  • TERRIBLE By Paul on 12/9/2016

    Ecotech has a vast array of effective products, however this one was a severe letdown. This glue is one of the worst glues/epoxies I have ever worked with. This glue is terrible at adhering to surfaces underwater and If you can actually manage to get it to stick to your rock or a frag plug it typically wont stay stuck for more than a day. Save yourself the money and get some of the BRS extra thick glue it works much better.
  • GARBAGE By Terry on 11/4/2016

    Really surprised this glue was so bad coming from a great company like Ecotech. All the other products I've bought from them, and their customer service, has been awesome. I'm especially pissed I bought the large bottle, and ended up throwing it away.

    Just about everyday I find a piece that has came off the rock in my tanks. So now I'm in the process of replacing multiple frags to rock mounts with different glue.

    I've been in the hobby for years and never had a problem with glue until using this stuff. Just thought I'd warn you guys.
  • Don't let the Ecotech fanboys fool you! By Randy on 4/16/2016

    While Ecotech does certainly make amazing, and innovative products for the reefing community, this is not one of them. The glue somehow manages to give the illusion that your frags are being held to your rock, but in reality, its just gonna be in the sand bed a minute later. Do yourself a favor, look elsewhere!
  • Would not stick to live rock or come out of bottle By Clint on 2/4/2016

    I was let down by the performance of this glue. It took lots of effort to get it to stick to submerged live rock and the bottle is very stiff which does not allow for all of the material to be easily dispensed.
  • Not the glue you want By jsbull on 1/2/2016

    My experience started off poorly when I received this. The cap was leaking and it took pliers to be able to get it unscrewed and unclogged.

    Be ready to chew it off of your fingers because you CANNOT use this stuff without getting it everywhere. Which leads me to say that it seems to stick to everything I don't want it to and be mediocre on everything I'm trying to glue.

    I have used it on corals glued to live rock, which snails have later knocked off. I'm also trying to glue some GSP to my back glass and I've glued 4 frags. Each morning is now a game. Which one fell off over night? Oh, I picked #3, but it was #2. Give me a break. It's a difficult game.

    LIVEWRECK nailed it. When this stuff is in the water, it's a very annoying putty that won't grip anything. It's really something to avoid.
  • overprice By gerliba on 9/8/2015

    it's a good product I like it but I think it was overprice other projects do the same thing as this one also ill dry really fast and dry inside the bottle
  • Overpriced By joe on 7/23/2015

    Way too thick and clogs up fast. The BRS glue is much cheaper and better.
  • good stuff By peter on 6/25/2015

    pretty good glue. wish there was an easier way to break that skin after putting it in salt water and getting it to stick to the rocks. sometimes it seems it won't stick to anything but your fingers. but that is with all coral glue. just wish somebody would come up with something better
  • Doesn't hold anything By Dave on 6/6/2015

    I have tried gluing several frags. In less than 24 hours the frag comes off the plug. I have had better luck with regular super glue from Home Depot.
  • Works great By Denise on 4/9/2015

    My new favorite coral glue, holds well and is easy to use. Not too runny or thick works well for all my frags.
  • Major disappointment By Livewreck on 3/30/2015

    This glue is great for connecting almost anything to anything else when the gluing process is performed in air. So it worked perfectly when gluing coral frags to pieces of rubble. In fact, it was the best glue I ever used for gluing pieces of rock together IN AIR.

    But as soon as the glue hits saltwater, it skims over immediately, then becomes putty-like, and will not stick the rubble to live rock. I kept applying more and more glue just before placing the frags in my tank but they never held. After several attempts, I'd have to remove all the glue and start over. Still no adhesion. - I had 7 frags to attach to my live rock and met with 6 out of 7 failures.

    Finally, I had to go to my LFS and buy a tube of Seachem's Reef Glue, and that worked the first time, every time. - I've had marine aquariums for more than 10 years. I know how to glue frags onto live rock. And I simply do not understand the rave reviews of some of my fellow hobbyists. Cg glue is the worst coral glue I have ever used (and I'm sorry to say that because my other Eco Tech products are first class).
  • Seen better By dwayne on 10/12/2014

    For the price and what it does I was not impress with it. Had to use too much and also it is easy to get hard once use under water. I ended up throwing it away because it was hard.

Product Questions

With the benefits of having "glued rock" in place, as a beginner to the hobby, why would you want to glue to rocks in place together? I have seen things that suggest when introducing new fish, you want to rearrange your rock to help with less aggression to the new fish from the established ones and to help prevent the "protecting my space" that tends to happen with the established fish.

Question by: Brad Ballard on Jan 18, 2016 10:49:00 AM
Great question!
The easy answer for gluing rocks is so they do not get knocked over and break or scratch the tank. This happens more often than not when not secured well or when working in your aquarium. Most rocks do not fit together well to make an aesthetically pleasing pile with out balancing or gluing them. Most fish in the reef tank will tend to not be aggressive as this clashes with many of the most common reef safe fish. Feel free to let us know if you have any further questions!
