Coral Sand Adding crushed coral sand to a freshwater aquarium or pond can provide a range of benefits, including increased hardness and pH, a natural source of calcium, pH stabilization, a substrate for beneficial bacteria, and enhanced aesthetics. Composed of pure crushed coral and aragonite, this sand gradually releases calcium and carbonates to buffer pH and stabilise alkalinity, supporting strong coral skeleton formation and balanced water parameters. It also provides an excellent medium for beneficial bacteria, improving biological filtration and maintaining crystal-clear water. Suitable for saltwater, reef, and African cichlid tanks, Bioscape Coral Sand creates a natural environment that encourages burrowing and sifting behaviour while preventing compaction. Its neutral tone complements live rock, coral, and aquarium décor for a realistic marine appearance. Coral Sand Size is 1mm Grade Available in 500G 1KG 5KG 10KG
