Rebecca Carr –
Used CoralCrete™ to attach a large branching coral to my rockwork. It set quickly and held firmly. The purple color blends well with the reef rock. No issues with fish or invertebrates after use. Works well in both marine and freshwater setups.
Matt Underwood –
Good adhesive for attaching plating coral to rock. Cured within 24 hours as expected. The working time of 5 minutes is sufficient for precise placement. Slightly messy when mixing, but overall effective.

Fused two pieces of rockwork together for better stability. The putty holds well and matches the rock color perfectly. No signs of leaching or harm to my fish. Recommended for reef aquariums.
