I have a 220 gallon reef and having an issue that I can't figure out. i have frog spawn, hammers, and a few torch corals.. the skeletons of my torch seems to be dissolving.. eroding.. being eaten away.. something is killing it quickly. I have checked all my parameters and everything seems fine..
PH: 8.15
Ca-490
KH - 8.6
Alk - 3.09

Anyway.. any help would be appreciated.
Thanks.
