A little update I have dipped the coral and raised all my parameters to what they should be for a reef tank and it has been coming back lost a few polyps but most has come back
Excellent!! Mine took more than a month to fully recover, but it did, and at one point looked every bit as bad as yours. Just keep things stable, and fingers crossed!
Any update on this thread? Did your wall hammer recover? I have a wall hammer coral and it's going through the same thing. I'm going to try and dip it today and see if that helps it. All parameters are where they need to be but obviously something is wrong I will also try and move it to a lower flow and less light area of my tank.
