Aquascaping is more than just arranging plants and rocks in an aquarium. It’s an art form that allows you to create captivating underwater scenes, mimicking natural habitats. Whether you’re a seasoned aquascaper or a beginner, understanding how to securely attach wood and rock is essential for both aesthetics and stability. In this blog post, we’ll explore various methods to glue wood and rock in your aquascape.

1. Super Glue (Cyanoacrylate Gel)

Super glue, specifically the gel-based cyanoacrylate variety, is a go-to adhesive for aquascapers. Here’s how to use it:

  • Application:
    1. Apply a small amount of cyanoacrylate gel to the surfaces you want to join.
    2. Press the wood or rock pieces together and hold them in place for a minute or two.
    3. For faster bonding, use an accelerator spray.
  • Pros:
    • Quick and easy to use.
    • Creates a strong bond.
    • Safe for aquariums.
  • Cons:
    • Not ideal for large or heavy rocks.
