I placed a meteor shower cyphastrea at the bottom of my tank (90-110 PAR). The polyps that are in the 90-100 PAR region stay fairly extended (not nearly as much as they used to be), but there is a 1-inch area on top where the light is about 110 PAR, I have lost a few polyps and the others remain tightly closed. I also recently extended my photoperiod by an hour.
I also bought a red monti-cap frag that will eventually help shade it, but that will take time. Do you think the polyp loss is light related? There is no tissue loss, just polyps in the one location.
Here are before and after pictures:
