Effects of Iodine in SPS?

[Randy Holmes-Farley]

At the end what did you see? To dose iodine has a real effect on sps color?

Unfortunately, I'm not sure we will find out since he has not been on in more than a year.

I've not seen any evidence that typical SPS corals benefit from supplemental iodide and/or iodate (the forms of iodine in seawater).

But if you are having issues, it is a fine experiment to try dosing iodide and see what happens. It is very unlikely to hurt anything by dosing it. I dosed it for many years, before stopping because I saw no apparent benefit.

Hello Randy

Well, yes, depending on how much of each was added.

I don't do the ICP test. So.. My goal is to add them under dosed every weekend or 10 days during they water Change...

Potassium may not deplete at all, so I would not dose it without testing.

The others could be dosed in amounts that folks like Tropic Marin think are suitable for average tanks with their supplements, and I’ve not heard of folks overdosing those using that method (e.g., TM A and K).
