Thomas Chapman –
Used this glue to attach a small coral fragment to a rock. It held firmly after a week and the coral stayed in place without any signs of stress. Easy to apply and works well in a saltwater setup.
Jane Newman –
Good product for reef aquariums. The gel sticks well and doesn’t run. I attached two corals and both stayed in place. A little messy to apply, but effective.
Carol Powell –
Perfect for attaching coral pieces without damaging the colony. Set quickly and stayed strong even after several water changes. Highly recommended for reef keepers.
