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.
