CaribSea Arag-Alive Special Grade Reef Sand

The versatile live sand for almost any reef. CaribSea Arag-Alive Special Grade Reef Sand is a live aragonite sand with a 1 to 2 mm grain that suits most reef and marine aquariums. The medium grain resists being blown around by strong flow yet is still fine enough for sand-sifting livestock. As 100% aragonite, it buffers pH toward natural seawater and releases calcium and trace elements, and it arrives pre-loaded with live marine bacteria for a fast, stable cycle. Pair it with saltwater essentials and live rock.
