I don't know what's going on but this is about the 4th time I have had one of my euphyllia coral start to deteriorate and die! I will post a picture of the coral and give all peramiters when I get home from work. I was told it was the nopox I am using so I stopped and it continues to happen and it's randow whe it does happen. Ji had an idea last night that it might be when one of my 3 leather corals shed, but is that possible? I have read that it will kill sos but my tanks is mostly euphyllia and a couple of leathers and LPS. Any advise would help! Please!
