons of
extension at night it is crazy of the difference between night and day. I have
a milli that has nice fuzziness but not like it is at night. I have a plana Acro
table that has good ext at night, but occasionally puts them out in the
day. One of my Acros has never extended a polyp in the day.... Is the problem
that they are still acclimating because they are still pretty much 1.5 inch
frags? I have the dart dialed back a little should I raise the output a
little. I am guessing it probably has about 2000 gph with the head pressure and
all.
Is it bad for the coral to be occasionally passed over by the sea swirl with
direct force for a second or so? I do not want to rip the polyps of the coral
when flow hits them directly for a second or so. Because there seems to be a
lot of flow coming out of the outlet..... I hope I am not sounding paranoid
just new to SPS. Thanks so much and I hope I made sense with my question.
<You are witnessing nature and evolution at their finest. Your corals will
extend their polyps to feed at night because there is more food in the water
column at night. There is also a polyp protection factor to consider. At night
there is far less of a chance that a coral nipping fish will swim by and graze
on the coral's polyps. If you want to see their polyps during the day your will
need to start feeding your corals, during the day, this will make it worthwhile
for the coral to extend its polyps. Travis>
What Is Going On In My Tank? - 12/20/05
Hello Crew,
<<Howdy>>
Hope you are all well, glad to see the wealth of information is still growing.
<<By leaps and bounds.>>
I would very much like some help with regard to my reef aquarium.
<<I shall make an effort...>>
A run down on the set-up first.
- 300 gallon all glass 72x30x30
- 3 x 250 watt 14k, 2 x 140 watt actinics, 2 x 58 watt actinics
- Halides less than 6 months old
- Turnover 25,000 lph, plenty of laminar flow and turbulence
- pH night/day 8.0/8.2 a bit low I know
- Kalkwasser dripped nightly
- Aquamedic calcium reactor effluent pH 6.7 at 2 drops per second
- Reactor media currently ARM
- Calcium 400ppm
- dKH 11
- Salinity 1.025
- Phosphate '0' with Deltec/Merck test kit
- Nitrite 0
- Nitrate 0, can't seem to get this to even a few ppm
- Skimmer - Deltec AP850
- ORP 360+, ozonizer 100mg delivered through skimmer
- Strontium approx 9ppm
- Fish - 14 small to yellow tang size
- Corals - around 25, sps 60%, LPSs 40%
- Water changes - 15 gallons every 2 weeks
<<Should double this...at the least.>>
- Kent Marine 4 stage RO filter, TDS reads maximum of 3
- Kent Marine organics resin
- Feeding 1 cube of Artemia daily
<<If this is all you feed you are 'starving' your tank occupants>>
- SPS in corals top 1/2 of tank
- Rowaphos used continually in reactor
- Live rock around 150 kilos roughly
- 2-inch sand bed, fine sand
Now the problem of which I have been scratching my head for about 1 year over or
since set-up, so little hair left! Almost all corals are always pale, lack of
symbiotic algae I think,
<<Mmm...>>
sps always seem pale with little polyp extension, corals lack real growth, sps
corals seem to never base down properly receding from the base upwards,
coralline algae seems to grow to about 1 penny (1 cent) size and start to recede
from the center. There is just a real lack of vigor.
<<I see>>
I have a Stylophora which grows more like a birds nest coral, very thin the
upper branches show very little polyp extension although the parts in the shade
on the underside seem nice and rich in colour and extend much more.
<<Curious...I have a Stylophora that's just the opposite...colors up on the side
facing high intensity lighting.>>
I have a few Lobophyllia corals which seem pale also. Something is amiss and I
am very baffled. Do I need some big water changes?
<<Or maybe a change in salt mix.>>
Is the tank too clinical?
<<I don't believe so.>>
Do I need to up feeding?
<<Most definitely. Get away from the brine shrimp, or at least don't really on
it for more than a treat. Feed some variety... fine meaty foods like mysis
shrimp, chopped krill/clam/squid, Cyclop-Eeze, Sweetwater Plankton, a quality
pelleted/flake food, etc....a couple times a day if possible.>>
apart from the low pH,
<<Not an issue here.>>
the parameters and maintenance seem a great recipe for success, or is the '0'
nitrate a major factor?. Lost for ideas and after so long running out of
patience. I look forward to hearing from you soon.
Best regards,
Lee
<<Extremely low nitrate could be a factor. Increased feeding with better foods
will help...is essential in this case. EricR>>
Coral Coloration and Polyp Extension 12-12-05
Hi crew,
<Hello>
My problem is trying to understand why do some corals change colour and why
some do not open.
<The mystery of the reef.>
My test this week-end calcium 400, ph 8.4, ammonia 0, nitrite 0, nitrate
0.5, alkalinity 6, phosphate 0.1, magnesium waiting for new test kit, did
not have time to test light reading (PAR) but lights are 3 months old 2 *
14K T5 white and 1 * 20K T5 blue
for a 150cmL * 45cmW * 40cmH aquarium holding 230l water, water circulation
3300lph.
<Sounds good.>
Devils hand. (Lobophytum)
The devils hand expand fully but the polyps do not expand at all. I can only
see white dot on the fingers.
What does it take to have the polyps extended fully more circulation, lights
etc?
<You might have too much current, not enough current, or need to add a
supplemental food, such as live phytoplankton.>
Colourful soft corals e.g. pink and yellow colt (Cladiella) and finger
leather coral (Sinularia I think).
I have a number of pink and yellow colt and finger leather coral but over
time there colour begins to fade.
What is the requirement for them to maintain their bright colours, e.g.
stronger lights etc?
<Run carbon and do frequent water changes.>
Any information will be highly appreciated.
Thanks
Mo.
<Hope that helps, Travis>
Some Light Conversation (Light and Coral Growth)
- 10/24/05
Hi Anthony, it's Genaro Again can you please help me again.
<Hi Genaro- Scott F. in today. Anthony is pretty busy with some other projects at the moment; hope I may be of assistance...>
My tank dimensions are 48 x 15 x 18. I have been using one Mh14K Hamilton about 10 inches away from water but corals do not grow.
<Interesting that you are not experiencing any growth. I was just having a similar conversation with another WWM crew member on a similar topic. Most metal halide bulbs of this spectrum should produce SOME coral growth if positioned in this proximity in a tank of the depth you're describing. Perhaps you could move them in closer (Say, 8 inches to start). Also, I'm assuming that you're growing corals that enjoy higher light intensities. Yes, different spectra provide
different results, so if you're completely unsatisfied, you may want to consider a different bulb as well. Other things to think about: Water clarity, competition from other corals, water flow, nutrition, and environmental parameters (alkalinity, pH, calcium, etc.). Lots to think of.>
I do have a 660 icecap to add two 110 watts VHO. Can you tell me which of the VHO will be better Aquasun,50-50 or
Super Actinic.
<They are all nice bulbs, IMO. However, if you're looking for optimum growth, I'd be inclined to go with the "daylight" or "full spectrum" bulbs, unless you're working with corals that thrive under bluer spectrum light. Actinics are great for aesthetics, of course.>
And, how long on the hours.
<I'd run them at least as long as you run the halide. Lots of people like a "dawn/dusk cycle, using the VHO actinics before and after the halides come on/off for this effect, although it is not necessary, IMO.>
Thank you again Genaro.

Hello Bob,
<Todd>
My name is Todd Melman and my companies name is Reef Systems in New
Albany Ohio. I have done business with your wife with Knop I believe...
<Diana? Yes>
Hopefully I have things straight and not crossing names... Anyways I am
building a coral farm here in central Ohio near Columbus and I am at the
final ends to this year long project, actually over 3 years but whose
counting. My questions are concerning several things pertaining to my
greenhouse. I was wondering if you had any good suggestions or DIY plans on
building concrete vats out of cinderblocks.?
<Mmm, it's been a while... there are "standard works" on such things...
likely can be borrowed from a larger library, or purchased on the Net... re
concrete work, retaining walls... But I encourage you to consider other
building media... plywood and two (perhaps some four) bys, carriage bolts
and liners ala Dick Perrin, Tropicorium... Gel-coated fiberglass like our
ready koi ponds in the last series of retail stores we knocked out... Totes,
Rubbermaid Troughs, pre-made aquaculture tanks... even thick glass and
silicone, ala Calfo, if you can get this cheap locally>
I am looking for hydrostatic pressure formulas or anything pertaining to vat
construction etc. Also I am having concerns on heating situations and with
not knowing where to really focus.
<... after three years? I would look mainly into passive methods, then heat
pumps... you don't want to pay (much) for heating...>
Should I be more concerned with maintaining my grow out vats temperatures ?
or try to maintain ambient room temperatures to maintain vats?
<The water temp. is all that's really important... what-whichever way it's
controlled>
I guess ultimately I was wondering if it would be possible to get in
contact with you over the phone to run some questions by you and pick your
brain.
<Mmm, would rather not... am over in Hawai'i currently, busy>
I believe we spoke a little over 2 years ago via the phone and as I
remember you were very helpful with some of my questions at that time. Also
I was planning on trying to get in touch with Anthony Calfo, do you have a
contact email for him?
<Will Bcc him here>
I know he is someone else in the hobby/industry who is willing to divulge
information. Just looking for a little help with my 13 years in the planning
dream..
Thank you for your time...

Re: Building CORAL FARM/looking for some help 10/20/05
Thank you for quick reply Bob...
<Welcome>
Why do you discourage the use of cinder block vats for grow out
containers?
The containers I am looking to build are going to be around 1500-2000
gallons each with around 10 to 12 total. I am looking at sizes ranging
from 12-14ft long by 5ft wide by 40" in depth.
<... why this depth? For culture, you want a minimum of water distance twixt
the animals... if you raise them up... is there a need/desire for this much
space under? I would raise the containers to facilitate working in/on them
myself... The concrete, blocks cannot be moved...>
Even if I were to build these containers out of plywood and EPDM liner my
cost into each container is going to be close to the same either way.
Fiberglass or polyproethelen sp? or some other plastic containers out there
are just too costly.. I think the cost of building the concrete cinder block
tanks are going to run me about 700.00 in cost compared to custom plastic
tanks costing me around 3500.00 each...
<Look into much shallower ones... making supports underneath... much
cheaper>
So what are your concerns with the concrete tanks? I have been to
Tropicorium many, many times, what true reefer has not? The problem is that
he often needs to repair or tear down containers to fix them do to leaks.
<Dick uses polyethylene, Visqueen... junk... Look into at least 20 mil PVC,
Butyl... much stronger, longer lasting>
I really want to avoid that considering the time and energy wasted in the
repair. And the potential loss of life do to "Low Tide" The look of
plywood tanks as well with the bowing of the tanks are making me sway away
from them. Any other comments would be appreciated..

Cyano encroachment on coral growth (Correct the problem not the symptoms)
10/9/05
Good morning
<Hello Lucas Adam J with you. It’s Late at night now.>
I received a colony of these polyps from a friend. When I received them they were all ready in decline. The colony only opens up about 5-10
polyps a day but there is Cyano and green hair algae building on them.
<Algae encroachment on coral is usually a sign of a few things: Not enough water flow, to many dissolved organics (nutrients), or perhaps inappropriate lighting (not intense enough, wrong spectrum, or old bulbs even).>
If I clean them gently with a soft tooth brush the purple coating comes off, I would really like to save these if I can. Will cleaning the
algae off removing the purple colored coating kill them off?
<This is a common practice and if done carefully is fairly easy. Employing the use of a turkey baster to gently blow off the algae is a good alternative if the toothbrush scares you. The algae should be fairly easy to remove without damage to the infrastructure of the colony (the purple “stuff” they are residing in). Having said that if you do not correct the problem that is feeding the algae growth it will return.>
Thanks again...Lucas in Denver

Help with coral growth 9/29/05
Love the website. <Thank you> I just started a reef tank, about 2 months
ago, and have
done so very slowly trying not to make any mistakes. <Patience is a virtue in
this hobby.> I have basically setup
my tank to what WWM suggest and things are great so far. I have a 37 gallon
with about 650gph of water filtration, 40 pounds of LR/LS with just two
damsels and no corals for now. In my sump/refugium I have a micron sock,
bio-balls, Euro-Reef CS5-3 skimmer, and 10 pounds of miracle mud. Now the
next thing is deciding what to put in with the miracle mud. I want to focus
on coral growth perhaps SPS, once I get the beginner corals mastered.<Mushrooms
are a good beginners coral.> You
have stated that Caulerpa will take away from coral growth. <First time I've
heard this. In my opinion it actually helps growth as microorganisms are
produced from the miracle mud and serve as a food source for the corals. Keep
in mind corals do produce most of their own food under proper lighting.> As far
as the
fish, the damsels will soon go back to the LFS and would like to buy a purple
tang,<Tank is much too small for keeping tangs.> mandarin dragnet,<An easy fish
to keep provided you have a continual live food source such as copepods. Very
few mandarins will take prepared foods.> false percula clown, and maybe one more
goby or
something of that nature. So what do you recommend to put in with the mud
that will benefit the corals the best with growth and food (zooplankton) and
help the best with filtration and where to get the material (if it is sea
grass)? <Caulerpa work well. Check out Drsfostersmith.com, they sell various
algaes for that purpose. The algaes do help lower nitrates/phosphates.> Also
is the compatibility of the fish ok? Or could you give me a
good combination with the purple tang as one of fish. <The compatibility is
fine, but as I said, the tank is much too small for keeping tangs. Google
search the WWM, keyword, "tangs".>
Thanks so much for the time. <You're welcome. James (Salty Dog)>

Coral farm in Manado <N.E. Sulawesi, Indo.> 8/18/05

<Perry>
Have a customer in Singapore who has a collecting station in Manado.
They are thinking of propagating corals in the waters around their property.
But they have no idea how to get the farm started.
<Mmm, I know of a few fellows that could help them...>
Have you got any plans to visit Manado anytime soon?
<Di and I are hauling out through there (to Lembah... on the east side,
Bitung) sometime in December... on an inaugural cruise with the Aggressor
Fleet... new liveaboard there>
Maybe they can pay you for the advice.

<Am going to cc Anthony Calfo, Eric Russell, and can't find Richard Ross
(Antoine please fwd) here... in the hopes of their chiming in, offering
their services, leads to other folks. Bob Fenner>
Re: Coral farm in Manado 8/20/05
Hiya Bob...Perry,
I'm willing to help where I can, but admittedly, my coral farming experience
is pretty much limited to frag propagation at the hobbyist level. I would
definitely have to defer to Anthony on this. But that said, I'm more than
happy to serve as a sounding board, proffer opinions/ideas, etc....
I have contacted a friend on the retail side who has had contact
with/ordered stock from an operation in Surabaya that is doing this same
sort of farming/propagation in "wild" waters. If he is willing to give up
the name I will gladly forward...though I don't know how willing they will
be to assist a competitor.
Be chatting,

Thanks for the help.
Let me introduce you to Lek of Sentosa Marine. Maybe you can visit his
facility in Manado in December. Lek, Bob is a good friend of mine and is
very involved in the trade. Hope you guys can meet up in Manado and bring him
diving at the least dived spots at Nain that you mentioned.

Fragmentations 7/31/05
Dear Bob,
<Keith>
I just recently found your web site, and have been reading through many... many
of the FAQ's. I have a few questions of my own I hope you will be able to
answer. Before that, I will describe my current system (running for 5 years now
but I have had a reef tank for 12 years now). I have the following system:
a.. 240 gallon (all Glass Tank) - predrilled in rear corners for water flow
to/from wet dry
<Ooof! Please don't call me if and when it's moving time!>
b.. 2 400W 20k metal halides
c.. 4 6' VHO's (IceCap 660)
d.. Venturi Skimmer (can't remember the mfg. but it is about 2 feet tall)
e.. 60 gallon wet-dry (I currently only have live rock in sump with some
carbon bags - no other bio media)
f.. Aquatic Lifestyle Systems CR-250 calcium reactor
g.. IWAKI power head (22.4 gallons/min)
h.. 1 sea swirl (center of tank)
I.. 24gal/day RO unit (this fills a 100 gallon mixing tank in the basement and
also tops off my wet-dry sump (I have it dialed in using needle valves)
j.. 200 LBS of live rock
k.. 38 types of corals (mainly LPS and SPS)
Other nice features include plumbing from my sump directly to a drain tub in the
basement and my 100 gallon mixing tank. this makes water changes a snap and
ensures I never have a overflow problem in my living room.
Over the past 5 years I have slowing added functionality to my tank to make it
more maintenance free (or at least to a level that makes me happy). I am at a
point now where I am taking large coral fragments every month to the local reef
shop for credit. I have been thinking about creating 2 or 3 400gallons
propagation tanks in the basement to harvest and sell corals. I did read your
articles on this subject and was wondering what you though about a web based
business of coral fragmentation.
<I have a few friends that have/operate these... have built out such facilities>
I have not put a business plan together yet but plan to very soon.
<Ah, good>
On another subject, I have read about the refugiums and was wondering what
benefits it would provide over my current system. I have seen these systems at
the local store on the display tanks and do not see a great difference between
their corals and my own. Could you please provide me with some more detail on
these systems and any recommendations you might have.
<Mmm, this is all posted on WWM... a worthwhile addition to what you have, the
propagation tanks you may add...>
Finally, I would like to know what I could do to promote better base growth of
my SPS. They grow quite well currently but only seem to produce minimal bases to
support their structure.
<Provide slightly excess calcium, magnesium (check on the relative proportion
here) and alkaline earth minerals... "melt down" (in your reactor) proper
matter...>
All my Acroporas are thick and show signs of rapid growth on the branches but
not at the base. I am worried that if I try to fragment these particular corals
they may not produce adequate platforms from which to grow.
<This does happen... a valid concern>
I have learned that improper CO2 flow from my calcium reactor can stunt their
growth and cause excessive algae growth as well as improper lighting & water
flow.
<Yes>
Any information would be appreciated.
P.S. I primarily fragment out the following rapidly growing corals: Frogspawns,
Hammers, trumpets, torch corals, horn coral, pineapple corals, cactus corals,
birds nest coral, Pocillopora damicornis, and Staghorn Acropora (only for my
tank right now).
<Look into some high selling, fast growing varieties of alcyonaceans for your
new facilities... lordhowensis for your existing... Oculinids if you have
room... make adjustable trays in/for the new tanks, so you can have the colonies
near/er the surface... make a deal with your utility company to run your lights
at night... Bob Fenner>
Building a second coral farm 7/29/05
Hi all,
My name is Russ; I own a company in the U.K. called Atlantis Aquatics along
with my business partner Glyn.
We are moving to a garden centre over the next few months and I will be
building my second coral farm. My first attempt is in my garage and lit by
M/H and filtered with L/R and a large skimmer. There is currently about 500
U.K. Galls in the system.
I have a few questions aimed at Anthony, but any help would be gratefully
received.
My method of lighting will be natural; I’ve got various ways of cooling,
filtering etc but am confused about the material used for a Polly tunnel.
I’ve read Anthony’s book and did have 2 copies but alas they are now on my
missing list. (lent out and not returned). I remember that a certain type of
plastic was used to filter U.V. in naturally lit systems but I’m not sure
what thickness or material was used?
Our intention is to open the facility to the general public once complete as
there are none in the U.K. that I’m aware for people to gain knowledge.
Also, I’ve visited various garden centres in the winter and found these
tunnels to be very cold. Is there a way to insulate the tanks used other
than the usual methods? To heat the room itself will be very expensive to
setup and run in this country, along with the fact that our winters are very
long.
Thanks for your time in advance,
Regards,
Russ

Problems Attaching Sinularia - 06/11/05
Hi There, I was hoping you wouldn't mind answering a quick question about
Sinularia.
<<Not at all.>>
I have read the Coral Propagation Book (fantastic by the way) <<Agreed!>>, and
have tried just about every method of grafting (green) Sinularia I can
find. The frags never die, they just pull off and float away. some of these
frags have been attached 4-5 times by different methods up to 2 months from when
they were cut from the parent colony.
<<Yes...one of the more difficult corals to reattach to a substrate.>>
Here's a break down of the methods used. Natural Settlement: after 4 weeks
frags are still sitting in place but not attached.
Toothpick: after a few days tissue rips off the toothpick.
<<Too much water movement?>>
Superglue: Doesn't stick to the tissue at all and if it does the coral peels
itself off after a day or so.
<<Pretty much useless for this particular application, yes.>>
Wedge in drilled hole: black tissue forms at the hole and frag breaks away.
<<Yikes>>
Rubber band: compresses tissue too much - necrosis - no attachment.
<<Have experienced same.>>
It may sound like the current is too strong, but I have tried very low current
as well. I am fairly sure current is not the cause.
Hmm...too much water flow would have been my first guess too.>>
What we are using for substrate is small blobs of concrete that are cured in
water for 4 weeks. Could the concrete be the problem?
<<Is possible. If not fully cured, the high pH of the substrate may be
irritating the coral and keeping it from attaching.>>
Would the coral prefer a smoother surface such as river pebble?
<<Wouldn't use this...stick to a "marine" source.>>
Or is there something else about this substrate that the coral is rejecting?
<<As previously stated.>>
Sarco's love the blobs and attach within a week.
<<Different corals may/will react in different manners.>>
I have about twenty good healthy parent colonies that are crying out to be
farmed but until I crack the method I cannot see the point in going ahead.
<<Try this...obtain some cured live rock rubble, and using a sewing needle and
fine monofilament fishing line, "sew" the frags (securely but gently) to the
live rock. Place in a shallow container and put the container in your prop
system where it will receive "light" current. It may take some experimentation
on your part to find the right amount of "sewing" needed to do the job. Once
the coral attaches, cut and remove the mono.>>
Thanks for all your great work, Greg
<<Hope this helps. Regards, Eric R.>>
Info on Growing Coral for Reef Restoration
Hi,
I am looking for information about growing coral in labs to have it eventually transplanted back on the ocean for reef recovery? Do you know where I can find information about this?
<Mmm, there are plenty of such schemes, folks involved in such plans, only a few actually doing something re. Walt Smith is one of these latter>
Do you have anyone on your website in the academic community that may know about reef
restoration?
<Mmm, likely Anthony Calfo is a good place to ask here>
Thank you for your help.
~Melody White
<Will Bcc both in hopes they will contact you. Bob Fenner>
<<See
Google search here. Look for CORL (Coalition Of Reef Lovers), a non-prof.
organization that supplies areas in need with concrete "cages" upon
which to grow corals. They use coral plugs from the area, not lab-grown
specimens. Also, ArtificialReefs.org, makes "reefballs".
The AMDA is another avenue of exploration. Marina >> Re: Info on Lab-grown Coral
for Reef Restoration
Cheers,
Melody yes, indeed. I do recall several folks doing such work - although to date it has fared somewhat poorly
overall. To be specific, lab grown corals reintroduced have done only mediocre, while simple in situ fragging
and direct placement on the reef has fared much better (simply due to better acclimation/less stress to
divisions taken from the reef to the reef... versus duress for light/flow changes imposed on aquacultured
stocks).
As Bob has mentioned... its been done in Fiji. Also by the Nancy or Monaco Aquarium(s) as I recall. A
Caribbean effort has been done the same. And some minor efforts elsewhere in the South Pacific.
More successfully (and speaking to the in situ fragging) are the efforts of Todd Barber, John
Walsch, et al with the Reef Ball foundation. Do google them... fabulous success, albeit unusual structures.
Please feel welcome to call me at home if I can be of any assistance. I'm off to Tonga next week, but am happy to chat
before or after if you like.
Kindly,
Anthony How to ship corals
How do I ship live coral? Where do I get the supplies to do this? I got a butt load of pulsing xenia that I want to get rid of. I feel
terrible for throwing it away (which I don't) and I rather see it in a good home.
< Good question. I'm not the most frequent shipper but hopefully I can help. Currently many people are using these small little thermos type containers. I think you can find them at
Wal-Mart and they are typically Campbell's soup containers. Another option is a plastic bottle (like a
Gatorade bottle). A bottle like this is best then placed in a Styrofoam box (Calfo uses wine bottle cooler boxes). That is basically it. Especially for xenia. Some
SPS corals do much better when bagged floating upside down in the bag (attached to a piece of
Styrofoam). Otherwise as long as you are quickly (overnight) shipping you should be fine. >
Thanks,
Patrick

DSB info for coral propagation 3/16/05
Hello, I have enjoyed reading many of your informative articles in the past and hope that perhaps you can help shine a light on a number of questions that I have.
<glad to do so :)>
I am attempting to start a greenhouse grown coral farm. I have a number of personal tanks in which I have used DSBs to assist in environmental filtration. Presently I am setting up a 800 gal system and am investigating other sources for sand to use in these systems. I can purchase aquatic sand from my sources but have been reading
a lot of literature that says if you are not buying "live" sand, you are over paying for
basically playground sand.
<not true... there is no need for so-called "live sand". Its not needed, and frankly... many of the products sold as "live sand" are really a joke. Carbonate sand is carbonate sand... period>
I am concerned about this as I am not able to set the system twice but I have no need to spend unnecessary $. Hard enough to get started as a small business.
<no worries... clean, dry sand is fine or better: can be inoculated as you wish. More control>
If these substrates are indeed avail for proper use in these systems what do you
recommend? I have inquired as to available sands and have the opportunity to purchase many types.
<calcite or aragonite would be ideal. If you go for silica based sands... you need to compensate for its lack of buffer>
I have heard the "play sand " available at many home improvement stores works well.
<true... do see the many message boards posts confirming this through the years>
I also wondered about something like masonry sand.
<eh... rather dirty. Some concern for contaminants (river dredged)>
I know that they use this type of sand for playgrounds. It has a sugar sand particulate size. Any
recommendations would be appreciated. One further question, I have a great number of snails in my systems that lay eggs , but never does the population increase.
<some species have complicated larval cycles that do not succeed in aquaria>
Any ideas?
<do try for strombid snails from IPSF.com or Ceriths/cerithium species from Florida for easy to breed marine snails>
Thanks for your time and I look forward to your reply.
<best of luck in your endeavors :) Anthony>
A Budding Coral Farmer
Hello Mr. Scott.
<Scott here, Captain! (I couldn't resist that one!>
I would like to start my own little coral frag colony in my nano tank!!! How do
I start doing that? Do I break some pieces off my corals I have now and glue
them on a some live rock? Or is there some other way? Thanks for your time
<You're entering one of the most enjoyable (and responsible) parts of the hobby-
captive propagation of corals! Depending upon the species that you are working
with, it may be as easy as slicing off a section of coral and letting it settle
out on rock rubble (as in the case of soft coral), or using a dissecting shear
to cut some branches off of an established colony and supergluing them to pieces
of rock for grow out. To be honest with you, it's too difficult to generalize.
Lots of ways to accomplish this! I'd start by arming myself with Anthony Calfo's
"Book of Coral Propagation", which is packed full of information and ideas for
the intrepid coral farmer. Check it out! Good luck on your adventure! Regards,
Scott F.>
Not quite ready for the pet-fish biz
Bob,
<Ron>
I have been keeping marine fish for almost 18 years. I was 12 years old when
I set up my first saltwater tank after saving my paper route money and
Christmas money. I received my B.S. in Zoology with intentions of moving on
to graduate school for marine biology. Instead, I have been side-tracked the
past few years working as a chemist. I bought a new house a few months ago
and intend to finish the basement. Part of the basement is going to be
sectioned off into a fish room. My question then, is there grant money
available for such ventures and where would I look?
<Grant money... for? Building a fish room in your basement?>
Also, what is the best
way to go about having at least a part time income, e.g. research, breeding
and selling, etc.?
<Mmm, a bunch of things to relate here... First off, please do take a read
through our aquatic business subweb:
http://www.wetwebmedia.com/AqBizSubWebIndex/Biz%20Index/Biz%20index.htm>
I enjoy your web page and receive a lot of insight from
your answers. Thank you for your time.
Sincerely,
Ron Looker
<There are a few avenues you might take... production of rarer cnidarians...
Pacific Ricordeas (enhanced by cutting through siphonoglyphs)...
Cespitularias... oculinids... You need to research your local market to gauge
what might sell... and how much... to find if you're going to need to ship-out
principally... There is a bunch more money to be made with far less time, hassle
actually manufacturing a few well-placed aquatic chemical prep.s... or becoming
a regional distributor of an import line... Bob Fenner>
Coral Farming questions 1/4/05
I perused what I believe to be most of the FAQs on the WWM site, and didn't
find too much not of the retail/service side of the business. I was
specifically looking for more information about Mr. Calfo's previous business.
If I am just another schmuck who did not find the site for all the answers to my
questions, I am sorry for stupid questions. Else could you please point me in
the right direction?
<no worries... here in your service>
Such things as why'd he quit?
<many reasons, not the least of which was a desire to travel, write books and
spend more time photographing.>
How much was he making at his peak?
<working only four days per week (wanting to always spend more time with family,
versus 5 or 6 day work weeks), I netted over 100K annually with a profit margin
that peaked around 52%>
How many employees did he have if any?
<a one man band only>
How many square feet?
<1000>
How long did it take to make ANY profit (I read in the FAQs a couple years, but
I'm just curious)?
<exactly that>
How many gallons were his systems?
<8,000 on the high end>
Greenhouse construction (I've been reading, but most books focus only on
plants)?
<do check out the references in the back of the "Coral Propagation" book... it's
what they are there for my friend: where I bought sand, salt, greenhouse
supplies, etc. For starters, you can try XS Smith for GH structures.../ and
places like atlasgreenhouse.com>
I am soon to be finishing my undergrad and will probably shoot for earning an Ms
in Mariculture.
<you'd be better off getting a business degree, mate (seriously). But at any
rate, please do take some business courses and be sure to complete a thorough
business plan before making any fiscal move. There is great software out there
to help you like Business Plan Pro>
As of now a coral farm/import business is my dream,
and has been growing for around 4 years now.
<forget about importing as a long term option... you cannot rely on a living
from it in the 10 year plan if even the 5 year plan. Focus on farming corals
wholly... better profits, better for the environment, and more control over your
project/income>
Thank you very much for your time. Adam Beem
<best of luck and life to you, Adam. Please feel welcome to share your completed
business plan with me for a shared opinion. Anthony>
Acropora Color Change
Bob:
<Scott F. in today!>
I purchased some colorful Acroporas and placed them in my tank. In a couple of
weeks, they started to turn all brown. I have since got my phosphates to 0% and
my nitrates to under 5%. The acros are starting to grow with tips being
colorful. My question is will the entire Acropora return to its original color
now that I have my water quality under control?
Joey
<Great question, Joey. The prevailing wisdom is that the colors of coral are a
sort of natural "sunscreen", which the coral will manufacture as it needs them.
Under intense light and high water quality, it is certainly possible that the
colors will return to something approaching their original splendor. Phosphates
are well known to inhibit calcification and color in stony corals, so you were
right on in trying to get water quality in order. Interestingly, you will often
get different colors for the same species even under different lights. Good
luck! Regards, Scott F>
Strange growths in reef
Hello:
I have an 80 gallon reef aquarium that is about 8-9 months old. It had been
doing fine until lately when, about two weeks ago, this white fluffy and
stringy stuff started growing all over. It is even growing on the snails.
I have a plenum, five maxi jets, 400 watts of light, a protein skimmer and a
charcoal filter. I use SeaChem additives. As all of this is happening, my
coral have stopped opening and seem very unhappy.
WHAT IS HAPPENING??
Jill Bryant
>>>Hey Jill,
Are you using tap water by any chance? I've seen strange things happen with tap
water. Do you have a pic? If so you can email it to me here XXXX@target.com
Have you tested your water? What is the calcium at? Are you sure you're not
seeing mucus strings from tube dwelling snails? What additives exactly are you
using?
If what you're witnessing is in fact related to what you're seeing in the
corals, then it's a water quality issue. Make sure you're NOT using tap water to
top off or do water changes. Check calcium and alk.
I would start by doing a large water change using RO or natural sea water.
Eliminate your variables one by one. Drop me a line back if you have further
info/questions.
Good luck
Jim<<<
New Coral Growth Questions
Hi WWM crew. :-)
<Hello! Ryan Bowen with you today>
I have 2 questions regarding 2 corals that an online friend
mailed to me as a gift. <Wow! Nice friend> I was totally ecstatic over the
arrival of a fairly
sizeable colony of brilliant green star polyps and a small but packed to the
gills colony of yellow button polyps. I have had these things for not quite
a month now. <Great!>
I noticed some purply white, knobby looking mass starting to
grow out from some branches of the GSP's, and the consensus from my fish
group on Yahoo! is that this is the skin growing before the polyps form. <Yes,
an encrusting mat.> I
have found some evidence of polyps in the making like small bumps on this
new healthy tissue as well as other polyps. I noticed this evening when the
lights were out that there are several other spots where the skin is
expanding. My question is if when the polyps are fully open, I can't see
this new growth, if this stuff is branching out over existing healthy
polyps, does it just continue to branch out or encrust what is already
there? <Both, it will be like a weed in time! These are the easiest corals to
prop, and you can easily cut these up and spread them throughout your group.> I
have another spot that already has a skin and it looks like a
flower patch coming out of nowhere lately on part of the same rock. It's
already starting to form new branches. <Great! Signs of a healthy environment.>
Secondly, I have noticed that it seems like every time I turn
around there are new polyps budding on the button polyps. I saw a new one
today that looks about maybe 1-2 weeks old (from casual observation) that I
just discovered today. When these things bud from the foot naturally, if
there really is not enough room there do the others just move to compensate
for the space? <Yes, they will arrange themselves to their liking.> The colony
is not even golf ball size but well packed (30-50
polyps I guess). I would say I have at least 5 new polyps in the past few
weeks that have a mouth and crown. I have one I have been watching for the
past 2 weeks maybe (if that) and it appears to have a new bud coming from
its base!
I am not complaining about the growth, I am thrilled to see this
sort of growth. I just don't understand how these things compensate for the
lack of space and manage to survive. <Constant war. I'd suggest you pick up the
Blue Planet special on reefs- The constant battle for space is well
documented! Good luck, Ryan>
Thanks in advance (again) :-)

Calcium for LPS - 4/30/04
As you have been told a million times before, WWM is the BOMB <Da BOMB> and there'd be a lot more fish in heaven were it not for your sagely advice. Thanks! <Our pleasure>
I have a 75 gallon with a 30 gallon DSB sump that is nearly a year old. The tank consists of several reef safe fish (clown, fire fish, coral beauty, gobies and a tang), as well as several polyp types (sea mat, glove polyp) and a soft coral (have never been able to identify it, but it looks like polyps, bright golden-white in color but with 12 petals instead of the usual 8 on each polyp - the petals look like little round white nubs), and a candy cane coral that was recently added. I also have about 85 lbs of really good live rock and
a lot of macro algae growth in the sump (looks like hacksaw blades), <Caulerpa serrulata> the tang doesn't touch it <Won't touch most
Caulerpas as they are usually quite toxic>
I do weekly water changes of 5 to 10 gallons using RO/DI water, my parameters are perfect, the fish are doing great and the polyps and soft coral seem to be growing and doing well. Somehow, when
acquiring the candy cane, I didn't make the connection that this is a stony coral. <Large Polyp Stony coral or LPS>
I do not have a CA reactor. <Don't need one per se. If you had a many LPS or SPS then maybe>
The candy cane seems to be much happier in my living room than it was in the LFS (better lighting in my tank), <I am sure it is happier>
.. but I want to continue to ensure its happiness.<Good methodology>
I do not plan on stocking the tank further and will not be adding any other polyps or corals. Should I be looking into a CA reactor? <Nope>
Or should I just test the water and add CA as needed? <Test the water and do a water change if calcium is depleted>
Or should I just not worry about it and continue with regular water changes? <Yeah, I like this idea better>
Also, on a completely different note, I am leaving for vacation in a few months (Orlando - Discovery Cove!!!) <Eeewww. Discovery Cove, in my experience, was a rip off. I was extremely disappointed. You get little in return for the cost. I invested in diving instead and now have unbelievable marine animal encounters that are more fulfilling than anything that Discovery Cove could offer. Get certified and spend your vacation dollars on a worthwhile vacation endeavor someplace more exotic than Orlando with lasting memories of seeing a different world than one we are used or one that is simulated for us in
Disney World. But........you will have a good time in Florida for sure. Look into diving!!! You won't regret it.>
.. and I plan to have my family come by and help with feeding (premeasured amounts) and top off (should only need to be done once or twice over the 10 days we are gone). Although the DSB is teaming with life, the grain size of the sand is in the 1mm range, and there are not
a lot of larger meaty pods to get sucked into the pump and put into the display for continuous feeding (there does seem to be
a lot of bristle worms, are they eating the pods?). <Possible but more than likely they are feeding on any left over foods>
I was considering adding a Mysis starter pack, you know, 25 or so live Mysis shrimp, to the DSB in the hopes of culturing live food that would hopefully get sucked into the display regularly. <I like this idea. I do the same. I buy mine from
http://www.aquaculturestore.com/index.html
>
Would this mess up the DSB in any way? <nope. Be sure to feed>
Would the Mysis absorb essential coral elements in the water for their shells and stuff? <Not enough to do any harm>
Is it a bad idea? <To the contrary, a great idea>
Am I crazy? <Not at all>
Any other advice you could give me regarding vacation settings? <Sounds like you got it covered>
Thanks again for all your help! <No worries.....~Paul>
Wants to get it Bigger
Hi guys. <How goes it, Michael here this evening> I'm hoping you can help me out. <Try my best>
Here's a quick tank profile:
90g/20gsump/20gref 2x250w 10k MH 1.025sg 79F. <So far so good>
I'm in college, so most of my stuff is diy. <I think we're all poor as students :|>
Here is my problem: I have been keeping my tank for 2 years now, 1 year in a 55g before I had to move, which
I will have to do again this summer (not far- not that that means it wasn't a pain in the ass the first
time). I only lost one snail during that move! <Nice>
Anyway, I have been keeping a little of everything, but few SPS. I have had good success with almost every coral I
have purchased, and I even had a frogspawn return from a skeleton that had been dead for six months. <Have to love corals' recuperative powers in a healthy system>
I only have a few (8, mostly small) fish. Salinity and temperature are kept almost perfectly constant. My
fish seem happy and soft corals, mushrooms and polyps reproduce fairly rapidly. I even have a neat pink
sponge that has covered almost all of the undersides of my LR. I also have 3 clams- I have had my squamosa
for about a year. <Are they all Squamosas?>
Anyway, things seem to be right, but the growth of my coral (mainly SPS) seems to be
dramatically slow. I have a brown Acropora frag that I have had for over a year, and it has grown maybe a few
millimeters. sad, huh? It's stuck out its polyps every single day and appears healthy, but there is little
growth or encrustation at all, with some bottom-up recession. <When a coral appears healthy and extends polyps as
usual, but doesn't actually grow much, something is deficient. Probably not enough food or not enough light. Acroporas are very light hungry corals (for the most part, there are many species in the
Acroporidae genus), much more so than your mushrooms, as these species are separated
by at least 60' of water in the wild>
I have a purple tortuosa frag that I have had for maybe six months- it hasn't receded, but the growth is almost
nonexistent- definitely unlike the time lapse sequences of acros that I have seen. I have
been using tech cb for quite some time almost everyday as well as Lugol's and I infrequently (~once a week)
add other stuff like magnesium, trace elements, strontium etc in small quantities. I add a little
plankton or black powder twice a week or so. Recently I purchased a ph probe to see if that was where my
problem was. It was around 8.0 during the day, but I have brought that up by drip dosing
Kalk steadily to
around 8.2/8.3 and I'm shooting for 8.4. Sorry about how lengthy this is. Should I be adding more
calcium/buffer or feeding much more plankton? <Well, your calcium levels should be around ~400 ppm if not closer to 450. Acroporas are very calcium needy, being stony corals. As for plankton, it will do them absolutely no good. If you've only been feeding plankton, this is probably why you're not seeing any growth, as they're slowly starving. Acropora sp. are very hungry, and need zooplankton to survive and flourish>
I thought that most of the corals were predominantly autotrophic. <Not nearly, they most definitely need feeding>
I am keeping the SPS frags in the highest flow areas of the tank. <Probably a good idea, but
really depends upon the subspecies>
I have an orange capricornis frag that is very healthy looking and has shown decent
growth (~1.5" in 5 months):(. Also, I have had various xenia colonies, which in my tank seem to move very
rapidly across the rockscape (with little growth) and then they either stay the same size and look good or
wilt. I know I'm doing something right because I have had my mandarin for 1.5 years and a leopard wrasse for
one, a colt coral that I grew from a small piece and now have to prune, and my tank is pretty cool looking
(but I have nightmares about some aquarium hotshot coming in and catching all of the problems I know I
have). If you need anymore info, just write me back. I
want a COLONY, not a one year old frag. thanks so much, Hunter Leber <What all are you feeding? What is your current lighting? A bit more info might help us get to the bottom of this. M. Maddox>
Acropora millepora growth
hello guys,
<Hello - An "SPS freak" at your service :) >
I have an A. millepora that's been in my tank about 3 months
now. happily, it has been growing like crazy, and the new growth is a
very nice purple color with teal polyps.
<Sounds nice.>
here's the thing... in my experience these colonies grow in a pretty random
upward and outward branching fashion. the branches on this one,
however, started out pointing upwards but have now all bent outwards and are
growing laterally and branching very little. the result is a pretty
odd looking colony. I am trying to think of a reason the colony would
want to expand laterally and not upwards, towards the light... could it be that
it is in search of more intense light? (I have 175 10k's with PC
actinics) I am curious to hear your opinion on this.
<Well, Mario, most likely this growth has to do with the current it's
receiving. Generally speaking, the more current you give a coral the compact the
branches will grow. It's interesting point out that many A. millepora specimens
in the wild have a table growth form, so this growth your observing is quite
normal. As long as it seems to be growing, I wouldn't be worried about it at
all.>
thanks,
<Take Care, Graham.>

When do corals grow? 2/18/04
I have found contradicting resources. Some say calcification
happens mainly during the daylight hours and some say calcifications happens
only at night. So what's the truth?
~Chris
<both and either <G>... there is no definitive "time to grow"
for such a wide range of animals we call "corals" [ tube corals, hydrocorals,
octocorals, scleractinians, etc]. I doubt that its even very specific for most
species categorically. Anthony>
Grape Caulerpa stunting SPS growth? 12/14/3
Having ruled out all other causes for my stunted SPS growth (it's not
calcium, for example, the levels are high and Halimeda and coralline algae grow
fine; I also have high current and high light), I'm beginning to
think it's the Caulerpa. do you think that it's likely or probable
that my Caulerpa is killing my SPS and other corals?
<FWIW... inadequate water flow (not enough or not enough of the right kind)
is surely one of the most common reasons for poor coral growth. With that said,
and in address of your concern regarding the macroalgae, "grape"
Caulerpa racemosa, is arguably the most noxious among an already exceptionally
noxious group (The genus Caulerpa). It has been documented to kill fishes and
urchins that consume it to excess... and it has also been shown to inhibit coral
growth (albeit like many other macroalgae). Above all... it is not natural to
keep or find with Acroporids. I sincerely believe that your tank will benefit by
reducing excess amounts of this algae/genus (no need to completely rid). Heavier
use of carbon and increased water changes will also be helpful here. Best

Bristle Worms and Coral Fragments 12/9/03
Hi. I have a question on the coral fragments received from Louisville, KY
MACNA convention. Do you ever take the epoxy off the
coral.
<generally not... you simply wait for coral tissue or coralline algae usually
to cover it over>
Mine is still on. I may not have put on the right kind. It
looks like white putty. The corals are just now starting to get color
and grow a little. I didn't have proper lighting until 3-4 weeks
ago. They were turning white and I think they were dying, but with
130w they are making a come back in my 29 gallon tank. Just leave
them they way they are and don't move them?
<yes... please don't move them for fear of killing them if they are weak>
I am having a lot of bristle worms in Fiji rock. It now looks like
bunches of them. They are white with bristles and getting possibly
four inches long. Can they be attacking my corals?
<they can be a risk to the coral... and in excess numbers are an indication
of excess nutrients from overfeeding, lack of water changes and/or inadequate
water flow (do you have less than 10-20X?)>
Someone at the local fish store told me to try peppermint shrimp and that they
would eat them. No such luck!!
<be warned that peppermint shrimp also nip some corals and clams too... they
are not fully reef safe. Do read though our archives here on wetwebmedia.com to
hear such stories/problems>
What can I do that is affordable?
<better water flow and more aggressive water changes and/or protein skimming
(do add a skimmer if you don't already have one... and make yours work better if
not)>
My 3 clown fish are still in 10 gallon tank until I can figure out the bristle
worms. I've kept them in there until bristle worms under
control. Will the worms hurt them?
<not usually>
The clown fish will be the first fish in the 29 gal
tank. What other fish would be a good mixture in this
tank.
<there are hundreds of possibilities... do browse through our archives and
through some books to make a short list of candidates and then let us help you
from there if desired>
Help!!!! Any suggestions greatly appreciated. Thank you,
Cindy Stantz
<do consider reading Bob's "Conscientious Marine Aquarist" when you
can... it will put so much of the fundamentals of marine keeping into
perspective for you. With kind regards, Anthony>
Color of SPS Corals - 8/29/03
This message is for Anthony Calfo
<howdy>
Anthony, first off thank you for all your prior help in my 75 reef. It
is doing better today than ever largely due to your help. I
also have just purchased your book on Coral Propagation and an getting a lot out
of it.
<thanks kindly my friend>
Setup:
My current lighting is 2 URI 50/50 VHOs and 2 full actinic (440 Watts) + I added
2 96Watt Power compacts one each about 6 weeks ago (added one and waited 3 weeks
for the other). My alk I keep around 10DKH and Calcium around 350
using limewater dripped nightly.
<excellent numbers... keep steady and you do not have to worry about going
higher. Or if you want Ca higher... let the ALK fall to 8-10 dKH>
I also have to add about 1 teaspoon a day of Baking soda and about 15milliters
of Sea Chem Reef Complete (3 cap fulls) to keep these levels with my current
coral growth. I am going to try your method of Kalk dosing you
mention in your book. I am also feeding the fish and corals more
now (your prior recommendations).
<sweet>
My question concerns the colors of my SPS corals in my mixed reef. I
am starting to get really nice looking purple and orange colors out of my Acros
and my Montipora digitata. However, some of my green Acros and
Monti's are still not dark and vibrant as they should be. (My friend, the
Halide nut, wants me
to go to HQI halides. He has much nicer green colors then I do but my
purples are better than his). Does the green colors require more
intense lighting or is it something else?
<your friend is clearly mistaken... or at least missing the big picture.
Cnidarian pigments are as heavily influenced by feeding levels and water
clartity as they are the nature of light. Many factors here... with nitrate
levels (zero is not good... allow a few ppm to linger) and UV penetration (not
MH vs. PC... but glass canopy or no, being the issue here). That said... double
ended HQI halides are excellent lamps. My current fave>
Thanks again for your help.
P.S. one note out of your book. You mention coralline bleaching right
at a water line when doing water changes. I used to have a big
problem with this until I turned off my fans during the change. The
coralline does not seem to die off any more. I always thought the
bleaching was due to the intense evaporative cooling with the fans on.
<it really is a coincidence in your case... do consider that every piece of
live rock imported is out of water for a minimum of 4-7 days dry on import. The
reality of the industry is that unless you live in Los Angeles/port of entry...
your rock was out of water for 7-14 days on import. Air exposure is not an issue
here bub. By chance do your lights turn off with the fans? 'Tis light exposure
then>
Anyway, I really like the book and hope for a "part-two".
Andrew

Color of SPS Corals II - 8/29/03
Anthony, thanks for the quick response.
<always welcome>
I am not sure I fully understand your answer. "and UV
penetration (not MH vs. PC... but glass canopy or no, being the issue here). That
said... double ended HQI halides are excellent lamps. My current fave>"
<my apologies... to be clearer, coral coloration in some cases is a matter of
UV exposure and not a matter of a specific type of bulb. No one bulb (not even
HQIs ;) ] can keep all corals in optimal color because some natural
pigments are stimulated by UV (producing attractive colored proteins produced to
reflect/refract it) while other corals are influenced unfavorably by it. You
could have the "perfect" lamp, if such a thing existed, but with a
glass or acrylic lens, your corals may not get the light they really need (for
other corals... the lens is necessary to prevent excess exposure). Point
being.., lenses clean... lenses dirty... lenses off and lenses on can all effect
coral coloration. So can proper use of carbon (weekly/daily) to maintain water
clarity or not. Coral colors simply are not only about lamp choice. And so...
experimentation will be necessary>
I did forget to tell you my tank is acrylic. I do keep the top very
clean though.
<yes... critical>
Would you say the green digita may not be getting enough UV?
<I could not possibly say for certain... even if we could confirm the ID
correctly, some specimens/colonies come from vastly distant areas of a reef and
have evolved to need different light qualities>
I am trying to feed more and like I said, my purple corals are really starting
to color up but the greens are not dark enough.
<indeed... the feeding is crucial for maintaining coral coloration. And like
the water clarity issues above, it is a double edged sword. Excess
nitrate/feeding can over fertilize corals, so to speak, and cause an
unattractive darkening (often brown). Experimentation>
You are correct about the nitrates. My tank do not register any with
my kit (Salifert).
<If your nitrates are truly zero... then do allow them to creep a bit (keep
under 5 ppm though). I must say, however, that I am not impressed with Salifert
test kits based on consumer feedback I hear>
Also, I am considering metal halides for an upgrade when all my bulbs reach the
6 month point. For my 75 reef considering it is acrylic, I am
thinking of going to 2 175 watt Ushio metal halides and run two full actinic
VHOs with my old Ice Cap ballast (going forward 4 bulbs to replace instead of
6). Would that help "punch more light" to the corals and
help with color?
<most definitely... a nice combination>
It is less total watts than I have now but I feel the halides might be better
here.
<correct... better penetration at depth>
Also, would you recommend a different setup with an HQI halide setup with 2 150s
or 250s?
<i cannot say without a list of species. We must [pick our species and
identify their needs before selecting lights>
I was worried about to much light and heat as I really do not want to over do it
(heat is a concern as I do not want a chiller).
Thanks again. Andrew
<no worries... 150 watt HQIs at 6" off the water or 175 watt
Ushios at 9 inches of the water will be nice either way, to generalize. Be sure
to keep those fluorescents no farther than 3" off the surface though. Best
regards, Anthony>
Eclipse I Hood w/ SmartLite 32 Retro Kit Lighting II - 8/15/03
Thanks for the reply Anthony. All my mates at fishprofiles.com
are laughing their heads off too....
<you are a very good sport my friend <G>. Truly so. It allows us to
answer queries while illuminating other/bigger issues to the masses at large
that read our dailies>
Hobbyist, but, yeah... I'm in an academic environment and mindset lately.
<heehee... not a crime at all. Just do not forget to enjoy the organic
aspects of the hobby in addition to your personal interests of hard science>
Thanks for busting my balls a bit... I know I'm over analyzing... but it's hard
to get a straight answer since everyone has different tank sizes, etc (and
opinions on what will and will not grow).
<indeed... understood and agreed. And much of it is mitigated by the fact
that most corals are so very adaptable to changes in light if conducted slowly.
It's very important to know that deficiencies in light can be easily overcome
with feeding... but the reverse is not true. Point being... err on the
conservative side of lighting (no 1000W MH on a 55 gallon <G>) if you want
more options for corals. And feeding is a very crucial but commonly overlooked
aspect of husbandry>
So I figured I would get objective.... Anyway... if so much will
grow? How about some colorful suggestions (ok....colorful language
too)
<depends on how frisky you are about cutting coral, or no. For the low
maintenance gamut... Tridacna crocea and maxima clam babies are scary slow
growers. Some handsome Porites spp. (yellow cylindricus, purple nigrescens or
green lobata) tend to be relatively slow growing. Blastomussa for the lower
light areas would be great. Most of the soft corals are to be avoided for their
fast growth unless you want to play the other side of the coin (frequent
propagation)>
Will low light grow stuff grow on the substrate?
<many many species, yes... in such a shallow tank>
Would medium light stuff grow on the rocks that are piled higher?
Or am I just getting too detailed again?
<a bit my friend. The tank is so very shallow that you can grow almost
anything with proper feeding and adequate water changes>
Just buy something and see what happens?
<better still... find a group/niche and focus on it... shallow water SPS...
low light LPS or polyps... medium light Octocorals (and frag away), etc>
Thanks, Jeff
<and sincere thank to you again, Jeff for being a great sport. Wishing you
the very best of luck. Anthony>
Bring Up The Lights...Bring on The Corals!
Hi guys,
<Hey! Scott F. your guy tonight>
Just want to let you know how much I've learned from all the info. you've
provided in your website. I've already asked a couple questions before, but I
have some questions on the above topic. 1) Would a 130W CSL or Coralife PC
lighting be sufficient for a few corals and inverts, but mostly fish aquarium?
<Well, yes- or no...(How's that for an answer?)...Really depends on the depth
and length of the tank, and the types of animals that you intend to keep.>
and What type of corals and inverts are hardy with this setup?
<I've kept all sorts of LPS and soft corals successfully with PC's.. Yes, yo |
