Torch coral dying.
Can someone please give some advice on this. All of my parameters seem good now. Salinity was low for a bit due to an uncalibrated refractometer. I switched from 6 X t5ho lighting over to two ai sol blue fixtures. I have slowly turned the fixtures up starting at 35 percent on all three channels to 65 w and 55 for each blue. I don't know if it needs more light. Less light. Or if it is altogether unrelated. Everything else in my tank is doing good except for snails and a tube worm which are being harassed by a black brittle star I can't catch. Any advice would be awesome.
