Coral Information and Help

Afternoon all,

I bought a hammer yesterday from my local lfs which was absolutly stunning, got it home did the usual float bag and drip feed for 2 hours then placed it in my tank. Up to now non of the heads have come out and a few tips I have seen floating around in the tank. My sg was a little high yesterday at 1.030 so too was my mag and Cal. I have just done a 25% water change using RO to lower the salt level which has now been achieved but I am at a loss as to why my hammer is...
