Favia health?

[Blitz06]

Hey all, so I’ve had this favia colony for a few months now. When i first put it in the tank I had moved it from the spot it’s in now to the sand bed on the left side. I have a fine sand and I started noticing some tissue recession. About a week ago I moved it back to its original location. I took this picture in the morning and you can see some white on its skin. I do see it’s feeding tentacles at night which I know is a good sign. Have a look and any feedback would be greatly appreciated. Just wondering if it looks healthy.

It sounds like the sand was irritating it, I would think you should see improvement in a couple weeks now that its not in the sand.
