Interesting that one coral "browned out" while others were dying off.

Browning is a typical sign of high nutrients, isn't it?
Perhaps the mucus secretion from your LPS and soft corals had increased suddenly for some reason leading to a high level of dissolved organics, plus some added chemical warfare happening at the same time.

Were you adding any corals shortly before that "event" or fragging anything?
