See pics below. The color seems to disappear when the lights go out. Acro tips are turning brown, and other SPS doesn’t do well. Tank is 10 months old. I have a 25w UV running at a low flow, closest guess is around 400gph.
Dosing: AFR, H2O2, and NP Bacto Balance
NO3 10
PO4 .08
Temp 77°
Salinity 34ppt
ALK 9.1
pH 8.1-8.3 ish
Salicate might be 0.1…definitely not more though. The sample is really light
It’s just a coloration on the sand. Nothing is there to siphon up.
