Glue for reef tank

[Duke4Life]

But this new one I got says that it is not recommended for bonding parts which are subject to great shock or immersion in water. So will this one work?

Your over thinking this

No because I tried a practice one right now and after a while, the rocks broke apart and it didn't glue anymore

Nevermind, I got this new glue instead, it ONLY has cyanoacrylate. Will this one work?

That will work but it's probably going to be a little runny. you need the kind that is a gel it would work better.

What are you gluing? You mention "rocks" above. If you are trying to glue rocks together, I'd suggest using a putty epoxy such as Rectorseal, which can be found at HD or Oatey Fix-it-stick. I'd only use one of the "super glues" to glue a coral to a plug.....never to glue rocks together.....or a coral to rock. It just won't work. Also use this epoxy to glue corals to rock.

In addition, if your gluing rock together, I'd suggest cutting up a plastic clothes hanger and using this rod material between the two rocks. Using a masonry bit, drill a hole in each piece of rock and insert the hanger rod. Use the epoxy to hold the rock together. Works great.

Ok thanks and yea I'll just buy the epoxy stick for the rocks and save this glue to glue the corals to rocks.

Have you thought about drilling the rocks and using PVC to hold them together instead of glue or epoxy?

Wait, you are gluing rocks together? Super glues require flat surfaces being attached.

If you are trying to span large gaps, like rough pieces of rock, you'd be better of with an epoxy putty.

Edit, I see Red Fish already mentioned this.

Yes I don't know any super glue that will hold rocks together unless it's small pieces of rubble you are attaching.
