Sorry to hear about your hammer coral.

I had some trouble with my hammer a little while ago. I moved him to very low flow zone in the back of my tank, and it seemed to help him.

Hopefully your guy bounces back too. Good luck.

Phosphates being .88 could be your issue. I find LPS do well from .03 to .12
Have you tried running GFO to bring them down?

Phosphates are too high. It's going to take some time for that high of a level to come down.. so be patient
