Reef Glue Gel is extremely thick so it may be necessary to invert the bottle upside down and tap it to move the gel adhesive to the applicator tip.
Reef Glue™ is a superior cyanoacrylate gel for gluing and mounting coral frags and colonies to reef rock or plugs. It bonds within seconds and has excellent control, hold and durability characteristics. It can even be used underwater. Reef Glue™ can be used for any aquascaping in freshwater or saltwater aquariums or for any plastics repairs. Reef Glue™ comes in an aluminum tube for extended stability beyond products contained in plastic bottles - it won't dry up in the tube.
With a new formula that is 17x thicker, there’s more control while gluing and less mess in application.
