Orange plate coral not looking normal

[Scatcat]

My orange plate coral is not looking like itself when I say this it's hard to pinpoint the problem. This morning it was swollen looking for some reason it was pushed up to the coral next to it so I moved it and now it doen't look swollen anymore. But I noticed it's mouth was open some today and now it's closed. Nitrates 0 salinity 1.022 no ammonia everything else is normal acting. I'm currently in the process of trying to raise my calcium using purple up. Is he dieing if so is this going to be a problem?

What is purple up? I havent heard of that product before. Any way of taking a photo of the coral?

PurpleUp is a additive to help your corilline sp? algae. I can take picture but I don't have digital it will be a few days for me to develop it. It's like a calcium additive.
