Glue

[whotzler]

Does anyone know of a good glue that can be applied underwater? I have a couple pieces of larger rock that I would like to glue together without removing them from the tank. Is it possible?

SuperGlue Gel (cyanoacrylate) and Marine Epoxy. For the rock I'd suggest the epoxy. It won't stick perfectly but it's enough to hold rocks together.

Beware the epoxy may cause your skimmer to go crazy for a few days.
