Ok, since once again the search function is down, I'll just ask this question. I have a 375g (96x30x30) mixed reef running 4x250w MH (10K) and 4x96w PC(actinic), all corals and clams are growing well, but a large portion of the corals are adapting a tanish coloring. Clams and RTA are still bright along with a several red mushrooms, but a large portion of mushrooms, leathers and torch corals are developing the tan coloration. Would changing the light spectrums help brighten the colors or could it be some other factor. Water parameters all check good, except phosphates are higher than I'd like, but I'm working on that.
