Sounds like your corals are starving from not enough light. Your story reminds me of my sps issues last year. My acros would survive a couple weeks to a couple months but they would slowly wither away and then stn/rtn. I had a single hydra 52 hd over my 50 gallon cube at 50-60% power, and many told me that was too much light. I was also chasing low nutrients with nopox and gfo because ppl said 20 no3 is too high, get it down below 5 or 0.15 po4 is too high get below 0.03. I bought a par meter and found out that my settings were producing less than 200 par at the top. Now I have 2 hydra 52 HD’s delivering 600 par at top and 350 on the sandbed, no gfo, no nopox, no skimmer and a 40 acros growing everyday.
Sounds like you need waaaaay more light, but don’t do it over night or even a week. You should raise them a watt or 2 per week. How many watts are they set to now?
