CaribSea Seaflor Special Grade Reef Sand

A versatile dry aragonite sand for any reef. CaribSea Seaflor Special Grade Reef Sand is a 1 to 2 mm dry aragonite sand for reef and marine aquariums. The consistent grade dissolves minerals like calcium and carbonate to support your reef, and it works beautifully as a display bed or in nitrate-reducing plenum and deep-sand systems. Small shells mixed in make it a favorite for jawfish and burrowing invertebrates. Build your reef with salt mixes and corals.
