It seems that my LRs are turning black .. it looks like some kind of algae since the blue legs are eating them.
I have 120W of light. I have cut that down to 80W/day since I saw the black algae. My NH3=0; NO2=0 and NO3=5ppm. I have yellow tang, 3 damsels, 1 clown abd 1 royal gramma, along with 1 shrimp, 1 emerald crab, 100 blue legs.
My Ca=390, and no PO4 since I use RO water. I have my lights turned on for about 10 to 12 hours a day.
I also a couple of soft corals and LPS.
I have diatomic a month ago and is not almost completely one. There are also one or two patches of red, which I believe is cyano algae.
What can be causing black algae.
