Coralline Purple Reef Safe Epoxy Putty

Compared to many other reef epoxies, this one is very pliable and easy to mix, work quickly before it sets. Color is great, Order 2 if you plan on doing a lot of work, I wish I had. Edit: next day, still very happy with this product, again it is super easy to work with without moving rocks around due to how pliable and soft the mixed product is. As stated on the label it DOES indeed harden in 5 minutes, so plan ahead and make sure you know where you want to place your rocks. Highly highly recommended. It WILL stick to your hands, and also the rocks, I recommend wetting your hands with your reef water before yo7 mix it, or wear gloves. After an hour it's very easy to peel off your palm also, so don't overthink it. If you have an established slime coat on your rock and you are doing this 7nser water, use a clean toothbrush to clean the contact points beforehand.

This product was recommended on BRStv on youTube. aka Bulk Reef Supply at one point and so I tried it out. I thought it worked great and love the color, however, I noticed once it’s been in the water for a few weeks if you touch it or scrub it with tooth brush it’s flakes and dust creates a kind of cloudy substance when disturbed. On the plus’s side easy to scrape off if you need to remove it. The worst part about it is the smell when you take it out of the package, it’s pungent but once in the water you don’t smell it. You break off what you need, feels like silly putty, you knead it for about 5 minutes, make sure your hands are dry, once the color is mixed, apply it in your tank where needed. If your hands are wet while kneading it crumbles and is useless really. So I knead it and place it where I need it. My tank has been set up for a year. I had a few aptasia and used the epoxy to cover crevices and holes they were in. No more aptasia.

This stuff is odor central. Expected. It is the two part thumb puddy. It's got the coraline color when you mix it together. It was 90 degrees outside when I used it, and it setup rather quickly. I didn't anticipate using as musch as was needed when I initially ordered, and should have opted for the larger size tube. I bonded three separate rocks together, roughly 2.5lbs a piece. This might not hold long term, but I'll see what happens. I forced as much material I could, into the available openings at the mating surfaces. This isn't too sticky, and I had no issues with my disposable gloves. Thanks to the current administration, I have a feeling the prices of these items will only increase. Good luck.

If your using dry rock, not wet, this stuff works great. Dont forget to knead it to activate it. Hardens superfast so have a plan beforehand for how you want your pieces placed. It is much more tiny than expected. I had to buy several sticks. Basically one stick for each connection. Too expensive. But it works so great and the color makes it look more natural. I used the dry live carib sea rocks

Just wanted to update my review to state that 7 months later and it is still holding strong in my tank. Rockwork still solid and none of the animals (corals, pods, inverts, and fish) have been affected by any chemicals or anything. It stunk to high heaven out of the package and was quite expensive for what little amount of clay you get, but it has done its job as far as I can tell. Original Review: "Can't really say one way or the other right now as it is not yet in a working system. I will update once I see how it actually holds up under water. Addressing those who complained about how non-sticky this is......THIS IS NOT AN ADHESIVE i.e. this is not a glue. This is an epoxy that hardens into place and cures in an hour or so. Think of this more as clay that hardens on its own. You place your rocks on each other how you want them and then pack this stuff along the seams so that when it hardens it is providing a strong support base around where the rocks meet, preventing tipping/collapse. It works best when the rocks are stacked to where they naturally stay in place and you are using this epoxy to just add that extra layer of security against accidental collapse. As noted by others, this stuff stinks pretty bad. You need to knead/mix it up prior to use in order to "activate" it, and it becomes a bit tacky to the touch. I got some of this on my fingers and three days later after multiple scrubs/washes I can still smell residual odors."

First off this stuff does an AMAZING job of sticking to your fingers! Wait ...... you want it to stick to the rock? Well, no. I have used clay type epoxy before and knew what I was getting into but I have never had one stick to my fingers this bad. The worst part is you try to stick it to the rock and it wont grab the rock cause its still stuck to your fingers. But wait, there is more! This stuff wont stick to the rock period. I got about half way through building my design when a rock wouldn't fit so I removed it only to find 3-4 other pieces of rock fall that were supposedly epoxied together. When I picked them up the epoxy on those rocks had hardened so it was no longer usable and it fell right off the rock. So it is true, this stuff will harden in 5 min, but it wont stick to rock. The next morning I checked some of the joints and most of them came right apart. My rock was wet from rinsing but in a dry tank. Nowhere on the label does it say anything about dry/wet so I figured damp rock wouldn't be a problem. I was wrong. Honestly if you do a good job of setting up your rock and making sure it is stable (wiggle them as you set them) you will most likely be fine. This stuff barely helped and for the trouble it caused I will not buy again. Save yourself the trouble and just buy fiberglass rods, a long drill bit, and join the rock with the rods. Plus this method allows you to take it apart ....... though the epoxy didn't hold so I guess the epoxy method also allows you to take it apart later.

This stuff is great for doing rockscapea or just general tank repair/work. It sets up quick but you’ll know when you need to hurry because it gets relatively warm when curing. Iv abused my structures that I built with this stuff and it holds up! Every bit as hard as the rock it’s gluing.

I use this to mount rocks to rocks and frag plugs. The color blends in nicely. I mix the putty and make little balls first. Then I use a drop of reef super glue to get a quick long lasting bond. If you need to move the frag it will pop off with a little effort.
