Caused by what?

I don't know about LPS. But have heard with Zoas that's how they spread out to other places. So I've been told, and in my tank I agree. I have polyps popping up all by themselves in some areas.

is anything picking at the coral?

[Ido1]

Nope,nothing.
I have to say,all my other LPS are fine and in excellent shape.
This is the only coral with that problem.
The polyps in the edges is actually shrink a little bit,peel off and detach,until there is nothing left.

I'll try move it to another place.
It's a Favia.

flow - 3 pumps of 1250 GPH each one + 1 double pump of 3000 GPH.
the pumps are Sunsun (similar to koralia).
water parameters:
salinity - 1.025
Calcium - 450
Alk - 9
