Thomas Newman –
I used the hardscape glue to attach driftwood to my tank’s background. It bonded perfectly and didn’t run. The nozzle is precise and easy to control. Great for building structure without damaging the rocks.
Matt Underwood –
The plant glue worked beautifully with my java fern. It stayed in place even after a week of water changes. No dripping or slippage. I’m happy with the results and would recommend it to others.
Carolyn Chapman –
The gel glue is very convenient for attaching moss. It doesn’t spread when applied to wet surfaces. The only downside is the small size—20g is enough for a small tank but not for larger setups.
