Abigail Bell –
Used it to secure a rock structure in my marine tank. It set quickly and held firmly. No fish or plants were affected. Easy to work with and the curing time is reliable.
Sam Sutherland –
Good for attaching small plants to the substrate. It bonds well and doesn’t leach chemicals. A bit harder to work with than expected, but still effective.
Jonathan Dickens –
Perfect for fixing coral pieces without damaging the base. Cured in 24 hours as promised. No issues with fish or plants after use.
Matt Wallace –
Works as expected, but the stick is a bit stiff to knead. Took a few tries to get the right consistency. Still holds well once set.
