Have you tested parameters? Heater is OK? No pests? Angry neighbors?

Could something have stung it to cause the rtn?

I think it's hard to say. In some, probably most, it's just a single bleach out. If you haven't yanked the colony I would. Keep an eye on the frags, if you fragged it early in the rtn stage you may have a decent chance to save them. Sometimes they'll rtn as well, it's weird. I'm pretty amazed how hardy most sps are, but even with that said, they are a touchy, if not a frustrating bunch.
I would just make sure your using fresh carbon, dosing magnesium can help. It's just sit and wait to see if anything else happens, especially to any sps that were close by. Good luck.
