Seachem Reef Glue 20g
Mount coral frags in seconds — even underwater. Seachem Reef Glue is a premium cyanoacrylate gel for fixing coral frags and colonies to reef rock and frag plugs. It grabs within seconds, holds hard, and can be applied with the frag still submerged — no need to pull corals out of the water.

- 20 g (0.7 oz) tube
