Whats happening to my corals?

That particular picture is from January or February of last year I believe.

Thank you Ryan for fixing the picture!

Chat, I would frag them if I could, but it just seems to happen so fast that I can't even catch it happening in the process.

Knock on wood, but I think whatever is happening is stabilizing. I haven't had any problems since Friday evening.

Ironically the only corals that have RTNed green like the picture, came from a certain LFS back before I stopped shopping there.
