Two Little Fishies - AquaStik Epoxy Putty 4 oz
Two Little Fishies
The AquaStik is a two part epoxy putty that is safe for use in marine and freshwater tanks. It cures underwater and can be used to securely bond rock, wood, and live corals.
Rivers to Reef says: This stuff works well, but it doesn't work instantly. It takes about 5 minutes before this stuff stiffens up, and about 20 minutes to harden, but it won't be at full strength for around 24 hours. What we usually recommend is that you use a reef glue in between the epoxy and the rock and the epoxy and your frag. The frag glue will cure in about 20 seconds holding things together until the epoxy has a chance to cure completely. Epoxy holds much stronger than reef glue once cured.
