Description
TMC EcoSand Coarse – Natural and Sustainable Marine Aquarium Substrate
TMC EcoSand Coarse is a premium, eco-friendly substrate specially designed for marine and reef aquariums. Made from carefully selected sea-washed British sea shells, this natural aragonite sand provides a coarser grain size, replicating the texture of ocean sand while offering excellent water flow and aeration in the substrate layer.
Its coarse texture is ideal for larger invertebrates, burrowing species, and aquascaping, while supporting the growth of beneficial bacteria that promote biological filtration. EcoSand Coarse also helps maintain stable pH and alkalinity, creating a natural and healthy environment for all marine life.
