Superglue alone never really worked for me. Just too difficult to get enough gel on contact points. Even when it held for a while it was too brittle and broke away. Also doesn't work on softies very well. I use a sandwich of glue gel, reef putty, glue gel. I mix the putty and shape accordingly. Put a spot of glue on top then press the coral through the glue into the putty. Shape the putty around the coral base and into the crevices etc. The glue does a good job holding until the putty sets. The putty gives long term holding I find. To place in the tank I put a spot of gel on the underside of the putty attached to the coral and press it into place in the tank. Again shaping the putty into crevices in the rock. Glue holds long enough for putty to cure hard. Works for me.
