Seachem CoralCrete

Seachem CoralCrete is a two-part epoxy putty designed to anchor coral securely to rockwork or bond rock structures for enhanced reef stability. With a 5-minute working window, it provides ample time for precise placement before setting. The putty fully cures within 24 hours—whether submerged or in air—and blends seamlessly with synthetic reef rock in purple and gray tones. Ideal for branching corals, large polyp varieties, and plating species, CoralCrete delivers reliable adhesion while remaining safe for all aquarium inhabitants when applied correctly. Available in 57g and 114g sizes.
