Polyplab Coral Frag Glue is a fast-setting underwater adhesive formulated for securely attaching coral frags, small rock pieces, and aquascaping elements in marine and reef aquariums. Its strong, reef-safe bonding ensures corals stay firmly fixed even under currents or water flow, reducing the risk of dislodgement or damage. Designed for easy application, the glue bonds quickly and cures underwater, making it ideal for in-tank fragging and layout adjustments without needing to remove livestock or dismantle rockwork. By providing a reliable and durable hold, Polyplab Coral Frag Glue helps reef keepers build stable coral structures, maintain clean aesthetics, and support healthy coral growth over the long term.
