:shock: Ouch that's quite the bloom! I feel for ya Christy, that's gotta hurt!
I would recomend removing all corals and cleaning them free of as much alage as possible. Quaritine all corals in a seperate tank while you deal with this if possible, as your corals look like they are getting totally choked out by all that hair and slime. Then I would start from the bottom and work your way up, look at water quality(top up or water change h20), overdosing of any additives, any sudden deaths within the reef, and so on and so on. You may find that it could turn out to be something simple before something complex. (Just my 2cents) Goodluck :!:
