Similar to other reviews, this glue takes an unexpectedly long time to dry, and unfortunately, it doesn’t hold well at all. I was trying to glue some rocks together to create a cave for my saltwater tank, and after waiting about 8 minutes for it to "set," I gently tried to pick it up and place it in the tank—only to have the pieces completely fall apart. On top of that, the glue tube arrived with a small hole in the center, causing the glue to spill out and get all over my hands. This has definitely been a frustrating experience and not one I’d recommend for anyone trying to use it for aquarium projects.

Doesn’t hold. Needs a ridiculous amount of time to dry and when it finally does it just breaks off. And the next time you go to use it the tube cracks and glue gets everywhere.

I wanted to make a rock cave for my turtle and didn't want it to collapse on her. So I bought this, it was easy to squeeze the glue out. It's VERY IMPORTANT that you let it set. Like most glues you need to let it set for atleast a day. I left mine to set for 48 hours before I put the rocks into the water. Also make sure u apply the glue on dry items.

It’s easy to unstick when moving Coral without damaging Coral
