Absolutely stunning collection of pink and white barnacle clusters for project assignments or "pick 'n mix" retail sale. A firm favourite for all aquarium types being size for size, light weight compared to other stone-based decor.
Mix with our water worn mountain rock to build the foundations of a feature coral reef wall.
Barnacle shells offered by Specialist Substrates are 100% natural. Sea shells are 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: Barnacle clusters are collected throughout Asia Pacific regions as part of routine maintenance of harbour entrances and water outfall pipes.
