Gorilla Glue for Corals.

Question about Gorilla Glue (the original stuff). Have you used it? If not is it because it doesn't work or because it is toxic. I would really like to know.

The regular Gorilla Glue now comes in a clear drying formulation. All I can confirm is that it is a Polyurethane Adhesive.

They also make a Super Glue Gel, which is the same as Super Glue (Ethyl Cyanoacrylate adhesive( but it's the same as Super Glue.

I have used the Gorilla Super Glue with no issues. But I think the Gorilla Glue would be even better (It needs moisture to activate). I would like to try it but not until I have some assurance that it would not be toxic in the tank.

Thanks to anyone who can help.

i dont think theres a problem using the regular glue if youre glueing dry pieces together and adding to water later.

the gel is the one to use, you can glue frags and rocks underwater

Dont forget, safe or not, it expands and is unsightly in the tank. I stick to crazy glue because it is small, powerful, and usually isn't a mess unless I mess it up. I guess if your using it to cement rock work before adding to the tank, its likely ok, but it could still show through.

+1 on the superglue and it cures almost instantly when it gets submerged in water.

I use the gorilla super glue gel. Works great and way cheaper than the other brands. I get it at Home Depot for around $5 for 20 gram tube. Also the cap has a needle in it so no clogging up.
