Iodine and HLLE
<Rob, Anthony Calfo here while Bob travels in search of new and undiscovered species of microbreweries>
I am currently treating my purple tang who has HLLE. The tang has a very healthy appetite and all other fish are healthy. I have a 75 gal FO tank operational for about two years and maintain the tank with weekly water changes. No ammonia , nitrite and 15-20 p.p.m. nitrate. I installed a grounding probe just to be on the safe side. I have been adding iodine( 1ml.) per serving, two servings per day, the last week or two along with Selcon when feeding.
Would this constant addition of iodine adversely affect the healthy fish or is it O.K. to keep on using. Or should I alternate iodine like every other feeding?
<without qualifying its efficacy for HLLE, iodine can be used consistently as per the manufacturer's full dose recommendation without fear of overdosing...to an extent. The fish will be safe. Iodine is very reactive and does not stay in solution for more than a few hours unless chelated. It will improve ReDox and is arguably antiseptic. However.. it is a nutrient, and if abused or added to a system without sufficient nutrient export processes (skimming, chemical filtration, etc.) you may stimulate some nuisance algae growth>
Thank You, Rob
<best of luck to you, bud. Anthony>

Dosing Iodine
Hey crew!
I haven't bothered you guys for quite a while....and that fact is bothering me :)
<Not a bother! Really! Scott F. here tonight>
My tank's been set up for three months and I now have a cleaner shrimp. I know they need iodide to molt correctly. I've read on your site faq's that iodide is difficult to test as it escapes the system quickly. All I have is one cleaner shrimp and a blenny in a 55g with 60lbs of LR. Any safe dosing plan I could use for my tank size without using a test kit?
<To be honest with you, I've always subscribed to the theory that Bob offers: If you're going to dose something, be prepared to test for it. To try to use "seat of the pants" dosing for iodine (or any other additive, for that matter) is just not a good idea. Every system uses iodine at a different rate, and it's impossible to generalize how much to dose (well, maybe not impossible- but really difficult!). How much iodine to dose for a couple of small shrimp? Who knows! In my opinion, it's much better to employ frequent small water changes (like 5%-10% twice weekly) to assure that your level of vital elements (iodine included) are replenished. You and your animals will be happier in the long run.>
I have a bottle of reef iodide from Seachem that I've had for 5 years maybe. Think it's still potent?
<I'd contact the manufacturer on that one>
>One more thing, is it ok to have two cleaner shrimp in a 55g together?
<It depends on the type of  cleaner shrimp that you are referring to. Lysmata and Periclimenes shrimps can do fine in groups, but the larger shrimp, such as Stenopus hispidus (the Banded Coral Shrimp) will tear each other to shreds in most cases unless kept in mated pairs. Do check the WetWebMedia.Com site for more information on these shrimp.>
Thanks as always for your fantastic help...Justaguy.
<Thanks for stopping by! Good luck>

I AM CONFUSED BY SUPPLEMENTS ETC..
Bob, Anthony, et al.., thanks for all of your help, I never would have been able to achieve the success I now welcome without all of your help! Several weeks ago I contacted Anthony regarding what type of lighting addition to use, I must say that his response guided me toward the purchase of an additional 175W MH, one will be 10,000k one 20,000k as Bob states in his book (this is on
a 55 so I have some heat to get rid of!!!)
<no worries... a comparable fluorescent light system would need to be so close to the water that you'd have the same heat issues. All are tempered by a good open canopy and inexpensive muffin fans to run>
My question is this, I have been following the GARF method of supplements and have had a bit of success, but all of the reading I have done seems to indicate that IODIDE dosing is very important,
<agreed... and I favor small daily doses while Bob likes weekly>
particularly to certain corals. Are there any adverse affects to other species such as Acros from high levels?
<you'd have to define high levels. I suspect that reasonable doses (stock solutions listed in Sprung's book, my coral prop book, etc... are no trouble at all. And iodine is unfortunately removed from any system VERY fast... about 6 hours (hence my daily dose rec' for fast coral growth>
I use SeaChem, should I stay with the manufacturers recommendation or dose heavier?
<Unless you are farming corals, stick with mfg dose and break it down daily IMO>
Also, my temp fluctuates 3 degrees per day (79 at night to 82 w/ current halide) is this too much of   a fluctuation?
<a bit much for fishes (Ich). Exhaust lights better by day and add a second heater for stability. Set temp to 82 F even>

Iodine use
Hi
I have constructed a 500 gallon system for cryptic filter feeders.  
There is an algae scrubber and a skimmer.  I will be importing tunicates, sponges, Dendronephthya, file clams... water movement is via a fast current generated by a large water lift into the scrubber, and a Wave2K.  The system has three tanks and two refugia, so that I can isolate and experiment.
     There is an automatic top off unit for RO water.  My question is- is there any problem (other than the controversies about using iodine at all)  with putting the iodine in the freshwater top off tank? << I don't there is a problem, but I would probably dose into the tank. >> This would allow continuous infusion.  Also, if no problem, can I also add two part alkalinity/calcium supplement to the same reserve with no interactions (i.e. does iodine precipitate on calcium carbonate)? << Well you can't add the two parts of a two part solution together.  You could add buffer to your RO water, or add calcium, but you can't add both.  Soooo, I would suggest dosing iodine and calcium, and adding your buffer to your RO water.  I wouldn't mix calcium or iodine in, because you don't really know what reactions may take place. >>
Thank you so much!

Lugol's Solution   1/30/06 wow bob it was so nice to meet you and talk to you here in Irving TX  today. I really enjoyed your lecture. ok can you give me the name of that iodine again, you said 10 drops in a 75 gallon tank, this will not harm corals or fish is that correct. <Correct, and name above> am the one that was telling you about my rose bubble tip anemones not being big like they use to be. you also said they were in competition with all my leather corals correct. wow what a day it was to hear all you speakers speak. ill have to do some research and find some of your books. thanks again for  an unforgettable day ill remember this for along time. Mickey white <Pleased to meet you again Mickey! Bob Fenner>

Here is a pic of these RBTA   1/30/06 well what do you think. they have turned a pink color and been right their for several months, they don't get big like they use to, will try the iodine you suggested. thanks <Mmm, let's re-state... the Iodine/ide will help, as would using activated carbon (once a month pouch, leaving in for two months), and improving the lighting (the MH you mentioned, switching out the two white PCs)... the Sarcophyton/Leather is really too much here... and you would do well to "frag" it... or cut it in half, give half away. Cheers, Bob Fenner> Mickey white

Do appear dyed eh? Color loss from simple dilution/division?

Re: Lugol's Use ok ill get some Lugol's solution this week,10 drops for a 75 gallon tank, should I do this ever so often or just one time only. thanks  bob Mickey white <Best to use in concert with your water change activity... every week or two when you change water. Same dosage. If you want to use more frequently, you need to get/use a test kit for iodine. Please read over this area: http://wetwebmedia.com/iodfaqs.htm Bob Fenner>

Iodine and crabs 6/3/06
Thanks, how do I dose with iodine, in water or feed, dose rate, what does iodine actually do?
<Iodine assists in the molting process, it is added to the water.  Dosing rates vary based on the brand, so follow the directions on the bottle.  It is available through most LFS or on-line.>
