Bioscape Coral Sand 5kg – 1 mm Natural Marine Substrate

Bioscape Coral Sand 5kg – 1 mm Natural Marine Substrate

The Bioscape Coral Sand 5 kg (1 mm) is a premium-grade natural marine substrate designed to buffer pH, stabilise water chemistry, and support healthy coral and marine life. Its fine 1 mm grain size provides a natural appearance while helping to maintain consistent alkalinity and calcium levels essential for reef stability.

Composed of crushed natural coral and aragonite, this sand slowly releases calcium and carbonate into the water, keeping parameters steady and encouraging coral skeleton growth. It also aids in the biological filtration process by hosting beneficial bacteria, improving water clarity and overall tank health.

Suitable for marine, reef, and African cichlid aquariums, Bioscape Coral Sand promotes natural behaviours such as burrowing and sifting. Its light colour and uniform texture create a bright, clean look that enhances fish and coral colours.
