I know this is crazy, and you will all probably disagree with me, but I'm posting this to see if anyone has any other ideas.
I have a 150 gal tank with a 27" depth, and a 2" black substrate, running for about 8 months. I have 3 150W MH lights, with 8 T5 actinics and 6 LED moonlights. Water parameters are not only good, they are perfect. Temp is 78 with lights out, 80 just before MH goes off. Here's how some of my livestock are acting.
Ricordea. Had them on my old 110 with PC lights, thriving with deep colors and multiplying. Now have them on a flat piece of rock on the substrate at the bottom, and they are not as open, paler in color, and not multiplying. Now have them screened from the light with 4 layers, and they are more open and have more color.
Green Stylophora. According to the literaure, they like strong light, strong flow, right? So, I had them at about 9" depth directly under one MH and in strong flow. Well, they bleached after 2 weeks. Now have it under the same 4 layers of screen as the Ricordea. and they are recovering.
Branching acro. Again, strong light and flow lover. Polyps were out in the daytime when I first got it. It's is not bleached, but the polyps now only come out under the actinics and in the dark. Otherwise, it seem to be growing, but it's turning into a nocturnal coral.
Blastomussa. On a flat rock in the substrate, moderate light requiring according to the literature, and it's only doing ho-hum.
Eagle eye zoa. Only half are open under the MH, all are open under the actinics, half are open in the moonlights.
I have mushrooms in shade under overhangs, and those are doing very well. In the open under the lights, they are barely open.
What's confusing me is that other corals seem to be doing good. An Acro tennui, a Monti cap, a green Millepora, all about 8"-10" under the MH, and they are all thriving and visibly growing.
