Seachem Reef Glue is easy to use and cures quickly. It is thicker than typical 'glu'e and more like a gel, holding frags in place while it cures in or out of water.
Love this glue! Super easy to use. I had been using regular super glue for awhile, and thought I would give this a shot. Glad I did! I will be using this product from now on.
Advantages: Able to manipulate the glue under water. Also doesn't leave a residue on the waters surface ( unlike super glue) and cures quickly.
Advantages: Good nozzle...thick non running gel.
