Seachem Reef Glue
Safe and fast-acting cyanoacrylate gel specially designed to glue and mount coral frags and colonies to live reef rock or ceramic plugs. As coral frags are extremely delicate, it is essential to affix them safely and gently without damage or constant falling off.
This new and improved formula is 17 times thicker than competing brands, making it easier to control with significantly less mess. The glue bonds within seconds, even underwater. It is suitable for both freshwater and saltwater environments. Comes with a no-mess cap in an aluminum container.

Used this glue to mount a small coral fragment on a ceramic plug. It set quickly even under water and the coral stayed firmly in place without any damage. Much cleaner than other brands with less mess during application.
Anna Graham –
The thick consistency makes it easy to control. I applied it to several frags and they all stayed secure. No dripping or excess residue. Works well in both saltwater and freshwater setups.

Great for attaching coral to rock. Set fast and held well. A bit more expensive than alternatives, but the ease of use and reliability justify the price.
