Aquarium CO2 Glue Fish Safe

Hygger Aquarium Glue is a strong water proof and fish safe adhesive for bonding corals, woods, rocks, and mounting plants. A terrific accessory because you never know when you need to glue something. To something else. Or together. We also recommend a pack of weights to help sink landscaping accessories when necessary.

Great for freshwater and saltwater aquariums.

Each purchase comes with  three  glue tubes (kindly imagine from picture of two).
