Thanks for the replies! I gave my readings up above. As far a lights, I have 1 175 MH - 12000K, 1 15 watt flour. 5000K, and 1 - 15 watt actinic flour. I have tried them away from the MH and moved them different places. At first with moderate flow, then low flow. Nothing seems to work.
I have 2 big bubble corals, 1 scolymia coral, assorted mushrooms, a red gorgonian, coral banded shrimp, snails, scarlet hermits, button polyps, riccordia mushrooms. All seem to be doing well except for the leathers.
