I will tell you this, I have a bacterial issue (I assume could be some other micro-organism) in my tank at the moment, at the edges of sps or any compromised spots I am seeing bacterial necrosis, really slowly the tissue gets eaten and is replaced by a brown mulm-like deposit. I am really stumped as to how to stop it on the undippable colonies I have. So I think there other viable forms of necrosis other than light and parameter based issues.

Keep the big 3 steady is number 1, to high or to low nitrates can be a big factor. A couple tanks back I was using a non food grade trashcan to mix my water, it took me forever to figure out where the problem was coming from, so every water change I was hurting more than helping. During that time every sps I put in the tank would RTN within 3-4 days. If your nitrates, phosphate, and big 3 are good sps should thrive.

What was the cause of the non food grade can? I am using a plastic storage been. Probably no food grade either.

I have coralline growing crazy in my tank and I just lost 2 sps frags. Got water back from triton too and nothing tested out of the ordinary.

Did your sps make it Rev? Did you figure out what’s the cause?

The cause of STN is a bacteria infection that moves fast across a stressed coral .
