I just moved all the corals to the sand bed of the big tank (lighting much more intense with the halides vs. T5s). Really didnt like how things were looking. I really believe everything was going to die, could have been wrong.
Hate to put anything stressed or sick in the big tank, but as no isolation tank currently, had no choice. Big tank is a 214gal with 60 gal fuge/sump that has been stable and healthy for long time. I think it could handle it. Even moved the RBTA, but left the fish behind, they dont seem bothered by the mystery crash.

I very much appreciate all the comments. I have been at fish long time, but new to reefs a little over a year. I am a perfectionist and struggle with failure.........
