coral help..please

about a week ago we up graded our filter and it was more powerful then expected, it blew bubbles down and a strong current and damaged my hammer and frogspawn, the hammer has a few pieces on 2 of its heads that are damaged and it has only came half way out since, and the same as my frogspawn, a few of the lower heads are dark and sad not quite comming halfway out since . im worried about it dont want it to die, the top heads are full , open and bright, could it be stressed about the light as it had to be moved lower in the tank? ive had it about 2 months before this happen and its grown and done very until this happened.

Im not 100% on it, but we had the same problem, and the ones that werent looking so good didnt come back for us, but....however, we had new heads appear after 2 weeks or so....Post a pic if you can and I will have a peek...

i cant figure out how to post pics...

Do you have a photobucket account?..Its free

youll need to copy and put it together as im new ..not allowed external links.. the coral has improved since i tilted it a bit more but 2-4 heads are still sad looking

bad pics as i disterbed the sandbed earlier so its all cloudy..

ok had a peek...yeah thats kinda what mine looked like......Do they look like slimey or something close?...Mine went like mush then never came bk except for the new heads that formed there

their just dark and kinda shrunk, just barly comming out, i also noticed one one of the healthy heads the bottem psrt is is large there a dark ring like its being ristricted and the tops are smaller and dark on a few the tops have disapeared/fallen off, could my damsel have done this or is this something it dose when stressed? im in the process of getting thing together to take them out and start a 40 gall reef tank and have the 55 a fish only
