Elizabeth94 Posted February 23, 2020 Share Posted February 23, 2020 I believe what you have here is a pretty bleached alveopora. Your hammer also looks like it is receding (you shouldn’t see the pointy skeleton). It is most likely a water quality issue, which the cyano also shows. Are you using RODI water? Not sure if it is just out of view, but I don’t see any powerheads either. Do you have anything more than just the return? Flow and water quality are my first culprits. Quote Link to comment
