Yumas shriveling up and bleaching

[ghost]

I have had my yumas for several months now and now just about all of them are shriveling up to hardly anything and some of my orange yumas are bleaching. I did have 2 of my t5's go out, but they are in the back of the tank and don't really effect the Yumas since they are in the front of the tank. Salinity is good and parameters are in check!!!! HELP!!

High sality was the culprit when this happened to me, hope ya get it figured soon, those are great corals
