Epoxy SPS trays...?
 

I just got some sps frags, do I need epoxy them on the rock right way? Or just wait for couple weeks to let them settle down a litter bit? Some frags always fall down from the rocks, but I'm not sure where to epoxy them.

its good to epoxy them after you let them settle into the new tank conditions its a real bummer when you got a dead frag epoxed to your live rock
