Sorry to hear that Angel... Unfortunatly in my experiance once this starts you can't stop it no matter what you try. I have had other lps do the same thing. There are so many different reasons why that one never seems to fit the senerio. One day it's fine the next it's gone. I had every LPS in my tank go this way about 2 years ago starting with the really nice red and grean open brain that was almost dinner plate size! I also have seen the same thing happen to Elegance coral so I stopped buying them.
It really is sad to cuz without a reason you may never know what happened especialy if the rest of the tank is doing well. Sorry not much help for it.
