Is additional filtration necessary?
Reef tank 9/6/08 I have a question regarding and established 47
gallon reef tank that I have only had for a couple of months. The tank is
testing, and running exquisitely. Let me first explain its makeup: <Ok> 47
gallon column (20w x 18d x 30h) difficult to work on the bottom, but very nicely
shaped in my bedroom. <Be aware that this tank has very low bioload
capabilities due to it's height.> 50 pounds live rock 1 175 w 10,000 K.
halide with two power compact 50/50 Prizm Pro Skimmer (recently changed this
from the regular Prizm that it came with as I have more livestock than the
previous owner. Fluval 205 canister filter (just loaded with carbon)
<Needs to be cleaned weekly at least.> 1 pair Maroon Clown Fish 2 PJ
Cardinals <The clowns may eventually harass these, be prepared to remove one
pair of fish.> 1 Six Banded Wrasse <Can also be aggressive, and with a
tank of this small of a footprint will likely be a problem in the future.> 1
Flame Angel <Needs more room.> 1 Blue Damsel <AKA a blue devil, lives
up to its name.> Frogspawn Devil's Hands A few other assorted corals
that (ashamedly) I do not know the names of yet. My question is, can I,
should I, do away with the Fluval 205. <Could, needs lots of maintenance if
you decide to keep it. However this tank needs lots of water flow due to its
height, so the Fluval may help there.> Contrary to what I have read, the
Prizm is doing a wonderful job on this sized tank. <As long as it is
producing.> No, I would not entrust a much larger tank to it, but for the
money (on sale), it is working quite well. <Good> When I first got the
tank, the guy was running not only the Fluval 205, but another larger canister
Odyssea, and inexpensive canister available on eBay (which I did away with
rather quickly because mine leaked as they are notorious for). <And a lot to
clean.> All I have in the Fluval 205 is carbon, but the Prizm Pro has a
container where I am able to, and have, filled with carbon, etc. . Eventually, I
will probably mix phosphate sponge and carbon into this container. <Would
probably work.> Thank you for your advice. Best regards, Jeffrey
<If you are willing to put in the work a canister can work, but if they are not
cleaned often they can become nitrate factories.> <Chris>
Re: Is additional filtration necessary? Reef tank 9/6/08
I have one power head in this tank, and would consider another. <Yes
definitely, since this tank has such small surface area compared to it's total
size water movement is paramount.> In regards to the Maroon Clowns, is it
possible/advisable to separate them as I have another 120 gallon tank almost
ready for habitation. I could also put the Flame Angel there if necessary.
<I think both would find a 120 a much more suitable home.> <Chris>
Filtration system - 7/7/08
Hi.
<Hello>
I am 3yrs into salt water. I currently have a 55 gal fish only and a 26gal nano
reef tank. I am going to be buying a 150gal tank from Tenecor. It will have an
overflow box centered in the R. side panel as all other sides will be viewable.
It will also have some sort of closed loop circulation system built into it. My
tank will be a mix of coral and fish with live rock and sand. I plan on having
at least 150lbs of live rock. My problem is that with so many opinions on
filtration I am confused. Should I get a wet/dry filter or should I just put
live rock in a sump?
<As you've said, there are many opinions. With as much live rock as you plan to
put in your tank, I don't know if I'd use either- maybe some nice
Chaetomorpha
and a small light?>
If so do I need to provide the rock with light?
<No>
And should I use a protein skimmer as well.
<I (and many others) consider this an uncompromisable component of a reef
aquarium. Look for a skimmer from a reputable maker (read reviews...) and buy
one rated higher than your own aquarium volume>
You guys seam to really know your stuff so I value your opinion.
<Thanks for the support. Benjamin>
Water Circulation (Flow) For a 180g Marine
“Softie” Tank …In Malta!- 07/05/08
Hi,
<<Hello>>
I am Anthony from Malta.
<<Greetings Anthony…Eric from South Carolina here (though currently visiting in
Nebraska)>>
I have a 700 l marine reef tank with mainly soft corals and polyps and I wish to
upgrade the tank's circulation as it is a bit sluggish.
<<Common to most hobbyists’ tanks I feel… I am a big proponent for heavy and
vigorous water circulation in most marine systems. It does so much good, yet is
seemingly often overlooked…or maybe just underestimated>>
The rocks in my tank are forming a slope from the bottom to the top. Can you
please guide me on how many powerheads I have to use, the positioning and the
model? I wish to use the Hydor Koralia.
<<These are a good choice… For this size tank I would recommend the largest
model, the Koralia 4. I would use as minimum of four units (more smaller units
may be needed depending on the rockwork, to avoid areas of very low flow),
positioning two at each end and facing the units opposite to create some random
turbulent flow>>
Thanks in advance for your help and for your great website,
Anthony
<<Happy to share. Eric Russell>>
P.S. Sorry to write this e-mail again but I forgot to enter the tank's
dimension. It is 6 feet by 2feet by 2feet.
Thanks again.
<<Ah yes… in this country this is a standard and popular offering of 180gal
U.S.…a very nice size for such displays. Regards, EricR>>
Protein Skimmer Question 06/02/2008
Good afternoon guys,
<<And Gals i hope... Andrew with you today>>
First let me say your site is amazing, this is my first question to you b/c I
have always been able to find the answers I needed by searching.
<<Thanks for the kind words>>
However for this one I seem to be having a little trouble (although I'm sure
it's here somewhere.) First my set up which has been running for 7 months now
and has consistently had the numbers to follow: 45 Gal. (high), custom show tank
(reef), 55 lbs of live rock making pinnacles and caves modeled on a site/reef I
dived and photographed in the Lembeh Strait, Sulawesi (avid underwater phtog
here), 3 - 5 inches of live sand sloping back. My numbers Ammonia, Trite &
Trates all 0, Ph 8.3, Calcium 423, Mag 1270, DKH 10.5, Phosphates 0 and
strontium 15. Aqua C Remora Pro skimmer and 1 - 150 watt Metal Halide with 14 K
bulb and 1 PC dual compact 80 w (1 pure daylight & 1 pure actinic) all in all ~
6 watts per gallon. Inhabitants are 1 true percula, 2 cardinal fish, a mated
pair of Coral Banded Shrimp (she's constantly carrying and laying eggs which are
a nice supplemental feedings for the tank and both are gentle with the tank
mates - coral not so much), btwn 5 - 10 (of each) blue legged hermits,
Nassarius, cone head and margarita snails. Corals are 6 different types of
mushroom (orange, blue, red and green, 1 Palythoa polyp, 1 open brain coral
(red) and after much reading prior to buying I now have a gorgeous Goniopora sp.
(green) the size of a child's basketball (the ones pizza hut used to give away
at the final four) and that's just when he does not feel like coming all the way
out - he usually does and he's bigger at times and is always out when the lights
are on from day 1 (even in the acclimating container.. =).
<<Sounds like a wonderful setup you have there>>
Well needless to say I love him and have taken it upon myself to read everything
I can get my hands on on their care and difficulty of care. Spot feedings of
Cyclops-eeze mixed with zoo, brine shrimp shavings and DT's oyster eggs several
times per week. OK enough about my tank and on to the real question:
<<Ok>>
I have always been running the protein skimmer constantly 24 hrs. per day except
while feeding when it is off and timed for 1 1/2 hrs. when I first started in
reefing I didn't even think about how long may be good or not good to run the
skimmer. So I started to do a little research and found out others only run
theirs for several hours per day. What would you (the pro's) advise for my
situation and tank?
<<To be honest, personal preference. I would have to say its about a split 50 /
50 of people i know who run all the time, a nd some on timers. Personally, i
don't run one at all. If you can run 24/7, then i don't see any harm in it, this
is usually the common advise to give. Some of the people i know who run their
skimmer for only part of the day, actually only do this to cut down their
electric consumption>>
I'm thinking a timer kicking it on during the night-time & off ___________?
would be nice so I don't have to see all the micro-bubbles = ), but you...?
<<If you have a micro bubble issue with the skimmer, then i would attempt all
avenues possible to rectify this. I do know that sometimes, no matter what is
done, it cannot be stopped. So, if you do only want to run it for part of the
day, then yes, run it through the night while tank viewing is not being done>>
Can you advise a time estimate for my skimmer? Or anything I could read upon for
the Goni, I have all the common books, but maybe I'm missing one or two. Thanks
so much for your time and all you do to help us little guys out. Alex -
Manhattan, NYC where I can't SCUBA dive without a shot...

New filtration for a reef
tank 05/29/2008
Hello WWM crew,
<<Hello, Andrew here, blowing the dust off his keyboard>>
I want to tell you that I have found your site absolutely enlightening.
<<Thank you for the kind words>>
Let me tell you a little about my tank. I bought it used and working from
someone who was getting rid of their tank (5 months ago). It was a 75 gallon
FO glass tank with 2 catfish which I quickly traded for a clownfish and 5
green chromis from the LFS. It had a fluval 404 canister filter and a Remora
Pro Skimmer. 2 powerheads, a Rio 1400 and a MaxiJet 1200 and a 300w heater.
I
bought Bob's book "The Cons. Mar. Acq." and am learning so much, thank you.
<<Sounds wonderful>>
I bought about 35 lbs of live rock, and added 40 lbs of live sand (sugar
grain size) to the sand that was already in the tank (which was coarser than
the sand I added), is this OK or should I separate the finer sand from the
gravel?.
<<Under normal circumstances, I would of suggested swapping the existing
sand, and using just the fine aragonite sand. However, as its already in
there, it should be fine>>
My tank then became a FOWLR, I added a Yellow tang, pajama + flame cardinal,
and an engineer goby. I learned it was good to test the water and do water
changes, which I have been doing about every 2-3 weeks (about 10 gallons).
<<I would suggest going for 10% water change per week, to keep on top of the
trace elements available to the inhabitants>>
My tests had been AMM, Nitrites, Nitrates=0, but PH has been 7.8 all along.
Then about 3 weeks ago I tested the Nitrates and they were 160!!!
<<This could be due to the mixing of the sandbed. Large water changes would
bring this down>>
I became alarmed, I started to read and re-read about
Nitrates, and that is when I found your web site. What an eye opener.
: )
I saw your article on nitrates and learned that I needed to correct the
situation, SLOWLY, so that calmed me a little. Then, yesterday my fluval 404
canister went out on me. So this brings me to you, and why I am writing.
<<Ok>>
I've searched through the FAQ's and the articles, once again, very helpful,
but I would still like to ask you if what I am thinking to do is OK or if
you have a better suggestion.
My goal is to transition to a reef tank. From what I've read, I believe the
canister filter is not a good choice for a reef tank, so it's OK that it
broke.
<<Agreed>>
I've been reading on WWM about DSB and I have about 2.5 inches, I was
thinking of adding more to make it 4 inches, would this be enough for
denitrification?
<<To a certain degree, yes, however, I deem a DSB at least 6 inches. Hence
why most people will utilize a DSB in a sump tank>>
Also, my engineer goby moves the sand around like crazy, would this affect
the DSB?
<<Not really, should be fine>>
I am planning on buying about 40 more pounds of live rock, which I believe
will also help to denitrify. Will this be enough for my tank without a
chemical filter?
<<Yes, that will give you about 75lbs of live rock, which will happily carry
out filtration for you>>
Do you recommend a refugium? It would have to be a HOB because my tank is
not drilled so I cannot add a sump. If so, which one would you recommend.
<<I would certainly recommend a refugium, as these are great for nutrient
export and for cultivating copepod growth. Which to recommend? Well, there
are quite a few on sites like Drs Foster and Smith, Marinedepot.com or
ebay.com which are all basically the same and do the same job. Just ensure
you buy a good sized refugium>>
Someone in my LFS said he did not like refugiums, but I'm not sure why.
<<I am unsure why as well, as these can only benefit an aquarium>>
Please advice on what I should do.
I am also learning that in this hobby there are many contradicting opinions,
so I'm sticking pretty much to what you guys are recommending because you
give pretty good advice, backed up with experience and knowledge.
<<Yes, you can go to 10 sites, and get 10 different opinions. However,
sticking to one good opinion and following it through is a good idea>>
Thank you in advance, I really appreciate your help. I love this whole
saltwater marine ecosystem thing, it absolutely fascinates me.
Thanks again,
Sincerely, Erika
<<Thanks for the questions Erika, I hope this helps. A Nixon>>
Airstone Only, in a Reef Tank?
5/27/2008
Howdy,
<Hi David, Pufferpunk here. For future reference, when you send us a query, you
need to use proper capitalization, spelling & punctuation, as this has to be
fixed by us before posted in our FAQs & is very time consuming.>
I have a 55 gallon with 115 lbs of good cured live rock. It's only been up for a
month now and the only residents are a coral banded shrimp a 3 stripe damsel and
a few snails/feather dusters that came on the rock. The ammonia spiked a week
and a half in and now I’m getting 0 ammonia 0 nitrite and <10 ppm for nitrate. I
have cp
<Power compact?>
lighting, 4 65 watt bulbs and led moonlights (so pretty!). I intend to cover
this tank with mushroom polyps, Zoanthids and either 3 3-4inch fish or 8 1-2
inch fish and many more shrimps and snails.
Ok, here are the questions:
1. I am running filter less. I have a pretty big air pump running to three lime
wood "air stones" spaced one at each end and one in the middle, think this will
work out for me?
<I do not believe you have enough flow in this tank. Water flow is even more
important than light. See: http://www.advancedaquarist.com/2007/1/aafeature
IMO, a skimmer is important too & if you saw the nasty gunk a skimmer removed
from your water, you’d never go without one again.>
2. I have a few extra bulbs and am curious what you think would be better for
this tank. 2 actinic and two 50/50 (that's what I have running now) or two 10k
and two actinic or two 10k's and 2 50/50's or some other combination? Ok, I
reread that and just to make sure there's no confusion, I have 3 10k, 2 50/50 &
3 actinic bulbs and need the best combo of 4 for mushrooms/Zoanthids.
<I think you’ll be happiest with the color & growth you get from 2 10k and 2
actinic. I put the white bulbs in the back.>
Thanks in advance and thank you even more for the site. You wouldn't believe
what a huge help it's been in my research!
<Thank you for the kind words. Please be a help to us & read your letter
carefully & correct before sending. This took more time to respond to than
necessary. ~ PP>
Cheers, David
Skimmer Selection for New
Reef Tank 3/30/08
Hello there Bob & Crew,
<<Hey Mike, Adam J here.>>
I trust this latest inquiry finds you all well.
<<Yes, thanks.>>
Thank you for the help to date as I continue my upgrade (from my 72gal) project.
<<Hope it’s going well.>>
Well, I finally received my Oceanic Model 3 sump to go with my new, but still
dry, Oceanic 72" 215 gal reef ready tank.
<<Has potential.>>
It will include approx. 175-200lbs LR with 3-4" sand base, will be lit by
the Coralife Pro 3 x 250 MH & PC setup (approx. 1150W) and will house 2
Zebrasomas, a Maroon Clown, a Six Line, a Falco Hawkfish, a Coral Beauty, a
Copperband and a Heniochus (plus the usual Brittlestars, Snails, Crabs, etc.)
and a variety of LPS and some softies.
<<Do keep in mind the butterflies may be of some risk in a mixed reef tank.>>
Now, it's skimmer time.
<<As opposed to hammer time…>>
I am at the point where I am trying to decide between two Turboflotor 1000s or
one Turboflotor 5000 Shorty Compact (at about 24" in height). There is
the redundancy of two 1000s and the huge cup capacity of the 5000. There are
just enough pros and cons back and forth that I look to you for some last minute
advice. I suppose, at this point, the question should be as simple as would you
recommend either of these options and if so, which option do you think would
be better.
<<Well honestly, the 5000 would probably be the best choice out of the two,
however as far as the brand goes…I have found them to not be as consistent as I
would like. For the price there are some other choices I would make.>>
If not, is there some other skimmer option that you think I'm missing and/or
should be considering.
<<Take a look at a multitude of brands, it doesn’t hurt to look around and see
which can be adapted to your system...look at Aqua-C, EuroReef, ASM, MRC,
Deltec, Tunze, those are some the common selections . . .see other crew-members
recommendations here;

http://www.wetwebmedia.com/skimbestof.htm
http://www.wetwebmedia.com/skimselfaqs.htm .>>
I'm looking primarily for "in cabinet" (approx. 29") quality and reliability
here. Plus or minus a few bucks here will not be the determining factor.
<<See above.>>
As always, your time and consideration are appreciated.
<<Let me know should you need any more direction.>>
Thank you,
<<Anytime.>>
Mike from Canada, eh.

Moving up to a 110 gallon
system... reading re stkg., canister filters/reef 3/15/08
Hello Crew,
<Cinnamon, let me in!>
I have been a fan of your site since I found it. Great advice.
<Thanks>
Here in my question. I currently have a 60 gallon reef system. I am running a
Marineland Emperor Bio-Wheel 400 Power Filter, a Aqua C Remora Protein Skimmer
with Maxijet 1200 Pump and a Current Orbit(2) 65w Dual Daylight and (2) 65w Dual
Actinic lighting system. Two MaxiJet 1200 powerheads and One 200 watt heater. I
also have about 60 to 80 lbs of live rock and a 2 to 3 inch sand bed.
The current residents of the 60 gallon, (listed below) will be relocating to the
110 gallon mentioned below. Except for the tomato clowns and the Yellow Belly
Blue Damsel. They will be going back to the LFS.
1 yellow tang 4in
2 tomato clowns
1 Lyretail Anthias 3"
1 Yellow Belly Blue Damsel
1 Coral Beauty Angelfish 4"
2 Scarlet Cleaner Shrimp
1 Fire Shrimp
2 Serpent Starfish
1 Hawaiian Feather Duster
15 assorted snails
1 Long tentacle anemone and 1 short tentacle
Several different types of mushrooms, polyps and Zoanthids.
I purchased the 110 gallon tank, (48 x 30 x 18) with no overflow, to be my new
reef system. My plan is to run a Eheim 2028 Professionel II Canister Filter,
<Mmm, good product... I use them on my FW tanks... but am not such a fan for
marine... part. reef set-ups. Please see WWM re:
http://wetwebmedia.com/marcanfiltuse.htm>
two Hydor Koralia 3 - 850GPH powerheads, Aqua C Remora Pro Protein Skimmer with
Mag 3 Pump, two Aquarium Systems Visi-Therm 200 Watt Heater and the Current
Orbit(2) 65w Dual Daylight and (2) 65w Dual Actinic lighting system which is on
my current system. I know my current lighting system will need to be upgraded at
some point, but do you think I will be able to go with this one for now?
<If you can arrange your stinging-celled life to be about the same depth of
water as currently>
I will also have about 75 to 100 lbs of live rock and a 2 to 3 inch sand bed.
Any recommendations would be helpful?
<Deeper, finer substrate is better... also posted: http://wetwebmedia.com/marsubstr.htm
and the linked files above.>
I would also like to add the following resident to the new system, if you
approve? I do not want to overload my system.
2 Maroon Clownfish
1 Blonde Naso Tang. I know he will need to be in a larger system in a couple of
years.
<Mmm, no... immediately. I would not keep a Naso species in anything less than
six feet long/wide... See... WWM... re...>
Already planning on a 180 system.
1 Full size angel?
<... Not a good idea>
Hardy and reef safe any suggestions?
<Posted...>
I know there is no guarantee on it being reef safe.
1 Blue Jaw Trigger or Niger Trigger?
A group of schooling fish. Any suggestions?

Hi Crew
<Hi Garry>
Having been away from the hobby for over ten years (major family illness meant
no time) I am now approaching that time when the reef bug has caught hold and
gone from being latent to rampant again.
<Ah, the bug has bit.>
Much has changed, although I seem to have done much of what is current anyway,
refugia, big skimmers, live rock filtration methods, etc etc (more by accident
than design I might add), and finding your site has allowed the dream and
adventure to begin on a much more solid foundation than before. I know my
stocking rates have always been light and my filtration heavy but it always
worked for me and I only ever seemed to lose a fish shrimp or whatever through
old age or accident. It is good to know that what I did in the past is advised
as being the way to go today.
<Not much has changed but technology.>
So this is just a big thank you to everyone from Bob to Steve to anyone who
replies to the thousands of questions people come up with. Your site has
replaced a lot of faith I have lost with the industry (hobby) what with shops
who don't have a clue (keeping a few small wrasse with an Anglerfish is just one
example), and staff about as knowledgeable (sorry if that's spelt wrong) as a
garbage man in a hospital.
<Thank you for your kind words. James (Salty Dog)>

Garry Holter (in the UK)
Oh I'm an ecologist by training and understand community structure very well (it
formed my D.Phil research for 4 years) and boy does that help in structuring a
reef aquarium. <<Would very much encourage your writing... re the many useful
tie-ins here. Bob Fenner>>

Filtration Recommendations,
Protein Skimmers, Refugium – 1/2/08
Brenda et al,
<Art>
Thanks for responding to my fishy questions!
<You’re welcome!>
I have a 45 gallon saltwater aquarium FOWLR and will gradually change to a
beginning reef fish tank with your help and LFS. Currently I have a wet/dry
filter and typically a nitrate factory. I invested in this when I started my
aquarium 8/30/07. I regret my newbie choice in the filtration.
<You’re not alone in the regrets of a newbie. We’ve all been there.>
Could you provide specific brand and type of filtration that I might replace it
with this New Year 08? I have 5 small damsels, 2 gobies, 1 small clown fish, 12
assorted hermit crabs, 1 black urchin, 1 brown crab and several small/med
snails. I have 40 #s of LR.
<A good protein skimmer is your best option here. I recommend a lot of research
on protein skimmers before you purchase. There are a lot of poor choices that
can be made. I personally use the Aqua C skimmers for my reef tanks. More
information here:
http://www.wetwebmedia.com/ca/cav1i1/protein_skimmer_impressions.htm and here:
http://www.wetwebmedia.com/proskimrart2.htm . Read through the FAQ’s regarding
skimmers. I also use and recommend a refugium. More information found here:
http://www.wetwebmedia.com/refugium.htm . You will want to read all the articles
and FAQ’s associated with refugiums.
Thanks, Art

Filtering materials in reef
tank – 1/2/08
Hi CREW
Wish you all a very HAPPY NEW YEAR.
Now here is my NEW YEAR question.
What kind of filtering materials can be used in a reef tank sump?
I have a 75g reef tank and was thinking of making a sump for it.
Thanking you

Should I Use A Canister
Filter? - 12/31/07
Hi Eric or whoever is on duty this evening,
<<Hiya Ken...Eric here>>
My 90 gallon SPS tank is doing great.
<<Excellent>>
I recently set up a second tank primarily for a RBTA and a pair of Clarkii clown
fish.
<<Neat!>>
I will probably add another 4 small fish and some star polyps and mushrooms at
some point.
<<Mmm, too bad...the tank/anemone would fare much better in the long term
without the polyps and mushrooms trying to constantly poison it>>
The tank is a 46 gallon bow (3 foot length) with about 65 pounds of live rock,
TEK 5 T5 lighting, two Tunze 6025 Nano Stream powerheads, and a Deltec hang on
back skimmer. I am not using a sump. Even though I can make a large % water
change with a couple of buckets of new water, or water from my SPS tank with
this size tank if I ever run into trouble, I was wondering if I should add a
canister filter to my set up?
<<I would...for chemical filtration (carbon/Poly-Filter)>>
If I did this, I would not use the bio media or noodles, and just use the sponge
for mechanical filtration to trap debris.
<<If you do...be sure to clean the filter sponge of detritus one or more times a
week, else the canister filter will become more of a "problem" than a
"solution">>
I could also use it for PhosBan etc if needed.
<<Indeed>>
I have no mechanical filtration in my SPS tank, but the debris eventually will
end up in my sump which I can then clean out.
<<Agreed... And with good strong water flow, the suspended detritus (or marine
snow, if you like) is actually quite good "food" for your corals>>
This tank has no sump. I of course will have a clean up crew for the tank. Do
you think the canister filter is a good idea or a waste of money?
<<Can be quite useful, as described/when maintained properly>>
If it is a good idea, is Eheim still the way to go?
<<Many choices available these days...but you won't go wrong with the Eheim
product>>
Thanks,
Ken

Filtration question, SW...
Reef maint. 12/30/07
Howdy, Crew!
<Hello!!>
I have my 125 display tank in the living room, and 100 stock tank sump in the
basement. I currently run an Iwaki MD-100 from the basement to pump +/- 2000 gph
upstairs. The tank upstairs has about 150 lbs of live rock, a heater, and my
livestock. There was no filtration physically in the tank until I started this
project. The sump downstairs has one of the two system heaters in it, about 40
lbs of live rock, and the protein skimmer.
I am now turning off my MD-100 at 9pm at night, from the sump to the display,
turning on a Rio 2500 in the tank, and the skimmer in the sump. I go from about
2000 gph to about 800 gph. Would the lighter circulation be all right for the
fish at night?
<Should be.>
I have a 1"-2" crushed coral bed. Flow is still decent with the small pump
running. I aimed it at the front glass, so the flow splits and goes both ways.
Even my anemone still has movement.
Candy canes have feeding tentacles out further than I've ever seen them before.
When the MD-100 is off, the sump in the basement catches all the overflow water
(as during a power outage.) That being said, since the water level rises in the
sump at night, I turn on the skimmer at night. If I left it on during the day,
the water level is low enough, it doesn't skim at all anyway. I turn the main
pump back on at 9am, and the skimmer back off.
What I have considered so far:
-Water temperatures being different, so I have heaters in tank and sump.
<Good.>
-Aeration, so I have the display tank pump aimed toward the surface to
facilitate good gas exchange, and the sump has the protein skimmer to move water
and aerate.
<This will help.>
I haven't checked the pH upstairs and downstairs to see if it differs much.
<I bet it will.>
Can you foresee see any ill effects of me doing this? I don't see any problem so
far. It's been 3 days, and everyone appears happy. Even my hippo tang shows no
signs of stress or ich. Some guys from my club said I would lose filtration, but
I know some people don't even use a sump The water still moves, just not
up-down.
<The real downside hear is stability. You are creating two systems every twelve
hours, then recombining them. I have personally seen systems that do exactly
this with good success, mainly for the power savings. I personally wouldn’t,
just for stability sake.>
Any insight would be appreciated!
<I would at least try to get the skimmer running during the day. You may need to
add a little sump next to your big sump (such as a 20 gal tank) to get the water
height to run your skimmer in. Skimming with the setup now is only skimming less
than half the water half the time.>
Thanks and have a safe and happy New Year!
Eric Z.
<Sure will Eric, same to you and yours. Good luck and happy reefing, Scott V.>
Filtration on 80gal Bowfront
12/29/07
Hello Crew,
<Hello, Scott V. with you.>
Thank you for the time and experience you share with all of us.
I've always been interested in keeping a saltwater and tank and was encouraged
to pursue my interest last year when given a 20gal tank. I started up the tank
in September last year with a basic filter, powerhead, heater and live rock. In
October I added a couple yellow-tail damsels and then added a couple of False
Ocellaris Clownfish in November. I was able to maintain good levels and healthy
fish and I had a nice growth of coralline algae. In the spring of this year, I
added a mushroom and then during this last summer, I added a Xenia, which I
unfortunately watched suffer. It was only at its demise that I became more aware
of the need to test for calcium.
<And alkalinity?>
During the summer I also noticed an outbreak of red slime algae and decided it
was time to invest in a skimmer (AquaC Remora).
<Good move.>
Now that the skimmer is running and I've kept up on water changes, I have been
able to maintain a healthy Kenyi tree that is spreading all over the tank, a
leather finger and a leather coral. All this said to say that I am fascinated
with the craft decided I have to expand .I now have an 80 gal. bowfront awaiting
decisions on a filtration system.
Since all I have known is hang-ons, I've been reading up and am leaning toward a
sump and a separate refugium.
<Yes, if you are going to upgrade, this is the way to go.>
Please review and let me know your thoughts on the current design. I would like
to house a reef tank with a medium load of fish, and LR. In terms of corals, I
would like to consider clams, anemone, brain coral, leathers, Acropora, torch
coral, xenia. This is just a sampling of what I am interested in and want to
design for.
<I would skip the anemone and limit mixing the soft corals with hard.>
Since my stand is a bowfront, I am somewhat limited in space. The opening on the
back is 27.5" wide and 30.5" tall and the interior space is 32" wide x 12" deep
by 30.5" tall
1) Sump - Reef Devil Reef Sump by AE Tech (28 x 11x 16)
Compartment 1 - micron bag, skimmer, skimmer pump
Compartment 2 - will use mechanical or chemical filtration as appropriate
Compartment 3 - pump back to tank
<OK>
2) Skimmer - AquaC EV120 or Euro-Reef RS100 (not sure if I should be considering
the EV180). Should I consider anyone of these more than the other. I would like
the quietest if there is a difference as this tank will be in the family room.
<The EuroReef in my opinion.>
3) Pumps - I have not even looked at pumps yet (will once again be interested in
quiet operating pumps)
<Considering space limitations, a submersible, Eheim hands down.>
4) Lighting - 48" Corallife Aqualight Pro (2x150W HQI MH (10,000K) + 2 96W PC +
3 LED)
<Will be fine.>
5) Water Flow - for additional water movement, I am installing a closed loop
system of 1" pvc pipes buried in the base sand (3" bed) with 8-45 degree angles
forcing water into the tank from all sides. I will also have 2 outlets in the
top rear corners. Both the lower and upper system will be run off pumps located
under the tank. These are in addition to the outflow from the sump.
<How much flow do you plan to run through these? Given the size of the tank,
eight outputs low and two above is just too many. If your pump is sized to your
tank this will provide very little dynamic flow. If your pump is sized to your
outputs, this will be way too much flow. Also, I assume you plan to drill this
tank. If you do please check to see if the bottom is tempered, it likely is. If
so, you will not be able to safely drill it. >
6) UV Sterilizer (to be added in the future)
<I would skip this.>
7) Refugium - Ecosystem Refugium 100M (24 x 8 x 8) - considering adding this in
the future on top of the sump
<I suppose this could work. For the money spent on both the refugium and sump, I
would consider having one made that simply incorporates both into one design, or
possibly fabricating yourself.>
Sorry for the lengthy post. I'm just really wanting to do this as right as
possible the first time.
<No problem.>
Thank in advance.

<Welcome, good luck, Scott V.>
Marine Filtration 9/27/07 – 9/27/07
Hello all (esp. Scott F.).
<Hi Stan, James with you today.>
After avoiding a mistake (putting too many or too big a fish in my 75 gallon
tank), I am now focusing on filter design and set-up, and committing to wait at
least a month before adding any livestock. I now have my kids doing research
with me, so they understand proper husbandry and care requirements (okay, they
are 3 and 6, but they are at least involved).
<Ah, no better time to get them started.>
It looks like I am going to set up a fish only tank (with small fish!) then
converting over to a reef set up later on, so I want to make sure that my sump
design is on target. I am looking at a 29 gallon sump, which will hold about 12
gallons or so in the lower portion, with a separate refugium chamber fed by a
powerhead (expect about 150 gph) which will flow back into the main sump. I'll
use the refugium chamber as a bubble trap, along with a filter pad on each end.
For skimming, I'll have an Aqua-C Remora on the main tank. Flow through the sump
itself should be about 450 gph.
The display will have 80 lbs of base rock, along with a 1" bed of live sand, and
about 10 lbs of Tonga live rock to seed the base rock and add some variation to
the look.
In the refugium, I plan on placing a 5" DSB along with 5-10 lbs of live rock
rubble.
<I'd go no more than 3">
I hope to order some benthic organisms and macroalgae online, as my LFS doesn't
have them.
Question...will this set up work for a reef tank (I'll add more circulation via
a closed loop at that point) as well as for my small fish only system?
<Should be no problem but I'd go with more live rock before you convert it to
reef. It would take quite some time for the 10 pounds on Tonga to seed the 80
pounds of base rock.>
I keep searching and reading, and I am especially grateful (and impressed) that
there is a common thread with all your responses, and no real contradiction of
information.
<Why thank you.>
Thanks again for all you guys do!
<You're welcome. James (Salty Dog)>

Confusion; Sumps, Refugiums, Wet/Dry
Trickle Filters, Flow Rates, and Wavemakers – 09/21/07
Dear Sirs,
<<Greetings Carl...and BTW, very capable ladies here as well>>
I love your site.
<<We thank you>>
I am still fairly new to this hobby and am pulling my hair out at the variety of
information available.
<<Mmm, yes...much info with varying opinions...but do keep reading/absorbing>>
I have made some progress, but have recently decided to take a step forward and
it just so happens that this next step seems exceedingly baffling.
<<Indeed, many hobbyists are intimidated by the plumbing/flow/circulation
aspects of tank setup...let’s see if I can help with your understanding re>>
Currently I have a 46-gallon bowfront with a wet/dry which returns via an
Aquaclear 70 powerhead. I have ordered a refugium and plan on turning the
wet/dry into a sump (I will then use both the sump and the refugium), but I
really can't figure out the plumbing for this.
<<Quite elementary really... The tank drains to the skimmer chamber of the
sump...a T-fitting is installed on the drain line with a gate-valve on the
output, and leading to the refugium...the refugium then “gravity drains” to the
pump chamber of the sump. Plumbing the vessels in this manner lets you
adjust/maintain a different flow rate in the refugium if you wish>>
In my setup, both the sump and 'fuge must be below the aquarium.
<<Very common...and is how my system is configured. Depending on the height of
the individual vessels, you may find you will need to elevate the refugium
slightly to allow it to gravity drain to the sump>>
Besides plumbing, I am also confused by flow rates.
<<Okay>>
I understand that the aquarium flow rate should be higher than that of the
refugium, but how much exactly should I be aiming for...i.e. aquarium 8xhr?
refugium 2xhr?
<<Is variable...often dictated by the animals/species kept. But as a general
starting point this would be fine...could even add a couple more “volumes per
hour” if you wish>>
Is my Aquaclear 70 adequate?
<<As a means for circulating water through the sump/refugium, maybe...depends on
how much head-loss you experience with this pump...but is likely inadequate on
its own re water movement within the display>>
Wavemakers: I ordered a Wave2k before I read your opinion on them. Should I
return it?
<<Mmm, I’ve not used one of these devices...but I think it will overpower your
46g tank with both its size and performance. The Koralia or smaller Tunze Stream
pumps would be a better choice here...in my opinion>>
I was planning on keeping it and augmenting in tank water flow with a Koralia
#1, a Koralia nano for bottom of the tank water movement, and the return from
the Aquaclear 70 of course.
<<Ah well...you don’t need (or want!) the Wave2K then>>
Thanks,
Carl

Filtration Sequencing... What Is The Best
Filtration Sequence For A Reef Tank? – 09/19/07
- Biological, chemical, mechanical.
- Biological, mechanical, chemical.
- Chemical, mechanical, biological.
- Chemical, biological, mechanical.
- Mechanical, chemical, biological.
- Mechanical, biological, chemical.
<<Mmm, well...biological filtration is going on most “everywhere” in the
system...but if setting up/arranging sequential filtration modules, it is my
opinion the last sequence listed (mechanical, biological, chemical) is the best,
for “any” marine system. Mechanical filtration first (changed or cleaned
frequently) to trap and remove detritus/organic material to reduce the load on
the bio-filter (I consider a protein skimmer such a device)...biological
filtration next, to process “dissolved” organic compounds...and lastly, chemical
filtration to augment these processes and help reduce toxic levels of those
elements not handled by the previous two methods>>

Re: I am going crazy!!! (revised, I hope this is better!!)... Reef tank
filtr. mainly 4/25/07
Hello Mr. Fenner and crew,
<Jerry>
After all the late night reading and studying, I find the more I read and learn,
the crazier I feel I am getting.
Here is my dilemma, I wish I can say I was one of the ones that studied first
and purchased second, but I wasn't. Put that together with impatience and you
have a disaster waiting to happen.
I have a 75 gallon LR/LS reef tank, stocked with everything the LFS could sell
me, (huge amounts of corals).
I have a small 17 gallon wet dry (18"x10"x16") and a 405 Fluval (contains bios
and Purigen). I have an Aqua C Urchin/Mag sitting in my sump and next to that
is a Rio 1250 gph. The Rio returns directly into the left side of my tank.
Since I was out of room in the sump, I put a Pondmaster 2400gph outside.
The Pondmaster is pumping water to a JBJ chiller through a wall into the next
room (it took weeks to convince my wife!!).
This returns to the right side of my tank making a travel of 5' each way.
I had perfect water for months and now it seems the water changes are not
keeping up with the production of nitrates.
<... You have read re Wet-Dries on WWM:
http://www.wetwebmedia.com/bioballfaqs.htm
and the linked files above?>
I was past 240 and did a 30 gallon water change, and now it's down to 100. I
plan on doing another big change in a couple of days. (yet my corals/fish seem
fine?)
I read from your site to remove bio-balls, I did that and replaced it with 4" of
live sand and 16lb of broken live rock. I have also added 2 full bags of
Chaetomorpha to the sump/refugium.
I am still going through the drip plate and PolyPads dropping down on top of the
Chaetomorpha and LR/LS. Is this okay?
<Yes>
I started to feel that this refugium is not enough (always my problem), it is
currently 8"x10". I have read that any refugium is better than no refugium.
<This is so>
Now I have so much water in the sump/refugium that if I had a power outage, I
would have about 5 gallons or more on the floor and a divorce!!
<Trouble... need to reduce the amount of water in the tank/system...>
Recently I bought a new tank 24"x12"x16" for a separate refugium. I would go
bigger but I have space constraints.
I have just recently read about this miracle mud. So now my brain takes me to
another direction.
Tank water through the drip plate/poly pads into the miracle mud compartment.
Flow through to the skimmer side, Rio 1250 taking it through the wall 5' to the
refugium.
Pondmaster 2400 will take it from the refugium to the chiller (too much flow
into chiller?)
<No>
and back another 5' to then split to both sides of the tank.
Is this crazy or should I just keep it simple?
<Simple is better... Do read re how much flow to send through/over the Mud...
not much. Best to restrict flow or bypass through this compartment>
Either keep things as they are and purchase a Sulphur Denitrator.
Pull the sump/refugium out; replace it with the new tank/refugium and put it
under the display and call it a day??
<I would do the latter>
PLEASE HHEELLLPPP!! I don't want to hurt anything in my tank with my constant
changes.
Ps I have a red Caulerpa in my tank and it has grown large dark purple almost
black grapes on them is this normal?
<Possibly... better to remove this material if it starts to decompose. Bob
Fenner>

Here comes another addiction... going to reef! Mainly filtr. -
4/7/07
Thank you guys so much for putting real and honest info on the web for
all to use free.... You have no doubt saved countless marine lives... After
making it a point to read info on your site ever day when I get home from work
for a couple hours, you might get some mail from the woman that's not
so pleasant.. j/k)
<Heeee! Say it isn't so!>
Anyway after all the info from you guys I am going to ditch my wet/dry system
and build a custom 55 Gallon sump. Finally here comes the question... I have a
180 gallon aquarium, 15 fish, some inverts and a button polyp, all medium size,
finally ready to get bit by the coral bug. 225 pds LR, 220 pds Fiji pink sand,
2 Mag drive 12 pumps, one going to a large lifeguard chemical module with a
little reef carbon, and one going to a large lifeguard mechanical module,
<Mmm... not such a fan of this sort of filtration for this application... Do
plan on switching out the cartridge every week (have at least two... with the
one being cleaned in-between...>
2 Coralife 220 skimmers, and an 18 W UV, a hang on refuge (which will be
replaced in the new sump.
<No room to squeeze in one of larger volume?>
Should I just remove the modules and use the mag's for return only due to all
the live rock and sand, as well as a future large refuge in the sump with
Chaeto?
<Yes... a better plan>
I figure I would take them off and utilize the extra flow potential from the
pumps.. Thanx again!
<Ah yes... we're in agreement here. Bob Fenner>
If it's not broken don't fix it; too much filtration on a reef tank?
4/6/07
Hi guy's, love the site,
<Thank you.>
have been reading it for a while and am wondering if I am using to much
filtration...
<Hard to do...generally speaking. but let's see what we have.>
I have a 180 gallon reef tank about 12 fish,
<Small? Big?>
5 inverts, and 1 star button polyp. Here is what I have on the tank.. 225 pds
LR, Overflow to a large sump with about 100 bioballs. A mag drive 12 running to
a lifeguard {large) mechanical module. A mag12 running to a lifeguard (large)
chemical module, about 1/2 full of reef carbon. A Coralife 220 skimmer, ORP
monitor going to a small ozone generator, 200 pounds of Fiji pink sand, a CPR
large refugium with Chaeto lit 24/7. I feel as though I might be wasting a lot
with having all this...Any suggestions?
<I think the plastic bio-media is a unnecessary, but the refugium probably
refutes most ill effects it creates. From the sounds of it you have a
functional, stable captive environment. It it's not broken don't fix it. The
carbon, unless you have a lot of encroaching cnidaria life is probably not
necessary on a continual basis either...but won't hurt anything either.>
My fish are great, water chem great, and water crystal clear....Thanx in
advance

Upgrading tank help! Using WWM 3/1/07
I want to upgrade my current tank that is 75 gallons with shells for
substrate, 2 Eheim 2026 canister filters, aqua c pro skimmer, live rock and
heavy bio-load due to a lot of live stock. All tests are ok, but the nitrates.
<The canisters... need to be cleaned frequently... at least weekly>
The new tank is a 150 gallon with 4 1" bulkheads drilled in the back.
<I wish two were 1.5"... for drains...>
I have a sea life model 150 wet/dry filter that measures 28x16x9 1/2. The sump
area is 16 1/2 and the bio-ball area is 11 1/2. It also has a Rio 2500 return
pump. About 1" of sand and then the pre-existing shells and live rock.
Here are my questions. Will this wet/dry be sufficient for this size tank?
<Mmm, can be, yes>
Since I don't have a ton of live rock, should I use the bio-balls or leave them
out?
<I would leave out>
(I plan to increase the amount of live rock when the $$ increases ) Would I
benefit from leaving out the bio-balls and adding LR to the sump area?
<Yes... posted>
Would the use of the Eheim be any benefit?
<Not IMO>
Is the 1" of sand ok, or would more be beneficial?
<Posted>
I have also read your skimmer should be placed in the rawest water. Should the
skimmer be placed in the bio area? is the sump area ok?
<Ditto>
Should I add a bag of Chemi-pure before the sump area? Could you tell me which
is the better-Chemi-pure or black diamond activated carbon?
<The former>
Would this set-up be ok to get up and running then modify with time?
Thanks for your valuable time and responses.

Experimental staging tank - 02/09/2007
Hi Bob/Crew,
If you would allow me to prevail upon your collective wisdom...
<Well, just my small part>
I have reached a point where I need a sanity check in designing an
Experimental 4 Ft tank that will currently serve as a pre-staging area
for a larger 600 litre reef tank which will not be filled for another 6
months or more, as I wish to plan it very carefully (oh YES..........
there will be questions!...., but still researching for now). When the
Main tank is completed this Experimental tank will become a
fragging/quarantine tank. (Ever had a wood grain 600 litre tank in your
living room that you must resist filling......
<You HAVE got discipline!>
yes, I have nerves of steel, and laugh in the face of the spindly
killer fish) Please be tolerant (cover you mouth when you laugh) , some
of my notions may not be practical , but I have devoted many hours of
research and planning, and literally hundreds of hours on your website
over the last couple of years (no joke). I am attempting to build a
small sump/refugium which will take care of wet/dry nitrate production,
skimming and denitrification ,.... in that order actually. Have attached
a pic, tried very hard to make it clear and understandable, hopefully
succeeded. I am aware that this is a fairly small sump and refugium, but
I am struggling for space. The basic concept is :
Partition one :
Loose floating bioballs under the dump pipe with 2000 LPH Air/Water Pump
<Mmm, why this here? I'd rely on gravity>
to skimmer and overflow to partition two (skimmer). Hopefully being
agitated by water flow will help prevent debris trapping and will
nitrify my ammonia/nitrite for me without becoming too much of a debris
trap.
<Shouldn't be an issue>
Partition two:
Aqua-One SK388 Skimmer (took your advice and got one at last) with
enclosed, perforated plastic boxes full of ceramic noodles beside it,
overflowing to Refugium. OK here's the part where I want you to try not
to laugh...... The idea being to encourage an anaerobic environment in
the boxes for Denitrification whilst still maintaining the 1ppm O2 plus
requirement to prevent Sulfide production, I may "feed" these suckers
carbon, or I may not, do you think I should?
<I would>
Do you know how I can tell if these become Sulfur factories? .
<Likely won't... but might smell it if so>
On the bright side, if they don't work, I can just pull them out since
they're boxed.
<Yes>
Partition/Box three:
Refugium with Live Rock (a little) , Ulva as Macro algae (readily
available to me from sea)
<Mmm... Ulvales are not the easiest macros to culture...>
and either a DSB or whatever brand of Mud I can get here in Australia if
any (we really lag a long way behind you guys in marine technology, half
the stuff you guys talk about we just can't get here. Even something as
simple as Aragonite is not easy to find, in Melbourne anyway!) 2000 LPH
Water pump (will probably enclose) returning to Spray bar.
<Mmm, do look into Loc-line... other distribution here>
should I tee this back to the refugium now , or just wait and see what
the flow is like? Do you think I would be pushing it to try for a DSB in
this tiny and short refugium?
<I'd arrange bypass of some of the flow here... with adjustable weirs
perhaps>
Only have 2mm Coral sand at the moment and feel I would probably have to
go about 4-5 inches plus to make it anaerobic, don't think it will
fit?? How deep does miracle mud etc need to be?
<An inch or more... you might be able to collect your own...>
Well , what do you think?, have I gone mad at last? I really hope so,
would explain so much..... I feel constantly nagged by the concept of a
wet/dry being so good at Nitrate production and yet not being able to
find anything stable other than live rock or DSB's to deal with the
Nitrates, not interested in
chemical treatments , not an elegant solution. I realize water changes
will still be necessary , but am trying to build as stable an ecosystem
as I can manage.
<You have many good ideas here... But I would add another intake drain
of about the stated 1 1/2" size, and do away with the valve
illustrated... not necessary>
In the same vein of questioning, have seen Anthony and others comment
that submerged bioballs are a bad idea, but I can't work out why?
<Inherent design... much more useful in oxygen rich environments... not
sat. (7,8 ppm.) vs. 210,000 ppm...>
seems to me that if you had a coarse prefilter, flowing to some wet/dry
bioballs followed closely by some submerged bioballs in an area of low
O2,(ie Debris
filter->Nitrification->Denitrification) this should be good, .. no?
<Mmm, no... presence, even hypoxia negates anaerobic microbe metabolism,
presence>
Is it because the balls are just not porous enough to foster anaerobic
conditions?
<This and a lack of surface area per volume>
The reason I ask is because , in a misguided moment (listened to LFS. Ho
Ho..) I purchased a 2600 LPH Minjiang Canister filter with 5W UV for
the 600 litre tank when I bought it ( as they said the glass was
probably tempered and couldn't be drilled) then I went one worse and
bought a stack of bioballs to put in it. The thing is... when I watch
the hoses with the air valves shut completely, I see no air going in and
none coming out, does this mean I can assume
it's at least partly anaerobic in there, or is there so much dissolved
O2 that this is never possible while it's flowing.
<Bingo>
I just want to know if I'm doomed to high nitrates and frequent water
changes in the 600 litre display , or if there is some way I can still
use the canister for bio - filtration but avoid this.
<Canisters... not really useful for denitrification... too much flow,
too little media volume... though use of sintered glass, ceramic

Do you know of any other way I could filter a system that can't be
drilled besides a canister? (Oops , there I go.. said I wasn't going to
discuss the 600 litre now.... sorry ). I can leave the canister doing
just mechanical and chemical and circulation , but I really think this
is a waste, although I will have a Weipro 2014 Hang on skimmer and Live
rock as well.
<Do look into having this tank drilled... yes, though tempered, can be
done... the larger LFS, glass shops...>
By the way CMA and Reef Inverts are very difficult books to get in Oz,
<See Readingtrees.com for Antoine's distributors there>
everyone I've asked says 3- 4 months wait , do you have a distributor
here, or will I have to get them online? Which book do you think I would
benefit more from with respect to reef keeping?

Experimental staging tank, Continued - 02/11/2007
Bob,
thanks very much for taking a look at my plans,
But of course one answer generates ten questions............ .
<Ah, yes>
I am attempting to build a small sump/refugium which will take care of
wet/dry nitrate production, skimming and denitrification ,.... in that
order actually.
Have attached a pic, tried very hard to make it clear and
understandable,
hopefully succeeded.
I am aware that this is a fairly small sump and refugium, but I am
struggling for space. The basic concept is :
Partition one :
Loose floating bioballs under the dump pipe with 2000 LPH Air/Water Pump
<Mmm, why this here? I'd rely on gravity>
<<The venturi? (probably not correct term for this) that came with the
skimmer is designed to sit on the front of a specific pump intake and is
very effective, I'm not sure of a good way of getting it inline with the
down pipe like a normal venturi, hence decided to stick with pump, plus
wasn't sure what force was going to be generated.. >>
>Ahh, sorry for this... Yes, the skimmer will need this pump... and/but
the skimmer needs to be in a "partition" entirely, or there to be an
overflow of incoming water... not possible to balance the overflow from
the main tank...<
to skimmer and overflow to Partition two (skimmer). Hopefully being
agitated by water flow will help prevent debris trapping and will
nitrify
my ammonia/nitrite for me without becoming too much of a debris trap.
<Shouldn't be an issue>
Partition/Box three:
Refugium with Live Rock (a little) , Ulva as Macro algae (readily
available to me from sea)
<Mmm... Ulvales are not the easiest macros to culture...>
<<Hmm... this is true... have tried before with Ulva in display tank
which
gradually diminished to nothing, but had the feeling someone was
munching
on it ,(maybe Pseudochromis bicolor?),
>Not likely to its exclusion<
will see if Chaetomorpha
(prolifera?) is available, but doubt it.>>
>Ask around... other national hobbyists...<
..2000 LPH Water pump (will probably enclose) returning
to Spray bar.
<Mmm, do look into Loc-line... other distribution here>
<<What's wrong with the Spray bar?, not enough movement?>>
>That... from restriction and the loss of ability to direct, re-direct
flow direction<
should I tee this back to the refugium now , or just wait
and see what the flow is like?
Do you think I would be pushing it to try for a DSB in this tiny and
short
refugium?
<I'd arrange bypass of some of the flow here... with adjustable weirs
perhaps>
<<Don't think I have enough space to employ adjustable weirs (only
about
30cm X 30cm), maybe the tee from return going back to refugium , with
just pump in a weir?>>
>A good idea, yes<
Only have 2mm Coral sand at the moment and feel I would probably
have to go about 4-5 inches plus to make it anaerobic, don't think it
will fit??
<<would the inches here be right?>>
>Yes<
How deep does miracle mud etc need to be?
<An inch or more... you might be able to collect your own...>
<<Don't think I'm brave enough, any clues on how to tell what sort?,
have
ordered some CaribSea Aragamax online in any case, managed to find
some.... Whew, not cheap!, do you think 3 inches of sugar-fine will do,
or
am I being stingy to my detriment !>>
>Should be fine<
<You have many good ideas here... But I would add another intake drain
of
about the stated 1 1/2" size, and do away with the valve illustrated...
not necessary>
<<Valve/Tap is mainly just so I can turn off flow to work/clean in
sump>>
>Do please check, make sure that in the event of a power or pump failure
the water will not overwhelm the sump<
In the same vein of questioning, have seen Anthony and others comment
that
submerged bioballs are a bad idea, but I can't work out why? ,
<Inherent design... much more useful in oxygen rich environments... not
sat. (7,8 ppm.) vs. 210,000 ppm...>
<< Do you mean that 7-8ppm would be submerged...vs. Wet/Dry at
210,000ppm?
>Yes<
I realize this is better for Nitrification, just wanted to know if you
can
use them in more anaerobic conditions for Denitrification?>>
>No, cannot be used for such<
seems to me
that if you had a coarse prefilter, flowing to some wet/dry bioballs
followed closely by some submerged bioballs in an area of low O2,(ie
Debris
filter->Nitrification->Denitrification) this should be good, .. no?
<Mmm, no... presence, even hypoxia negates anaerobic microbe metabolism,
presence>
<<Whoa!.. sorry, lost you here ,....presence of what?,
>Of any measurable dissolved oxygen<
are you saying that
Anaerobes don't likely completely hypoxic conditions?>>
Is it because the balls are just not porous enough to foster anaerobic
conditions?
>Correct<
<This and a lack of surface area per volume>
.....<Canisters... not really useful for denitrification... too much
flow,
too little media volume... though use of sintered glass, ceramic
media...>
<< Does this mean if I use something like Aqua-one CeramiSub (looks a
bit
like ceramic live rock rubble) that I just bought, I might foster some
small anaerobic pockets in this canister of mine, otherwise I may have
to
try for a hang-on 'fuge, not likely to get past management though (yes
...
married)>>
>I would use such material... though, you are correct that it is of
little use in such a setting (canister)<
Do you know of any other way I could filter a
system that can't be drilled besides a canister? (Oops , there I go..
said
I wasn't going to discuss the 600 litre now.... sorry ). I can leave the
canister doing just mechanical and chemical and circulation , but I
really
think this is a waste, although I will have a Weipro 2014 Hang on
skimmer
and Live rock as well.
<Do look into having this tank drilled... yes, though tempered, can be
done... the larger LFS, glass shops...>
<< Can't seem to find anyone prepared to do it ( even had to drill my
own
hole on the experimental tank ... 1 hour with a Dremel and a diamond
engraving bit/water.... whew!!),
>Nerves... and patience for sure<
and I understand that if I do find
someone to do it, they won't take responsibility. Blew the budget with
this tank , if they break it it's over., can't afford to replace.... : -
(
Actually, I originally spent over a week designing (copying.. ) and
building a beautiful hang on overflow siphon box, only to throw it in
the
bin after reading more negative opinions on WetWeb and thinking long and
hard about the anxiety factor at 4 am, ah well..>>
Which book do you think I would
benefit more from with respect to reef keeping?
<Modern Coral Reef Aquarium series by Fossa and Nilsen>
<< Are you just being modest here, I was referring to CMA vs. Reef
Inverts., was hoping to buy one of these to support your hard work. If
you
truly think the Fossa book will be better for me I will get it, but
would
still like a copy of Reef Inverts.>>
Thanks again
Rama
>Ahh... Your writing presents itself as you being a bit beyond CMA, yet,
yes to the RI book... I do believe you would gain by its perusal...
enjoyably even! Cheers, BobF> |
Marine Tank Set-Up Mucho Research needed. Reef filtr. 2/4/07
WWM Crew,
<Hi.>
I am making the switch from Fresh to salt water aquariums.
<Cool....>
I have a 75 gallon tank, and since my freshwater tank was really overstocked
I
have a lot of filtration.
<Ok.>
I have an Eheim Classic, and two Penguin 7000s hang on filters. I was wondering
besides a protein skimmer if there was any other filtration I would need.
<Well I don't think that you have is appropriate for a reef tank, personally I
prefer to utilize live rock as a means of bio-filtration....look into a skimmer
+ macro algae refugium combo.>
I want it to be a reef tank, and I will be stocking it with tangs and maybe a
butterfly fish or two.
<Mmm...you may want to research this stocking list...thoroughly before
materializing this tank so to speak..."hint + hint.">
What will be the best protein skimmer to use for my 75 gallon tank?
<What type of set-up are you using (sump/hang on...) how much you willing to
spend? AdamJ.>
Marine Tank Upgrades, filtration options 2/1/07
Hi guys,
<Hi Matt.>
Thanks again for the job you do.
<Thank-you for the compliment.>
I have a 55 gal setup with around 55 lbs of live rock, 2 MaxiJet 1200's, emperor
400, and a Coralife SuperSkimmer.
Livestock includes a flame angel, 5 chromis, very large coral banded shrimp, 5
peppermint shrimp, and lots of snails and hermits. The tank mostly stays clean
and clear and the coralline growth has really taken over (tank is 8-9 months
old). However, I know the emperor isn't really appropriate; especially if I
want to switch to a reef tank.
<No, not my first choice.>
Also, the SuperSkimmer doesn't seem particularly effective.
<It's "ok"...again not my first choice, though a lot of people like it...for the
price.>
It pulls out some gunk, but I could probably go for a month without emptying
it.
<That's no good....is it tuned properly?>
I'm trying to upgrade the filtration on a budget.
<I understand.>
A dedicated sump is not practical right now.
<ok.>
I'm considering either a skimmer upgrade (possibly a remora or remora pro)
<Good brand of skimmer.>
or removing the emperor and adding a hang on refugium.
<Awesome.>
Eventually, I'd like to do both.
<Even better.>
In your opinion, would a better skimmer make a big difference?
<I would rather the remora than the Coralife if we are being honest...though I
think the refugium replacing the emperor will make the largest difference.>
Also, would I be making a mistake by taking away the mechanical and carbon
filtration that the emperor provides?
<I don't think so...no...keep it on hand (in a closet) if you need a means of
running carbon or something like that, down the road.>
Things are OK now, but I want water conditions to stay as pristine as possible.
<Sounds good.>
On a separate tangent, my current fish are healthy and happy.
However, I have had bad luck trying to add gobies and blennies. They seem to
disappear when I'm gone for a few days and the coral banded shrimp ends up
molting within the week. Could he be capable of devouring a smaller goby or
blenny in just a few days with no signs of the carcass?
<In a tank of this size....easily...food does not go to waste in the ocean.>
Thanks, in
advance.
<Welcome.>
Matt

Two Questions... re... reef set-up... can. filtr., top-off water prep.
1/27/07
Hello,
<Hey Joe, JustinN with you today.>
First and foremost I would like to thank you for all the resources you provide.
<Thank you for this.>
I bought and read Bob's book and am constantly looking through these pages while
I slowly put together my 65g FOWLR.
<Ah, yes, is quite an excellent book... hard to put down!>
I have a couple of questions that are a little confusing to me and would like to
have your point of view or answer:
<Alright, I'll give it a go>
1) I will be using roughly 75 pounds of LR, a Remora Pro with Mag 3 skimmer
(which I gather from many sources is excellent), and I also bought a canister
filter (Eheim Classic 2215). The last point is where I am a little confused. My
LFS tells me that I could either use a few blue coarse filter pads, with the
white fine pad, and the carbon pad, or the second option would be to run it on
empty just for the extra movement (Please note that I will be using a Maxi-Jet
1200 for extra movement as well). Based on your understanding and the setting
that I have, would it make sense to run it on empty instead of using the media?
If I use the media are there types I should not be putting? If I run it on
empty, what potential problems could arise and should I be looking for?
<I don't think you'll see any detrimental effects from running this canister
filter empty, but I don't think the biological media is really necessary. I
would utilize this for chemical media, such as a bag of ChemiPure or activated
carbon, whatever your choice here may be. When the chemical filtrant is not
needed, you could run the canister empty with no deleterious effects.>
2) I will follow the books advice and do weekly water changes and at the same
time, prepare the water in a trash can to age in my garage for a week with a
heater and a pump to use the following week. I am a little uncertain about how
the freshwater top-offs should work. I think I understand that the best way is
to use our judgment and replace the water as we see necessary (a couple of times
a week), but how to do it is the question mark for me. Does top-off water need
to be aged? If so, how long and how (airstone, small powerhead...)? If you could
just briefly explain how I could prepare the top-off water or point me to the
right link I would greatly appreciate it.
<You've pretty much got it, dead on already. The freshwater should be aerated
beforehand, to help drive out excess CO2 levels and stabilize the water's pH
readings. As you suspect, the top off is simply to refill the excess that has
evaporated; that is, wherever your running level of water was to begin with,
will be where you refill to. This is to help keep the salinity stable, without
fluctuations. Either an airstone or powerhead will be more than sufficient
here.>
I'm a very enthusiastic newbie and want to make sure that I get it right, so
forgive me if these seem like "easy" or "obvious" questions.
<Not at all, my friend. They are refinements of specific situations, which shows
signs of you reading and investigating answers on your own. The 'easy' questions
that that could be considered troublesome, for lack of a better term, are those
that come to us with absolutely no research behind them, and furthermore, that
respond back to us asking the same question again, without really reading our
responses.>
Thank you very much and please keep up the good work!!
Joe
<Thank you for the kind words, Joe. Hope I've helped you here! -JustinN>
Marine filtration question 3/22/07
Thank you for the response JustinN.
<No problem, Theron, sorry for the delay on this one! *grin*>
San Antonio huh? I have to say lucky you. San Antonio is a wonderful place,
with wonderful people.
<It's got its moments, but personally, I'm from the coastal bend -- Corpus
Christi to be exact -- and I never feel right away from the coast, even after 16
years of living in San Antonio..>
We will be at Sea World for spring break in a couple of weeks.
<This was just recently, hope you had fun!>
Thank you for the suggestions. I have no live rock in this system. Just a nice
structure of the "holey" rock The one with the holes, hasn't been blessed as far
as I know) so my fish can sleep and swim around in there. They seem to love it.
Would just the bio wheel be enough anyway?
<Should be sufficient, though I always like to have some live rock in a system
for its aesthetics as well as natural filtration. Not necessary, but certainly
helps.>
I am feeling pretty good about the progress of this system, even though it has
been running for over six years now, I do think it is a healthy system.
<I would think you are correct here.>
I have had this cell pore cartridge since start-up so I have really been
reluctant to stop using it.
<Ok>
I brush it off in my bucket of siphoned off saltwater during water changes from
time to time, but it does get caked up a little by nature. Could this in and of
itself be one of my Cyano concerns? Just trying to get a handle on this stuff
once and for all.
<Probably not the source, per se, but a contributing factor. You should try to
clean this as you state, more thoroughly and more often. The waste accumulation
can lead to excess nitrates in your system, which in turn could be helping fuel
the Cyano.>
Thanks again, and might see ya around your hometown.
<Anytime, my friend.. Hope you had fun here! -JustinN>

Filtration Methods, reef 1/14/07
Hey guys currently I have a 30 gallon reef aquarium which I admit is
overstocked, and I am in the process of making home for a couple of my fish.
<fishes> and my Nitrates are extremely high about 160ppm, then after a 25%
water change dropped to about 80ppm.
<Still unacceptably high.. More water changes, please! *grin*>
I have started feeding them less, as I was over feeding them no doubt. However
this question mostly refers to filtration.
<Ok>
I have currently a Penguin (bio wheel removed) so carbon filter only, and a
CPR wet dry with poly pad, and ROWAphos.
<How often are you thoroughly rinsing (in throwaway tank water after a water
change!) the Poly Pad? You should make this a regular part of maintenance if it
is not, it will help with your nitrate issue.>
I plan on getting super activated carbon and throwing it in my wet-dry, along
with Purigen, would I still need to keep on the mechanical filter or what would
you recommend I do?
<? ...I'm not completely clear what you're asking here.. Are you asking that
after adding carbon and Purigen to your wet/dry, if you can remove your
hang-on-back filter? If so, you certainly could.>
I also have a CPR protein skimmer. Every filtration device on the tank is rated
to 55gal or 60gal max, so I am getting a lot of filtration right now, I am just
not sure if it is hurting me.
<? Why would it be hurting you? The only possible problem I see is the
utilization of the wet/dry in a reef setting. This is typically not done, for
the reason of the possibility of higher nitrate accumulation. One option here
could be to remove the wet/dry portion in your sump and replace with submersed
live rock rubble, which will likewise act as a biological filter.>
Also, my protein skimmer, after I clean it will up to 2 cups overnight, but
after that I keep the collection cup clean and it just fills maybe a 1/4" per
day... any ideas?
<Perhaps just needs to be fine tuned.>
Thanks for all of your help,
Jason
<Hope my responses serve you well! -JustinN>
Re: Filtration Methods, reef 1/14/07
Hello Again,
So if I understand correctly, I should remove the "BioBale" currently in my
wet/dry and replace it with live rock particulate?... Also, would I then need a
light over my wet/dry? Also, do you know of anyone that might happen to sell
live rock particulate that is large enough not to slip through egg crate? or is
my LFS a best option?
Thanks Again,
Jason
<Mmm, not particulate, then you'd just have a crushed coral-like substrate. Live
rock rubble is the term usually used to describe a collection of smaller broken
bits of live rock, often found at the bottom of shipping boxes from overseas
shippers. A LFS would likely be your best bet, unless you have enough live rock
that you can spare to break some up into smaller pieces with a chisel and
hammer. The idea here is to keep the live rock submersed, and the biota on and
in the rock will act as your nitrifying filtration. Cheers! -JustinN>

<Sorry for the second follow-up here, Jason, but I realized that I missed your
question about lighting. No, lighting is not necessary for live rock rubble
alone. Lighting over your sump would only become necessary if you were to add
macroalgae into the mix. Cheers! -JustinN>
Re: Filtration Methods, reef 1/14/07
Hello again,
Would this be a suitable wet/dry to refugium conversion for my 30 gal reef
tank?, Only problem is the entire refugium area would only be aprox. 1.4
gallons, as my wet dry is only 8" wide.
<It would not necessarily be a refugium conversion, if all you add is the live
rock rubble. The submersed live rock alone will work as your nitrifying
biological filtration, and likely be more effective than the wet/dry was at this
job. Running volume is not as much a concern here.>
I also have a 10 gal aquarium that I could convert, do you know of anywhere I
could get a dimensioned sketch of such thing?
<This may be a better solution, as it will provide more water stability to the
system. Baffling information is posted, available here on WWM, see here:
http://www.wetwebmedia.com/ca/volume_3/cav3i1/Baffles/baffles.htm and
http://www.wetwebmedia.com/refugium.htm for more information on refugium
utilization and baffling.>
Thanks,
Jason
PS: I currently have a hang on back CPR skimmer, so I don't plan on relocating
it.
<No problems here, Jason. Most people only move such things for preference to
see less equipment and more nature. All in personal preference! -JustinN>
Reef Mech. Filtration 12/18/06
Hello, I'm hoping you can guide me in the right direction here concerning
mechanical filtration. My name is Chris and I have a 125g reef ready aggressive
FOWLR. the setup is about 120 lbs of live rock a 30 gallon sump/fuge with 100
micron filter socks, a Berlin turbo protein skimmer and two quiet one 3000
return pumps. My Problem is with tiny floating particulate matter (definitely
not micro bubbles) ,I have two puffers and two triggers
<What species?... too much...>
that chew up the sand and rocks and spit them out, so the tank always looks
cloudy. I was thinking of running a magnum canister filter or a Lifegard modular
filter with the pleated cartridge to remove the suspended particles. which would
be the best choice here?
<This, these would definitely help here>
or do you have any better suggestions?
<A bigger system...>
any advice you have for me here would be greatly appreciated. Thanks for you
time and a great web site. Chris

Mechanical Filtration for a Reef System? -
10/23/06
Hi Bob,
<<Eric with you today...Bob is off on another exciting adventure
abroad>>
I have been looking for quite a while to upgrade my 55 gallon saltwater
tank to a 125 reef ready tank.
<<Neat>>
I am looking at one now, All-Glass Aquarium 125 gallon reef ready, with
a 29 gallon tank for a sump, with a bio-rocker, and an Angstrom UV.
<<Mmm, maintenance hassles aside, I don't personally see the "want" for
UV filtration in a reef tank>>
He said he bought everything at a Local Fish Store, and they sold him
everything that he needed, but shouldn't there be some kind of
mechanical filter system with that setup.
<<Not necessarily...many hobbyists (me included) forgo any "real"
mechanical filtration in reef systems for reasons of detritus buildup
(can easily become problematic) and/or removal of desirable planktonic
life>>
He said he didn't have any and never had any problems. Does that sound
right?
<<Sounds fine to me>>
If there should be what could I do with that in the sump.
<<If you want you can add a filter sock to the end of the drain line in
the sump...just be sure to clean/exchange this a couple times a week to
keep decomposing organic matter from causing problems with water
quality>>
Thanks
<<Regards, EricR>>
Reef Bio Filtration...Keep the Bio-Balls? - 05/15/06
Thanks for all of your help thus far!
<<You're welcome>>
I have one more question.
<<Okay>>
I have a 72 gal reef tank with a new wet/dry filter setup on it. Right now it
has bio balls in it. Do I keep them or remove them?
<<In a reef system with plentiful live rock the bio-balls are unnecessary, and
maybe even to be avoided due to the fact they produce nitrate very
quickly/efficiently but with out the capacity to take the process to the next
level as the live rock is able to do...thus creating an excess of nitrate for
the system to deal with. Best to use live rock/live sand beds for biological
filtration in a nitrate sensitive system like a reef tank...in my opinion>>
Will eliminating them cause a problem or should the live rock take over or
should I keep it the way it is?
<<The live rock will take over. If your system is lightly stocked you can take
the bio-balls away at any time...otherwise, remove half now and half in a bout a
week’s time>>
Along with it I am running a Sea Storm 100.
<<This is great for a FOWLR or FO system...but functions much like the bio-balls
in a reef system>>
Do I remove this also?
<<Would be better to convert it to a carbon reactor or similar>>
I do have 5 medium fish in the tank. What do you recommend?
<<As already stated>>
Thanks!
Chris
<<Quite welcome, EricR>>
Reef Filtration/Selection 4/9/06
G'Day from Australia <And from the USA>
Your web site is exhausting and brilliant, thanks for so much info. <You're
welcome.> My question to you is; there is so much contradicting advise
everywhere from
shops to website's, and I'm a little confused on what type of filtration I
want to use. I know there's all different ways to filter my tank but I just
want the best
way, should I go Berlin style or wet-dry with other means of filtration like
canister for my fully blown reef set up. And why do you say wet- dry are
good for fish only reef systems but not so good for reef systems. <Wet/dry
sumps are great for reef systems minus the bio balls. They offer excellent
gas
exchange and aeration.> I maybe am asking to much but I just want a so
called turn key system that will work the best. One more thing, DSB should
or should not be siphoned, very
contradicting advise from every one. <Providing there is a healthy growth of
micro inverts to keep the sand churned, vacuuming shouldn't be
necessary. Problem here
is that if the population declines, you then have a nitrate factory and a
hydrogen sulphide producer. Very important to keep sand sifting inverts in
systems like
this and monitor population levels. As far as filters, I favor the wet/dry
sump (no bio balls), a good protein
skimmer and a wave making system. Thank you for your time. <You're welcome.

Reef Plumbing/Filtration - 04/09/06
Hello,
<<Howdy>>
I have just switched from a 55 gallon tank to a 90 gallon tank with a 30
gallon sump.
<<Cool!>>
I have four 1-inch bulkheads in my tank and a Mag-Drive 9.5 in my
sump. The guy where I purchased this tank from (Steve, from Elmer's
Aquarium in Monroeville, PA) said this would circulate 1000 GPH.
<<Would be close, yes...assuming no backpressure for the pump to work
against. In reality your flow will be somewhat lessened, determined in
large part by your plumbing configuration.>>
One of my questions is that I only have one bulkhead open because that is
all the pump can handle.
<<Likely your plumbing/head height (all creates backpressure) are severely
restricting output.>>
So this would be 250 gallons GPH, correct?
<<Mmm, not necessarily...but if the single 1" return is handling the flow
without excessive noise, surge, etc., then you are likely pumping 350 gph or
less.>>
Is that enough circulation that I can just leave it alone?
<<Through the sump?...yes...for the tank as a whole?...no. Do supplement
flow in the tank with other methods...perhaps a closed-loop utilizing one or
more of the other bulkheads.>>
Only thing I noticed wrong was one of my elbows coming out of the sump is
dripping once about every 1 to 2 minutes. And it is dripping back into the
sump tank so I am not really worried about it.
<<Ah, okay.>>
The micro bubbles are very minimal. What am I doing wrong?
<<I don't know that you are (doing anything wrong)...I would need more
information about your plumbing configuration to say.>>
My next question is do I need to run a canister filter for this setup?
<<Likely the canister filter isn't 'necessary,' but one could be beneficial
for using chemical media (carbon/Poly-Filter)...if 'maintained/serviced'
properly.>>
I currently have about 50 lbs. of live rock, some corals, 2 yellow tailed
damsels, 1 yellow tang, 1 goby, 2 clown fish, 1 royal Gramma, 1 flame angel,
1 coral beauty, 1 cleaner shrimp along with a cleanup crew. I have read on
this site that canister filters are often misused with tanks running a sump.
<<And also those without...is a maintenance (or neglect of) issue.>>
Would a canister filter help me or hurt me?

Reef Plumbing/Filtration II - 04/10/06
Hello again,
<<Hello>>
Thanks for the speedy reply.
<<You're welcome>>
I still have a few questions about your answers.
<<Ok>>
You talk about back pressure. It is about 4 feet from my pump to the top of
my tank.
<<According to the manufacturer that alone would reduce the output to about
800 gph. Then you have to consider elbows, tees, friction from the pipe
itself, etc., etc..>>
My plumbing comes out of the pump to the top of the sump
tank and goes diagonally to the middle of my stand where it then T's off and
one goes up one side of the tank and the other side of the T goes up the
other side of the tank. So I have 2 3/4-inch pipes going into my tank from
the T.
<<And all adds to head pressure (back pressure to the pump).>>
And I am using 1" flex-pipe coming out of my bulkheads. You also talk about
noise. What kind of noise?
<<Plumbing/water noise...the kind of noise you get from trying to drain too
much water through too small of a throughput (your drains). This typically
will manifest itself as excessive gurgling/surging noises (some folks
describe it as akin to a toilet flushing) and excessive turbulence/bubbles
in your sump.>>
The pump seems to be running fine.
<<And it probably is.>>
Only noise I hear is when I shut the pump off the pipes rattle for about 10
seconds and stop.
<<!?>>
I also have a check-valve and shutoff-valve coming out of the pump.
<<Aha! The check-valve is your problem. Is best to not use these as they
will restrict flow greatly on most non pressure-rated pumps...and the valve
will likely fail on you at some point as well. You should remove the
check-valve and position all inlets/outlets such that your sump will hold
the transient water volume in the event of a power outage.>>
So my last question would be do I need a bigger pump and if so how big do I
need to handle this?
<<If you truly want 1000 gph then yes, you need a bigger pump (how big
depends on whether or not you remove the valve). But if you heed my advice
to remove the check-valve, do that first and then see how your existing pump
performs. Regards, EricR>>
Reef Plumbing/Filtration III - 04/10/06
Once more, Hello!
<<Back at ya!>>
I feel like an idiot asking all these questions but in regards to your
latest remarks about the gargling.
<<No worries mate...am happy to elucidate>>
Yes, I do get that when the water level gets low, is there a way to stop
that?
<<Low where?...the sump? Perhaps you need to extend your drain pipes, or
add 45 or 90 degree ells. Do have a look here for more info on noise
abatement: http://www.wetwebmedia.com/pbnoisefaqs.htm
>>
Next, how many gallons an hour through the sump is suitable for a 90 gallon
aquarium?
<<It's not so much a matter of what's a suitable flow rate for the tank, but
more what's a suitable flow rate for the plumbing/throughputs, as well as
consideration for the size of the sump, and maybe most important of
all...the location of the sump (in other words, do you want to be able to
talk/hear the television over the sounds of the aquarium?). I don't think
you've mentioned the size of your sump in our previous exchanges, but with
four 1" bulkheads for drains you should be able to easily handle the output
from the Mag9.5 (sans check-valve) without undue noise/difficulty. Open up
all the drains and see what happens/how things perform. If you don't wish
to use them all, plug one at a time until you reach that point where the
water starts to overcome the drains.>>
Hopefully this will be the last time I bother you and again, you have been a
great help with your answers.
<<Not a bother my friend. We have a plethora of information about this
subject (and so many others!) on our site...do some keyword searches re and
you'll likely find what you seek and more. But if you don't, please feel
free to ask a question. Regards, EricR>>
Reef Stocking/Filtration - 04/08/06
Hello,
<<Howdy>>
I have a few questions and would appreciate any suggestions you can offer.
<<Alrighty>>
I currently have a 55 gal. reef tank that has been up and running for over 6
months now. I have only 2 fish, a yellow tail damsel and a firefish with
plans for more peaceful fish in the future. I have a 1-inch aragonite bed,
80lbs. of LR, 1 Crocea clam, 1 feather duster, a colt coral, mushrooms,
brown colonial polyps, green star polyps, and a pipe organ coral colony,
plus a number of snails and hermits. I bought all of the corals as frags and
all are growing and appear to be extremely healthy.
<<Ok>>
I know that you aren’t supposed to mix hard and soft corals but I have them
all spread far apart (at least 12” each).
<<Very good...but do employ some carbon/Poly-Filter to help with the
chemical aggression.>>
My first question would be, what is your opinion of my mix. Do you think it
is likely that everyone will be able to live happily in this set up?
<<With proper husbandry/setup/attention to water changes you will likely be
fine.>>
If not, what would you recommend changing or taking out?
<<The clam is probably most at risk here...but with adequate
lighting/placement, good chemical filtration, and frequent water changes you
can make this mix work.>>
For filtration I have LR, a protein skimmer, 3 powerheads, and an emperor
400 hang on power filter which I clean and change carbon on once every week
or two (I don’t know if this filter is a good idea or not for a reef tank,
I’ve gotten mixed reactions).
<<The filter will serve fine with your maintenance schedule...though a small
canister filter (cleaned just as often) would be more efficient/effective.>>
I also do biweekly water changes of about 10% and all of my levels seem to
be well within the parameters. After a lot of research, I still have
questions on filtration. Is my tank poorly set up in this dept.?
<<Poorly?...no>>
I have been thinking of setting up a refugium but am still a little
hesitant.
<<Don't be...can be of great benefit.>>
Do you think that it is absolutely necessary to have one of these or at
least some sort of sump?
<<Not absolute...but again, very helpful.>>
What do you recommend?
<<If you have the capacity...both...else you can 'make do' without.>>
Finally, I was thinking about getting a frogspawn because I want to get a
clown or two and I know that some will host this coral. Given my current set
up is this a terrible idea? If so do you know of any corals that would
blend well with mine that a clown might also host?
<<The clowns don't need a "host," but you can try the frogspawn if you
wish.>>
Thank you so much for any suggestions and advice you can offer.
Nick
<<Quite welcome Nick. Regards, EricR>>
Reef Filtration, Options Galore - 03/17/2006
Great website!
<Thanks Jim. Glad you like it.>
I want to set up a new 65 gallon reef tank. My LFS suggests that all I need for
filtration is an Aquafuge Pro with built-in CPR skimmer for filtration. In
searching the internet I found a CPR Tech page FAQ that indicated that the
Aquafuge PRO was not intended to be the sole filtration system only a
supplement. \
<I agree. Better to have a good skimmer as well that can handle the tank volume.
Look into the AquaC line.>
I am getting ready to make my purchases and want to do everything right the
FIRST time.
<Well that just takes all the "adventure" out of it;)>
Is the Aquafuge set up the way to go?
<A good addition.>
Do I need more filtration and if so what?
<Many options for you but a dedicated skimmer, the fuge (with additional
skimming), and a good bit of LR/LS is all you really need. Here's a good link to
start on
http://www.wetwebmedia.com/reeffilt.htm .>
Thanks in advance!
Jim McDonald
<You're welcome. - Josh>
Re: Reef Filtration, Options Galore - 03/17/2006
One follow up...if the refugium is large enough to support a 100 gallon tank
would I still need the second skimmer?
<I would.>
I only ask because your response mentioned handling of tank volume.
<I like to keep things "function specific". I would plan on the fuge doing the
fuge's job (added benefit of skimmer a bonus), and have a skimmer for the sole
purpose of skimming. Likely much more efficient than a built in skimmer.>
Thanks again.

Reef Set-Up/Filtration 12/28/05
Happy holidays!
<Same to you Ed.>
OK, so the wife and I went into the LFS and were astounded by the coral.
<Amazing isn’t it?>
We thought about a nanocube and did some research and decided that it was not
the way to go.
<Yes they are nice “novelty” items but I find it hard to take them seriously
when they recommend it for marine use without installing a protein skimmer. It
is definitely not for beginners.>
There are only 3 LFS stores in the city selling salt water/marine. In two the
tanks are filthy and in the third we get different advice depending on who we
ask.
<Differing advice in the marine aquarium, no couldn’t be….Seriously though this
is why WWM and other information exists so you can research for yourself and
come to your own logical conclusion.>
We have now spent several hundred dollars on reference books and maybe its too
much information but we're confused.
<Can never have too much.>
We are looking at a 55 g Tenecor marine ready or a 70 g Oceanic reef ready Tech.
<Both are good sizes and reputable companies.>
We would like to keep the tank to 36 inches. We plan to use about 100
lb. of LR and do a 3 inch live sand bed. We plan to do the closed loop
manifold system you recommend.
<Good.>
We'd like to add a sump to hide the heaters, chiller (we are planning MH),
and skimmer and to increase the amount of water.
<Very good.>
Both Tenecor and Oceanic
have recommended sumps including wet/dry filtration.
We have been reading forums in which writers stated that with LR/LS filtration
additional filtration may
actually be detrimental. What is your opinion?
<Bio-media after a period of time tend to accumulate nutrients and it’s just not
as efficient as a breeding grounds for nitrifying bacteria, in either words
except in certain applications…they are becoming less favorable. The surface
area on live rock is more than ample at providing a breeding grounds for
nitrifying bacteria and the bio-media is not necessary. Bio-media is great at
breaking down ammonia and nitrite but not so great with nitrite. Also
macro-algae/microfauna refugiums are of much more benefit to the reef tank. I
would look into these.>
One of the manufacturers recommends an in sump pump. It is my understanding
that we would be better off if the pump were outside the sump. What is your
opinion?
<I prefer “dry” pumps as opposed to wet pumps, they tend not to transfer as much
heat to the water and give you more room in your sump for the equipment and
refugia mentioned above.>
Thanks,
Ed
<Quite welcome, Adam J.>
Major Remodeling (Tank Reconfiguration) 11/16/05
Hey guys great site!
<Thanks for the kind words! Scott F. here today!>
I know you are busy so I will get right to it. I have been running an undergravel system (powered by two power heads) in my 75 g marine tank for years. I also run two (for lack of knowing what to call them) "hang on" filters on the back of the tank that cycle the water through carbon filtration. All has been well until I began to finally get into corals.
<Ahh...the coral bug has bitten...>
I currently have a colony of Xenia, a Pink Bubble Coral, Frogspawn, a couple of Ricordea, and some Green Star Polyps. I also have live rock in my tank as well as some Clownfish, Tangs, a Koran Angel, Large Green Chromis, Cleaner Shrimp, Hermits, and snails
etc. .
My question is this: can I phase out the undergravel system and update to a more "reef friendly" set up. I hate the crushed coral bottom and would love to go to live sand as well as do whatever necessary to give my corals the ideal conditions to grow and spread. Is it possible?
<Well, I would be inclined not to remove the UG filter plate after you stop using it, unless you do plan on removing the
substrate as well (Sounds like you do want to switch substrate, however). I am in favor of setups utilizing sumps for water processing. If it were me, I'd view this as a complete "re-start" of the system, if your intent is to switch over substrate and filtration methodology. The tank will have to go through a new cycling process, just as if it were brand new (which it essentially will be!). BTW, the Koran will get pretty large, and cannot be considered a "coral safe" fish for an indefinite period of time.>
What do I replace it with? How fast should I make the transition?
<Sump-based systems are the way to go, IMO. You'd be wise to set up temporary quarters for your animals as you "remodel" the system. Proceed slowly, and study these types of systems before you make the move. Don't skimp on the equipment, particularly lighting and protein skimming. These items will make a huge difference for you down the line. Good luck! Regards, Scott F.>
It's All On The Site - 11/11/2005
I'm sorry if I'm repeating a question,
<Many, actually.>
but I've looked on the site and I'm still a little confused.
<Much that you find confusing now can be alleviated with time, patience, and research. No worries.>
I'm new at the whole saltwater reef tank thing. I have a freshwater 90 gallon right now that I want to convert to a reef tank soon. But I'm not sure what kind of filtration to use....
<Much, much to learn, here....>
I've heard refugium is the best way to go but.... I'm not really sure how that works... do I need a wet dry to run a refugium??
<No, not necessarily.... start reading.>
<<Not at all. Do what the nice lady says, please.
MH>>
Also.. I know I'll need a protein skimmer but.... what exactly does a protein skimmer do? What is it?
<Removes dissolved organics from the water; again, read.... http://www.wetwebmedia.com/marsetupindex2.htm . Much on skimmers here, also on other filtration methods including refugiums.>
<<Foam fractionation is actually a rather old form of
"chemical" filtration, and has many, many uses, including in some food
production and refinement of certain products. Google "foam
fractionation". MH>>
Also, if I go with the refugium setup, what all do I need to buy to get it up and running?
<Too many possibilities, too much information to impart in a mere email. Start with that link, and get crackin'.... you'll need to form your own opinions on these very subjective questions.>
Thank you for your time. -Kurt
<Wishing you well, -Sabrina> Are Refugiums and Sumps Mandatory? 11/3/05
Greetings,
<Hi Brad!>
Brad B. here. I've been reading a lot on your web site to try an educate myself, answer questions and get ideas. I'm trying to be a good steward
and have a basic question. First, here's my scoop: 46 g bow front marine aquarium / 60 lbs of live reef sand / mix of rock and live rock - a good
coverage of LR but not all that much weight as I chose specimens with good color and surface area but light (save $$) / two Emperor 280s
(fiber media plus activated carbon cartridges) / AquaC Remora skimmer with MaxiJet 1200 / two AquaClear 50s and two AquaClear 30s for
circulation / Coralife 36" with a 96W Actinic, 96W 10,000K white, and two lunar LEDs on a timer - Actinic = 12 hrs and White 10,000K 8
hrs... okay...
Can I expect good success (such as getting/keeping nitrates near zero) with a low fish load - inverts -
corals given the above stated setup without adding a sump or refugium?
<Brad of course it is possible to get away without a refugium or a sump. Though I will say a refugium is in my opinion a great as |
