Used Reef Glue to attach a coral fragment to a rock in my saltwater tank. It set quickly and held firmly even after a week of tank activity. The glue didn’t bubble or weaken. Easy to apply and works well underwater.
Vanessa White –
Great product for fixing small plastic parts in my freshwater setup. The aluminum tube stays fresh and doesn’t dry out. Applied it under water and it bonded perfectly without any mess.
Diana Mackenzie –
Worked well for mounting a small coral colony. Set fast and stayed strong. A bit harder to control than expected at first, but with practice it’s manageable.

I used it to repair a cracked plastic piece in my tank. It stuck securely and looked natural. No visible residue or discoloration after curing.
