IC-GEL is a thick, reef-safe cyanoacrylate adhesive (super glue gel) commonly used in saltwater aquariums for mounting coral frags.

It’s designed to bond quickly underwater or on damp surfaces, making it ideal for attaching corals like SPS, LPS, and soft corals to frag plugs, live rock, or reef structures. The gel consistency is key—it doesn’t run like liquid glue, so it stays exactly where you apply it and gives you better control during aquascaping.

Key features:

Fast curing (seconds to minutes depending on conditions)
Thick gel formula for precise placement
Works underwater or in air
Reef-safe once cured
Strong bond for coral frags and rockwork

Typical uses in reef tanks:

Gluing coral frags to plugs or rocks
Securing loose coral bases
Small aquascape fixes or coral repositioning

Most reefers pair it with a bit of epoxy putty for larger or heavier corals—gel for the initial tack, epoxy for long-term strength.
