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.
Grain size: 0.2-0.5mm
Calcium Carbonate 99.8%
Perfect for Marine and African Cichlid Aquariums, Hermit Crabs and more.
