my fish guy told me to just add it once a week. not to worry about testing it. I just did a 30 gal water change. everything looks fine but i guess time shall tell. I have all the reg, test kit but none of the exspencive ones i.e iodine and such.. is it worth the money i only started corals like 3 months ago but have had fish only for bout 4-5 yrs now.

Your fish guy is giving you bad advice. 1 - there are very few animals that benefit from Iodine dosing, probably nothing in your tank will benefit and 2 - Iodine is a poison and levels only slightly above normal can kill.

If it were me I would do as large a water change as I could handle.
Bang can you give me the details or difference between Iodine and Iodide in the aquarium.....Don't the test kits actually detect the wrong one giving a false or inaccurate reading??? I can't remember

there are actually three "flavors" of Iodine, Molecular Iodine (avoid this - never dose it), Iodide, and Iodate. Iodide doesn't last long in our hobbiest aquariums because algae sequesters it quickly. It is thought this helps the algae by making it taste bad and therefore is slightly less likely to be eaten. If you love algae then this is the chemical to dose in your tank. Iodate is what makes up most of the free iodine in natural seawater. As far as testing, I would only use the Salifert test as most other tests do not register Iodate and this can result in overdosing.
Of the animals that actually need Iodine to grow, they typically need to eat it, not absorb it from the water column. Most saltwater food is sufficient in Iodine.

Not being a jerk GeoJ, but you can't believe everything printed, and are your referring to Brightwell which manufactures additives?

+1 Agree....Iodine !!!!!!!!!! Never dose unless you test for it....
Test for Iodine???? Why would you test for Iodine..It would all depend on the size of your tank, if you have a small unit and you feel you over dosed and your livestock are acting abnormal add carbon and than do a water change..if you have a Large tank and i'm talking over 100 gallons unless you put the whole bottle in your tank than don't worry about it..you do not have to test for Iodine...also would depend on your livestock in the tank they will use it up via algae ...I have a 125 gallon fully stocked fish and corals..and I dose my tank every other day with a teaspoon of Iodine..and in 4 years have never tested for Iodine..and when I do a water change I wait a few days and than start dosing again with iodine...I have never heard of anyone testing for Iodine..must be for people that don't know what they are doing...

Or the exact opposite
. As far as adding any supplement to your tank, I've always been of the opinion, of never do it, without the ability to test for it. And for iodine specifically, never do it (basic water changes will supply sufficient iodine for 99% of aquariums) without a specific reason to due so (loaded with softies or gorgonians) As stated up thread, depending on the level, iodine could very well be a toxin. Something along the lines of what some people commonly dip corals in, to avoid parasites. Why anyone would want levels of their iodine, is basically to have a figure their tanks are running at. If you can't grasp that, I'm not sure exactly where to go from here.... I wasn't sure many people enjoy 'flying blind.'

When my 125gal was running strong with softies and photosynthetic gorgonians, I dosed 16 drops of Lugols weekly, and tested via Seachem test kits. I definitely did notice via those tests, when my levels were low, if I skipped dosing or something to cause it. I was under the impression that not only algae used up iodide, but it was the corals and gorgonians that consumed also iodide, rather then iodine. Will do further research on iodate consumption...

Indy sounds like your sitting on a time bomb. Not even going to debate with such haphazard info!!!! Amazing... Why test for anything?:flame:
