For underwater mounting, the "sandwich" idea that John mentions works great.

What I do is simple. Use superglue gel to glue the epoxy onto the frag on one end, and glue the epoxy to the rock on the other end.

Works every time... :biggrin:

Hmmm, seems a little strange to glue glue.

But I will give it a shot. My urchin keeps ripping up my frags anyways, so I have lots to glue down!

Hehe...using glue to glue glue to a coral so u can glue it to a rock.

The idea is simple, epoxy can be shaped and molds well to hold frags upright, but doesn't stick. The superglue makes it stick.
