Super Glue Gel + Aquarium Epoxy

For rock, my go to is two-part epoxy. Depending on what you're going for, you can support it with pvc pipe until it fully cures.

It is just a thick CA glue, and overpriced because it is labeled for hobbyists. You can get a much better value for CA glue on Amazon.

Can you use super glue gel by itself underwater?

Yes, just buy cheap super glue gel from a discount store. It's perfectly fine for use in tank.

I would look for thick CA glue. You get a larger quanity for less money per ounce. Something like this:

What does CA stand for?

Cyanoacrylate

If you are stuck on using CA for rock under water, you will need a lot and it will be messy. For this application, like I said earlier, I reccomend 2-part epoxy.

It dries fast, but the thick stuff gives some wiggle room.

This is my all time favorite glue. Amazon has pretty good deals on it.
I second the epoxy suggestion for underwater use though. If you really wanted to, you could make a “sandwich” where you add glue to the “ends” of the epoxy outside the tank before you wedge it in. Could be messy but it might help.

I found Cyanoacrylate gel to brittle to bond rocks, even if you sandwich it with reef epoxy. Never tried 2 part epoxy, it might be good solution.
