Seachem Reef Glue is an ultra-thick cyanoacrylate gel designed specifically for the demanding environment of a reef aquarium. It provides an instant, high-strength bond for mounting coral fragments (frags), colony colonies, and even rockwork. Because it is a true gel, it stays exactly where you place it—even underwater—making it the professional choice for aquascaping and coral propagation.
Reef Glue is engineered to simplify the difficult task of securing living organisms to wet surfaces.
Ultra-Thick Gel Consistency: The high-viscosity formula prevents the glue from "running" or dripping, allowing for precise application on small frag plugs or vertical rock faces.
Sets Underwater: Unlike standard household glues, Reef Glue is designed to cure quickly even when fully submerged, allowing you to glue corals directly into your display tank.
Superior Strength: Creates a permanent, structural bond that can support the weight of heavy stony coral colonies (LPS and SPS).
Reef Safe & Non-Toxic: Completely inert once cured; it will not leach harmful chemicals into the water or irritate sensitive coral tissues.
Durable Aluminum Tube: Packaged in a specialized tube that prevents the glue from drying out between uses, ensuring a much longer shelf life than plastic applicators.
How long does it take for Reef Glue to dry? It bonds almost instantly upon contact with water. For best results, hold the coral in place for 15–30 seconds to ensure a secure initial set.
Can I use this for "hardscape" (rock) bonding? Yes! Reef Glue is excellent for securing small to medium-sized rocks together to create gravity-defying arches or stable foundations for your reef.
Is it safe to use on soft corals? Yes, but for soft corals that produce a lot of slime (like Leathers or Mushrooms), it is often helpful to pat the base dry with a paper towel before applying the glue to ensure a better grip.
Seachem Reef Dip: Use to disinfect your coral frags after cutting and before gluing them to plugs to prevent infection.
Seachem Reef Plus: Provides the amino acids and vitamins needed to help corals recover quickly from the stress of being fragmented.
Frag Plugs & Disks: The ideal mounting surface for use with Reef Glue when creating new coral colonies.
