I’m continue to fight the summer tank crisis and still not sure whats going on with my tank - all params looks fine, some micros are low but it shouldn’t cause that much distress imho. Its been two month and my tank is not recovering at all - all corals are stressed and no signs of even slight improvement. Ricordias and mushrooms are not expanding, acans gone, chalices gone, most of SPS don’t show any polyp extension. Even zoas are stressed! I tried big water changes, no water changes, feedings, no feedings... Lots of algae on dead coral’s tissue, lots of aptasia and vermetid snails taking place of corals. Got rid of several big colonies, cut dead parts of other’s.
I’m out of ideas what to do - the last thought is that it might be some kind of chemical warfare since my tank is quite small. Any idea where to look and what to try?
