Cyanoacrylate glue for aquarium
Super glue gel used to glue corals, mosses and plants to rocks and wood. Safe for aquariums, polymerizes on contact with water.
Detailed explanation
Cyanoacrylate gel glue (super glue gel) is the universal tool of the aquarist. It works underwater and hardens in seconds when in contact with water.
Common uses: Glue coral fragments to plugs, attach mosses and plants to rocks, secure hardscape pieces together, repair small cracks in decorations.
The GEL version is essential (not the liquid one). The gel stays where you put it. The liquid drips everywhere. Aquarium brands (BRS, Two Little Fishies) or any hardware store super glue gel.
It is safe at 100% for fish, invertebrates and corals. Polymerized cyanoacrylate is inert. The white cloud that forms during hardening is normal and disappears.
