This is the best coral substrate you can buy in the world. Unlike other so called “coral substrates” on the market which are usually no more than Limestone or other mineral calcium chips, Pisces coral rubble is pure Calcium Carbonate Coral.

It has a bright white colour that reflects the light under corals promoting their growth. An important component of any marine and African Rift Valley tank.

It’s natural smooth edges enable bottom dwelling fish to clean and feed without injury. It’s porous texture (unlike mined mineral calcium substrate which is smooth) has an enormous surface for growing bacteria—an ideal platform for animals helping the biological filtration of the aquarium.

No living or underwater reef has been touched in the mining of the coral rubble.
