Paly's not opening?

[liquidglass]

My green paly's that I have had for a long time have not been opening now for some reason the last two week's or so. My Water parameters are great and the rest of my corals are doing great. I can't see anything munching on them?
Any suggestions?

All is fine with water, my Alk is 9.5.

have you changed your lighting recently??

I did move it about a month ago or more from mt 70g (250w) to my 180g (400w)
But put it on the bottom of the tank. It was open for a while at first. Maybe it got burned from the light? I saw that on the link at the top of the page for possible reasons. If this is the case will it come back?
Thanks everyone,

Usually the light will bleach your polyps, not burn them.
