Ideal for Freshwater Aquascaping
AquaStik Stone Grey is particularly useful for securing natural hardscape materials in planted aquariums. Its mouldable consistency allows it to fill small gaps between irregular rock surfaces, helping create more stable arrangements.
Common freshwater aquascaping applications include:
- Securing aquarium rocks and stone formations.
- Stabilizing smaller pieces of driftwood and hardscape.
- Attaching Java Fern, Anubias, Bucephalandra, and other suitable aquatic plants to rocks or wood.
- Creating natural-looking rock arrangements for planted aquariums.
- Securing decorations in paludariums and aquatic displays.
- Repairing or reinforcing suitable aquarium decorations.
For larger or heavier hardscape structures, additional mechanical support may be necessary. Epoxy should not be relied upon as the only support for unstable or load-bearing rock formations.
How to Use AquaStik Epoxy Putty
- Prepare the Epoxy: Remove the required amount of putty from its packaging. Keep the remaining unmixed portion properly stored.
- Knead Thoroughly: Mix the putty by hand for approximately 1 minute until the colour becomes uniform.
- Apply Promptly: Press the mixed epoxy firmly onto the surfaces you wish to secure. Apply within approximately 2 minutes of mixing for best results.
- Hold in Position: Press and hold the attached material in place for approximately 2 minutes.
- Allow to Harden: The epoxy begins hardening in approximately 20 minutes.
- Allow Full Curing: Complete curing takes approximately 24 hours. Avoid disturbing the attachment during this period.
Important: Working & Curing Time Once mixed, AquaStik has a working time of approximately 5 minutes. Prepare only the amount needed for immediate use. Although the putty begins hardening after approximately 20 minutes, allow 24 hours for full curing before placing significant stress on the bond.
Suitable for Freshwater & Marine Aquariums
AquaStik is designed for a variety of aquarium applications, including freshwater planted aquariums, marine reef aquariums, ponds, and paludariums.
In marine aquariums, it can be used to secure coral fragments, live rock, and other suitable reef decorations. In freshwater aquariums, it provides a convenient solution for attaching hardscape materials and selected aquatic plants.
The stone-grey finish is especially well suited to natural rockwork, where it can help make attachment points less noticeable.

Aquascaper's Tip For rock-to-rock attachments, press AquaStik into natural crevices and irregular surfaces rather than relying on a thin layer between smooth rocks. This allows the putty to form a stronger mechanical connection as it cures. For delicate aquatic plants, use only a small amount and avoid covering rhizomes or growing points.
Build and secure your aquarium hardscape with AquaStik Epoxy Putty (Stone Grey), available in 2 oz and 4 oz sizes at Aquascaperoom Canada.
