You realize that Potassium iodide is iodine? Are you dosing iodine twice then? Are you testing for iodine, iron, and strontium? If not, how do you decide how much to dose? FWIW, there does not exist a hobby grade test kit that is particularly accurate for either iodine or iron.

Why don't you try out a few of the ZEO products? I have noticed a huge difference in my corals, and I think it would be mainly attributed to ZEOvit Pohl's Coral Vitalizer.

What's your temp at? I've always found my corals are more colorful if I keep the temp below 80. Tough in the summer though...

I'm having the same problem with some of my corals, tagging along

Doug, is it this one? I recognised the rock formation, man its grown a lot. This is not from the same nana that I have, you have one of Greg's. Mine was purchased with a bit more color than yours, but has since lost most of it.

Myka, I do realize that the Pottasium is bonded with iodine. My LPS are loving every last drop of it too. The reason I'm dosing iodine, strontium etc etc is because they are good for my corals and fish. I don't test for them, I add them based on the instructions noted on the bottle, the same as many other aquarists. My temperature hovers around 76.5 to 78.0 on average, but did jumo to 80 during our May heat wave. The tank is in my basement, and the house has AC so it likely wont jump over 80.
