I find that super glue GEL PLUS marine epoxy works best
Mix up your epoxy >>>
Put super glue on rock (dried off spot)
Put Epoxy on super glue
put Frag on super glue
Push for about 10-20 secs (I use Push lightly)
Voila!
Super glue is fine for loose polyps. You need to do it out of the water for best results. Pull the rock, dry the spot, put the super glue on it, dry off the polyp part to be attached and stick it. Put it in the water and the glue dries almost immediately.
Oh, I almost forgot. Pick at your fingers for the next day to get the super glue off.
FUN TIMES! :lol:
