Nyos Reef Cement 500ml

NYOS® REEF CEMENT – Fast-Setting Reef-Safe Coral & Rock Adhesive

NYOS® REEF CEMENT is a fast-curing, reef-safe adhesive designed for securely fixing corals, rock structures, overhangs and aquascapes. The powder mixes easily with cold water and sets completely within just two minutes, allowing quick and stable construction both inside and outside the aquarium.

It is safe for fish and corals, can be used underwater, and provides strong, durable bonds for complex structures such as columns or free-standing coral placements. Once cured, the cement blends naturally into the reef and is quickly overgrown by coralline algae.
