Cavernous water-worn limestone. A firm favourite for all aquarium types being size for size, a lighter weight compared to other natural stone-based decor.
Mix with barnacle clusters to build the foundations of a feature coral reef wall.
The Mountain Limestone offered by Specialist Substrates is formed naturally from the mineral Calcium Carbonate (CaCO3), and will in a small part aid buffering in the aquarium.
Suitable for all aquarium types.
Responsible Sourcing:Our water worn mountain limestone is responsibly sourced without damaging any marine or karst limestone environments.
