Nyos Reef Cement is a reef-safe, rapid-setting aquascaping cement designed for securely bonding corals, live rock, and reef structures in both freshwater and saltwater aquariums. Its fast cure time and strong underwater adhesion make it an ideal solution for creating stable, long-lasting reef builds.

Reef-Safe & Low-Impurity Formula

Formulated to be safe for fish and corals once cured, this cement is designed specifically for aquarium use.

Fast-Setting Underwater Bond

Mixes easily with water and begins hardening in roughly 2 minutes, allowing for quick placement of corals, rocks, and structures both above and below water.

Strong Structural Aquascaping Support

Ideal for attaching overhangs, pillars, and complex reef structures, helping aquarists build stable aquascapes that hold their shape over time.

Easy Mix, Simple Application

Powder form mixes at a 3:1 ratio (cement to water) into a workable paste you can shape and apply directly to rock or frag surfaces.

Natural Reef Integration

Once cured, coralline algae quickly overgrows the cement, helping it blend naturally into established reef environments.
