Sue Metcalfe –
I used RockLock to attach a small coral to my reef tank. It set quickly and held firmly. The process was simple and didn’t damage the coral. Works well both in and out of water.
Ella James –
Great product for building rock structures. Set in about two minutes as advertised. Easy to apply and strong once cured. Slightly messy when mixing, but overall very effective.
Neil Allan –
Used it to secure a piece of rock in my aquarium. It bonded well and didn’t cause any discoloration or harm to the coral. Very reliable for reef building.
