Epoxy coated aquarium gravel. Midnight Black colour.
The perfect size and shape for anchoring the roots of aquarium plants or to hold other decorations in place. This gravel is coated in epoxy so it won’t have any effect on the chemistry of your tank. That makes it a little easier to make sure everything stays balanced and the epoxy also serves as the perfect place for beneficial bacteria colonies to grow, a necessary addition to keep any fish tank healthy.
