What's wrong with my palys

[wdbill]

I have 37 gallon cube and I have something wrong with my palys. Some of them have white on them and just about all of them the edges of them are curled over. My lfs told me it could be the temperature. The tank runs a little warm I would say in 81 to 83 range. They were doing fine a little bit ago. My lfs had a used 1/15 hp chiller for $175

I thought it was a good price so now I have a chiller! I have other corals they seem to be doing fine
