Why does BRS recommend this?

Jurassic Gel is great for aquascaping with live rock in a dry tank.  The large 200 gram tube allows you to liberally use the super glue to make an ultra-stable aquascape.  The glue is just thick enough to bridge small gaps and gives a much more natural look than epoxy putties. 


High strength clear adhesive for your saltwater aquarium from Paleo Bond. Use Jurassic Gel as a structural adhesive for your aquarium live rock and for attaching coral frags. Full cure in several hours.

  • 20g tube has built in applicator
  • 200g tube comes with 2 applicators

Is this glue composed of cyanoacrylate?
Question by: Jobin Nash on Jun 8, 2017, 10:26 PM
This is a thick, cyanoacrylate-based gel glue.

Have a great day!

I used this to glue a bracket to a brute trash can. Is there anything that will remove the glue if I need to move the bracket?
Question by: Doug Brewer on Dec 22, 2016, 10:15 AM
Great question! The best and most reef safe way to remove the glue would be by cutting it off of the bracket and container. For applications like this, I rely on my trusty bone cutters. :-)

Does this cure underwater? Or do I have to take out my live rock from the tank?
Question by: Amber Hammerel on Jul 20, 2016, 6:08 PM
Hi Amber,
Super Glue will cure very rapidly underwater. We do not recommend putting the tube underwater since it will clog the tip very quickly. If you can either, do a large water change to expose the rocks, then glue them into place, and filling the tank back up will help cure the glue faster too. We actually like using epoxy when we need to work with an adhesive underwater that we cannot remove from the water since it doesn’t react to saltwater like super glue does.

can u use this product in a tank with wet live rock without cycling or curing again
Question by: steven pruessner on Mar 25, 2016, 11:57 AM
Great question!
This can be used in an established tank with live rock to hold it together even while wet. Feel free to let us know if you have any further questions!
Answer by: Connor on Mar 28, 2016, 10:51 AM
Can Jurassic Gel be used on rock after it has been cycled? I purchased dry live rock and need to cycle it before gluing in place.
Question by: Derek Crawford on Mar 14, 2016, 8:34 PM
This will cure to wet and dry rock no problem! Feel free to let us know if you have any further questions!
