Bonding Aquatic Plants and Hardscapes
Introduction to Aquarium Adhesives and Glues
Creating a visually stunning aquascape design begins with a strong foundation: your aquascape. These foundational elements—stones, driftwood, and other materials—form the structural layout that brings your aquarium setup to life. Hardscape elements are essential not only for aesthetics but also for supporting aquatic plants and providing hiding places for fish and invertebrates.
During setup, fixing hardscape securely ensures long-term stability and safety. A loose rock or floating wood can disrupt the balance of your aquascape. Traditional methods like silicone adhesive are reliable, especially for glass and resin components. However, with drying times of up to 48 hours, silicone isn’t always ideal for quick setups.
More practical methods for gluing decoration include cyanoacrylate-based aquarium glue, which is safe for aquatic life once cured and adheres quickly, even underwater. Products like ProGlue Aqua Plant Glue, Rock Glue and Frag Gel Glue are ideal for making your Aquascaping ideas a reality fast!

Fixing Aquarium Plants
Common Issues with Aquarium Plants
A major challenge is how to fix aquatic plants securely without damaging them or disturbing your layout. Floating plants not only look messy but can block light and reduce CO₂ distribution. Rhizome species like Anubias or Bucephalandra should never be buried in substrate, they need to be tied or glued to surfaces like rocks or driftwood.
Using aquarium glue can solve these issues. Safe, effective adhesives make it easy to anchor plants where you want them and keep your layout intact.
For epiphytes, apply a dot of gel superglue directly onto hardscape elements and press the plant in place. Products like ProGlue Aqua Frag Glue bond in seconds and work on vertical or irregular surfaces.
To hide visible glue, sprinkle sand or soil before curing, or use moss to cover connection points. This not only improves visual appeal but ensures a more natural look.

Enhancing Decorations in Your Aquarium
Choosing the Right Decorations
When selecting aquarium decorations, prioritise safety and compatibility. Use materials like driftwood, lava rock, or aquarium-safe resin ornaments that won’t leach harmful substances into the water. Avoid sharp-edged or painted items unless labelled as aquarium-safe.
Using aquarium glue allows for precise placement and bonding. Whether you’re gluing decoration to rock, wood, or glass, adhesives like ProGlue Aqua Rock Glue or Plant Glue ensure secure and safe attachment. Aquarium Adhesive Activator can be used to speed up cure time, but it is essential to use an aquatic safe activator like ProGlue Aqua Activator, as many standard activators are toxic to aquatic life.

Fixing decorations in place with aquarium-safe glue like the ProGlue Aqua range, helps prevent shifting due to current or fish activity. You can also attach moss or small plants to hardscape features using gel-based adhesives like ProGlue Frag Glue, adding texture and contrast.
By combining the right decorations, adhesives, and layout techniques, you’ll craft an aquarium that looks professional and remains structurally sound over time.
