Vertex V-Colla Viola Epoxy

By Leonard Ho - Posted Nov 06, 2012 07:00 AM
There are several underwater curable epoxies marketed to aquarists, but Vertex claims they are the first to design a two-part adhesive specifically intended for aquariums: their new V-Colla Viola.

Vertex Aquaristic (Germany) worked with GlueTec GmbH to develop a two-part epoxy stick with the following aquarium-friendly characteristics:

  • Reduced clouding in the water column
  • Extended malleability period to allow aquarists longer working times to attach corals or rocks.
  • Reduced impact on skimming performance
  • pH netural
  • Violet coloration to blend with coralline algae


4 ounce (114g) V-Collar Viola sticks are now available in Europe and should soon be available through authorized Vertex distributors worldwide.

I'm a passionate aquarist of over 30 years, a coral reef lover, and the blog editor for Advanced Aquarist. While aquarium gadgets interest me, it's really livestock (especially fish), artistry of aquariums, and "method behind the madness" processes that captivate my attention.
