Hi,
My name is Hans-Werner Balling and I am doing R&D at Tropic Marin. I also have developed the All-For-Reef.
Iodine is a very important trace element for coral growth, coloration and polyp extension.
Low iodine concentrations slow coral growth, make the brown color fade to a pale grey-beige and especially gorogonians may show reduced or no polyp extension at all.
High iodine concentrations make the corals dark brown but this depends from nitrogen supply also. Iodine is important for the adaptation of coral and zooxanthellae pigmentation, both, photosynthetic pigmentation of the zooxanthellae and fluorescent pigmentation of the coral polyps.
Unfortunately iodine consumption in a tank is neither connected to calcium nor to alkalinity consumption. Rather iodine consumption is dominated by gorgonians and sponges but iodine concentration also affects other corals like leather corals, Heliopora, SPS and LPS, in short quite all corals.
In a thread about ICP analysis I found a post that iodine dosing with our A- Elements and maybe also with All-For-Reef may be rather on the low side. In my opinion slightly high iodine concentrations may be better than low concentrations. I already wondered whether we should increase iodine concentrations in A- Elements and especially in All-For-Reef for some time.
To get clarity about this question I wanted to ask you, what your experiences are. Is iodine concentration of All-For-Reef rather on the low side or exactly right? Which concentrations do you get back from ICP-analysis, 60 ppb or more or less? Do you find any of the descriped symptoms of low iodine concentration in your tank?
Thanks for your contribution.
