It was encrusting onto my rocks… and as some may remember I was battling a day of 92* temp 3 weeks ago. Everything except my SPS survived, and the hydno looked like it was doing well. Polyps extending, etc. a week ago, it started slowly melting and has been getting worse. I did a 10 gal water change a few days ago on a 32 bio cube. Still no help.
What’s wrong?
