This is the best coral sand you can buy in the world.
Unlike other so called “coral sands” on the market which are usually no more than crushed Limestone or other mineral calcium chips, Pisces substrate is pure Calcium Carbonate Coral NOT crushed rock.
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 sand.
Calcium Carbonate 99.8%
Perfect for Marine and African Cichlid Aquariums.
