My Zoas on this rock look like they are all dying. I'll post a before and after pic. I noticed a white mold looking stuff in and around a couple heads, also one of my hermits is all of a sudden in there picking around. Only thing that has changed is my lighting. I made a big jump from T5 two bulb to a T5 eight bulb HO. The eight bulb has older lights, but I did not acclimate by cutting the light time down. I didn't even think of it til 2in10 mentioned it in a different post. Thoughts please.. FYI all my other corals look fine if not doing better or is it a matter of time before they start going downhill?
