Frags and Epoxy

I had been randomly buying gel superglue...

but I find it doesn't hold well for me. The longest I've had it hold a frag is 2 months.

I use epoxy now.

 

I use superglue gel to attach hard corals to frag disks. I then use epoxy to hold the frag disks to the rock. You don't want to use epoxy directly on the frag because it heats up as it cures and can burn the coral.

 

Just to clarify what I said - I only epoxy the frag disc. My frags come preattached to discs... so I didn't mean I literally epoxy the frag.
