Iodine Question...

It is commonly know that invert get all the Iodine that they require from the water column and from food. After having a debate about this issue on another site, i did quite a bit of research into iodine in the reef tank and it is a documented fact that no organism in the tank has "ever" had an extensive experiment done to it with one exception, and that exception is Macro Alage ( Chaeto and Caulerpa ).

I am not denying that corals can use Iodine for tissue repair, but still, there is no documented facts that proves we have too. What is documented is that by carrying out regular water changes will replenish Iodien in the water column..

Pretty much all the marine organisms we keep get their necessary iodine from foods. In fact, the study the prompted the addition of iodine into aquariums was based on dietary iodine (not iodine in the water column). Few things uptake it directly from the water column. As for the things that do, it is hard to say whether or not it is even necessary or beneficial. Crustaceans sequester iodine when molting to get RID of it, not to use it. It is their way of eliminating the substance from their systems. Adding it directly to the water column is very uncontrollable. The reasons people see an increase in molting upon addition is because they are trying to eliminate more of it, not because it is helping them molt 'better' or 'more.' agreeing with atnixon, stick to waterchanges and proper foods.
 
the way i look at it is if you have a ton of soft corals then you should be dosing a vey small amount of iodine, if you have a heavy reef tank you may run out of iodine before a waterchange takes place and i wouldnt want to short my corals on anything they want to thrive. But overall its personal preferance, one guy could say i always use this and it makes my tank better, but the next guy could say whats that, ive never heard of it?
