Coral metabolism vs. light par

[Canadian]

Steve,

Fauna Marin isn't equivalent to GHL Profilux - they just happen to be distributed by the same North American distributor (Aqua Digital). So you can criticize Fauna all you want without criticizing GHL.

And I agree about the pics being an add but they were the only ones I knew of off the top of my head that included underwater and out of water pictures of SPS grown under T5s.

the question wasn't about the helth, it was does light affect the metabalism of the coral. and from everything I have read on corals the only thing that directly affects the metabalism of a coral is temp. but having said that if you can find something that states other things let me know as I am always interestd on reading stuff like that on corals.

ah good to know I thought they were one and the same. but I am not critisizing, just stating that I cannot accept a company's add as proof. thats why we have places like consumers reports and such

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.
