Set up a 125gallon last may. 30 gal sump with skimmer and calcium reactor. 2X150W MH 14K and 4X54 T5s. Temp 78-81. Calcium ~420 dkH 11 Nitrate <5 Tank was stocked with 2 angels (flame and flameback), yellow tang, six line, midas blenny, diamond goby, maroon clown, 2 anthias. Coral: brain, frogspawn, plate, large montipora, duncan, green birds nest, various shrooms and palys. Last September all fish with the exception of the two angels died in a two week period. The only symptoms were the fish's color faded and they all had white/cloudy eyes and they all appeared to be breathing rapidly. Once these symptoms set in the fish were dead within 3 days. I waited 4 weeks and threw in a few damsels-all died (except the two angels) within 3 weeks with the same symptoms. I waited 3 months and slowly started to add some more fish. All was going well until last week. The 2 PJ cardinals, royal gramma and yellow tang that I had added over the last 2 months all died in a one week period. I am lost. I do not know how to proceed. Throughout this ordeal my coral have done great. Based on this I do not think water chemistry/contamination is the problem. I am pretty sure that this must be bacterial/viral in nature however I have no idea how to identify. Additionally I can not understand why the two angels are happy and health. Any suggestions???
