I've been battling this for many months. I'm at the point I'm ready to scrap it and go to oscars but I do like my tank and the wife likes "marlin" the clown fish.
90 gallon with sump. 120g total volume. Big gyre keeps things stirred up.
Skimmer is undersized yet constantly pulls out dark skimmate and I only feed the two fishevery 3 days.
Lights are Chinese leds.
RODI (0tds) used with reef crystals.
I've tried large water changes, gfo, carbon, phosguard. peroxide dips and scrubbing rocks daily. I have siphoned ssb till it runs clear. Turbos and Cerritos will eat it but can't keep up. When I had a yellow tang it must've kept it mowed down. Problem resurface shortly after its demise. Black outs have little effect.
Only sps is encrusting monti which is spreading with good polyp extension but minimal color
LPS survive but grow very slowly
Corals grow slowly if at all and lack color since I'm petrified to feed or dose acro power.
GSP grows excellent but zoas not so lucky which makes me think it's less of a nutrient issue but with this issue I obviously am not an expert on this stuff
Tank is nearly 2years old
