Pisces Natural Coral Rubble 10-30mm Size Sack of 20kg Pisces Natural Products is proud to offer the best coral sand on the market. Unlike other so called “coral sands” on the market which are usually no more than crushed Limestone or other mineral calcium chips, our substrate is pure Calcium Carbonate Coral. It has a bright white colour that reflects the light under corals, promoting their growth. Coral sand is 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 helping the biological filtration of the aquarium.
