CaribSea Aragonite Seaflor Special Grade Reef Sand 18.1kg

CaribSea Seaflor Special Grade Reef Sand is a premium aragonite substrate ideal for reef aquariums. Free from impurities such as ash, heavy metals, and pesticides, it provides a clean and safe environment for your marine life.

With a consistent 1.0–2.0 mm grain size, this substrate boosts your aquarium’s buffering capacity by aiding the natural dissolution of essential minerals like calcium and carbonates. It’s perfect for use in nitrate-reducing systems such as Plenum or Berlin setups.

Blended with small shells, it also creates a natural habitat for burrowing invertebrates and jawfish, making it both a functional and visually stunning choice for your saltwater aquarium.
