Quick Overview

Why does BRS recommend this?


One of the fastest setting epoxies we have ever used, and is great for mounting large corals, or aquascaping.  The Tunze Coral Gum is really nice as it doesn’t have the traditional epoxy smell like most other on the market.


Coral Gum instant is a two-component coral adhesive for safe cementing of coral fragments to rock, frag plugs or frag disks. No deleterious matter or adhesive residue is introduced into the aquarium water.



  • No odor and does not stick to your fingers

  • Remains semi-flexible and withstands high loads

  • Easy to mix, sets quickly and is unbreakable

  • Cures to a purple coralline color

  • Fresh-water and marine aquariums

  • Aquascaping By Uk on 11/1/2017

    Horrible for trying to aquascape does not hold very well at all. For frags yet to be seen.
  • Best Epoxy Ever! By Brian on 10/2/2017

    I've used several different types of epoxy in the past and this is by far the best I've ever used. Others make a skimmer go nuts, stink to high heaven, or simply are hard to mix properly. This stuff is just awesome. It's super soft right out of the package and mixes in seconds. I've used it to epoxy several Pukani rocks together to make larger structures and it's like a rock. The rocks I put together don't budge at all. I can't understand why other can't get this stuff to work, but it's friggin' awesome.

    Only bad I could say about it is it cures SUPER quick, so use it is very small portions... but once you know that.. it's all good. The only other thing is cost. But based on how well it works and not messing with a skimmer and no stink... this will be the only epoxy I use going forward.
  • Horrible By Jesse on 6/8/2017

    I purchased this and made 5 attempts to attach one bird nest frag to my live rock and failed miserably every time. Will not attach to rock or frag. Total waste of money.
  • Really well made and optimized putty By Justin on 12/28/2016

    I was a bit leary with the price, ordered my first small tube and loved it. Albeit it the price is high, it works great, turns hard rapidly and doesn't crumble like jb weld does half the time. I likes it so much I just ordered the big tub to do some rock repair.
  • Great product By Jason P. on 12/10/2016

    Easy to use. I use it for attaching frag rubble to my main rocks. I like to use it only for smaller jobs. Definitely will purchase again.
  • Super putty but not really "adhesive" By George on 8/13/2016

    This two part putty is easy to mix, doesn't leave a purple residue on your hands (dry your hands before use), doesn't "cloud" the water and cures quickly to a slightly rubbery consistency. It isn't sticky at all, so it won't work well as an adhesive (as some of the poor reviews have indicated). I use it to create a platform in irregular rock surfaces to allow placement of a frag....then glue the frag to the platform with CA.....this composite technique works super well! I've used this to place larger colonies and small frags and both work well.

    The color is purple but slightly lighter than "corraline purple" so it is best to minimize the visibility of the platform....still looks better than a big wad of CA to me.
  • Works well but is expensive By Clint on 5/16/2016

    I really like this stuff but man is it expensive. I went through the 120 gram container mounting 4 frag plugs to my live rock.
  • Easy to mix, but ineffective By KC on 1/19/2016

    Well, I had great hopes for this product... and it does well if you don't put any pressure on the bond. Very neat and clean tho'. I have to recommend E-Marco-400 which easily reconnected my Real Reef Branch Rock which arrived shattered in many pieces. (BRS shipping department sent the rock with a 20 lb. bag of sand-UGH!!) Yes, E-Marco is a little messier, but forms a strong, solid bond in 20 mins. I tried reattaching the many pieces with both products. While the Coral Gum has a near instant bond, that bond does not hold - so no rock to rock use. It might work better if you were trying to cement a frag down into a hole... but not flat to flat surface grip.
  • Great Product By Nate on 11/26/2015

    I have just tried this out for the first time today and was really impressed with it. The gum is super soft and easy to mix and work with and doesn't leave a mess on your hands or in the water. The coral stuck at least as well as any other epoxy that I have used. Another thing that I really appreciated is that it didn't seem to negatively affect my skimmer like other epoxies.
  • Awful By Vaesive on 10/23/2015

    Tried Coral-to-frag, frag-to-rock and rock-to-rock bonding the epoxy doesn't stick. If you somehow do get it to stick, it easily pops off with very little force. Do not recommend.
  • No mess, works great! By James on 8/15/2015

    This stuff is awesome! Mixes with wet hands, no mess, not really any smell, and definitely holds. Just make sure you mix it really well with your fingers, and like some people have said it is epoxy not glue. You do have to press it into something (the rock) really well so it can harden and stay. If not it will not do what you want it too.
  • No Mess By JEMM55 on 7/14/2015

Product Questions

Do the mating surfaces need to be dry and clean? Can the Gum be used to affix a wet frag to a submerged rock?
Question by: Paul Himmelman on Mar 28, 2016 7:12:00 PM
Great question!
This can easily be mounted to wet surface. By pressing the epoxy into the rock it will harden onto the imperfections on the rock. Feel free to let us know if you have any further questions!
Answer by: Connor (Admin) on Mar 29, 2016 3:02:00 PM
Can I use this product to connect live rock together under water? Sort of a second measure to prevent rocks from falling over.
Question by: Spencer on May 20, 2016 4:43:00 PM
Yes, this product will work great for that application.
Answer by: Carter (Admin) on May 24, 2016 12:06:00 PM
You have both 104.75 and 104.76 pictured but I can't pick the product I want when placing the order. Which is which? I want to order 104.76.
Question by: Robert on Apr 11, 2014 11:21:00 AM
Hi Robert,
The only difference between those two models is the size of the container. The 104.76 is the larger 400g container.
