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.

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.

I bought this to use on my aquascape. I used it create tree like structures with the rock, I did use acrylic rod in the middle but used this to hold things together. I can say that it works. Ultimately, it is epoxy and not glue, so if you want it to stick to rock, make sure you push it into the rock well.
