did you acclimate the coral to light at all? because you have upgraded from a very weak light to a very good light and if the coral was used to trying to get everything it could from the pc lights it could be in shock from the new light source.

How are your other parameters? Nitrates, pH?

Light shock, definately. Also, if it was me I'd raise the salinity up to about 1.026

Just a little update on my hammers. Moved them 8-10 inches down in tank and boom they opened right up. Back to the size of a softball. Thanks alot everyone on the light shock info.
