I just got back from a 2 week trip and once I came back I noticed my torch coral receded heavily and some white hair/film covering the skeleton near the polyps.
All my other corals are doing pretty good, except for some new acropora frags I had added a week prior to leaving as testers. 3 of them have bleached considerably, although the 4 others seem to be doing fine. I was expecting some of them to die off, considering I am still new to sps and dialing in the tank flow and lighting. The alk, mag and calcium all dropped a bit (8 to 7, 1300 to 1230, 450 to 415) since my dosing pump wasn't dialed in prior to leaving but I wanted to try to maintain the parameters without overdosing while I was gone, so I aimed on the safe side and underdosed a little.
What should I do to try and save it?
