Bioscape Natural Coral Sand 5kg 1mm Marine Aquarium Substrate

Bioscape Coral Sand 5kg (1mm) is a natural marine aquarium substrate designed for reef aquariums and marine fish systems. Made from crushed coral, this fine sand creates a natural looking base while supporting a healthy marine environment.

With a fine grain size of approximately 1mm, this coral sand helps replicate a natural seabed appearance inside marine aquariums. The smaller grain size makes it ideal for reef aquascapes and marine tanks where a clean, natural substrate is desired.

The calcium carbonate composition provides an excellent surface area for beneficial bacteria to colonise, supporting biological filtration within the aquarium. When used with live rock and quality filtration, coral sand helps maintain a balanced marine ecosystem.

Bioscape Coral Sand is supplied in a convenient 5kg bag, making it ideal for smaller aquariums, topping up existing substrate or creating decorative areas within reef tanks.
