My calcium is a bit low at 320 because of the sps corals I had I'm dosing more calcium to the tank nitrates are at 1 ppm,phosphates 0.01 cause of nopox, I'm feeding it more with reef roids alk is a bit high cause of low calcium at 12, magnesium 1420 I kept moving it alot so maybe that caused the stress, right now I left it on the sand bed, when it was on rocks the flow made it fell on the sand and may have irritated the flesh, I have 180 par led lights and a fliter with 300gph and skimmer that provides most of the flow
