Product Questions

How was it for bonding rock-to-rock or frag-to-rock? I'm still looking for a good solution for use in aquascaping and frag placement. A couple of the other brands I've tried are fine for coral-to-frag.
Question by: David on Apr 21, 2014 6:34:00 PM
Hey David,
The epoxy works great for putting frags on plugs and rock. As for rock to rock applications, its pretty typical to other epoxies. Epoxy is generally my "bonder" of choice for rocks but its a bit different technique. Because its not sticky like glue is, what you do is work it into the cracks and crevices so that when it hardens it keeps the rocks together. Most glue isn't thick enough to maintain a hold on both, though the paleobond does better then most and comes in large enough quantities to make it effective.

Full Details

Vertex V-Colla Voila epoxy is specifically developed for us in aquariums to reduce clouding effect. V-Coll is pH neutral and reef-safe.


V-Colla Epoxy

  • Can be applied in or out of water. For best results, manufacturer recommends application out of water.
  • Can be applied to bonding object immediately but it is easier to work with after 30-60 seconds.
  • Prepared epoxy will be fully hardened in 10 minutes
  • V-Colla can have an effect on protein skimmer's performance due to change in water chemistry. This is temporary. Use carbon media to reduce this effect.

  • good By Christian on 4/4/2016

    works pretty good. doesnt stick to your hands as bad, not as dark of purple as the picture but better than the white or grey epoxies.
  • Works Great By Ryan on 4/4/2016

    I like this epoxy. I've tried several different brands and it's my favorite. It doesn't stick to your hands as much as the others. It does cure very quickly so you have to be ready to place it immediately. If you don't mix the two elements together thoroughly some of the material will dissipate into the water. Even if you mix thoroughly you will get a little dissipation, so I try not to use more than half a tube at a time and of course run carbon and the skimmer afterwards. I have not attributed any coral death to use of this product. I personally don't rely on this product or any other aquarium epoxies to act as my only binder. I use the epoxy to fill-in or build-up material to create a snug fit, then I use BSI coral glue on both sides to ensure permanent attachment.
  • Don't waste your money By ducannn on 12/21/2015

    Rolled the putty according to directions .... putty started setting really fast, as soon as I tried to stick frag plug to rocks it wasn't even sticky enough to hold. Tried again and worked faster to setup still with no luck. Like I said.. don't waste your time or money.
  • Don't use this By catlen on 12/3/2015

    I buy a lot of stuff from you this was the worst products I've ever used it clouded my tank over filled my skimmer I would never use this product again
  • Does not work as advertised By ScottL on 10/26/2015

    I bought this thinking it would stick my frags to the rocks and would not have negative effects. It clouded my water to death, all my new sps frags died, and my skimmer doesnt work. The putty never seemed to dry, and most of the frag pucks came loose. Not sure if I got a bad batch but it basically nuked my tank and didn't stick anything to anything.
  • Good Putty By Ryan B on 8/13/2015

    I purchased this product to add some small ledges to my rock work. Worked great, dried fast, and did not cause my skimmer to go crazy.

    The only downside was that it did have some small hard (rock hard) fragments on the edges when I first opened it. I had to cut these sections off and it was waisted
  • verry good By babnika on 4/16/2015

    Works well no problems here. Third time I've bout this product. Only mix what you can use in a short time cures fast
  • It does what it says and works great By Ozzie on 4/2/2015

    Nothing much to say here, except this is a good product, I would buy again, this was my first time buying.
  • Better Options By Matt on 2/26/2015

    For the price you are better of with the tunze gum, performance is about the same as the TLF putty, but that stuff is way cheaper.
  • Horrible Putty By Xmetal on 8/19/2014

    I have a number of Vertex products that I absolutely love and decided to give this a try. It sounded like a great putty from reviews and videos. The only thing the putty did as described was not cause my skimmer to go crazy. The putty didn't hold even when used with superglue. Does not stick to rock or coral underwater. Every coral (lps and sps) that I used this putty for died shorty after using the putty. All these pieces were in great shape and growing well. I am highly disappointed with this putty and would not recommend it to anyone.
  • Great reef safe epoxy! Doesn't cause my skimmer to go crazy By Christopher Kirkland on 6/25/2014

    Really good product, doesn't drive my skimmer crazy. I do wish it was a little darker purple comes out light pink or gray. Holds well and is easy to use underwater.
  • Average performance By Martin on 6/23/2014

    While I really like how this does not stick to your hands, the smell was very strong and it also caused the skimmer to be supercharged for a couple hours.
