Connor Mitchell –
Used Reef Glue to attach a small coral fragment to a rock. It set quickly and stayed in place without dripping. Much easier to use than older glue products. No mess, and the cap stays sealed well.
Blake Newman –
Perfect for mounting corals in my saltwater tank. Set in seconds and held firmly even after a week of tank cycling. The thicker consistency gives better control when applying.
Bella Ince –
Works well for small frags. A bit more expensive than other glues, but the control and clean application make it worth it for reef setups.
Julian Pullman –
I used it to attach a large colony to a plug. It didn’t run or spread, and the bond held strong after several weeks. Great for aquascaping.
