Aquarium Glue

Aquarium glue is a pretty touchy subject in the aquarium hobby. Simply put, people don’t trust the chemicals the glue can release into the water after extended periods of time. In my opinion, they are rightfully concerned as many of us spend countless hours and more money than we’d like to on our aquariums. That being said, here are some specific things to look for when trying to find a safe aquarium glue.

Here are the glues that I use on my own aquariums. I have used all of these and have had no problems with any of them.
