I'm keeping acropora, clams and all sorts in my tank that are healthy my parameters have been stable for the past few months other than a bit of copper and birdsnest corals just bleach and die on me! Had a smaller colony die and now my larger one is starting to! Could it be lighting? I had 2 kessil a500x on a 3ft cube always 100% up untill the other day. But lps are under like 250 - 300 par and doing great


. It'd be good to know what could have caused it though although I have read that it can be a delayed reaction so maybe it's not even from my params now
