CaribSea Arag Alive Crush Coral 2-20lb Bags-Case

Only CaribSea's Arag-Alive! Live Sands contains not just the broad spectrum of natural marine bacteria found in the ocean, but additional specially selected strains of marine bacteria as well. Arag-Alive! compresses new tank cycle time and suppresses the initial ammonia spike. Arag-Alive! creates a natural biological balance, and makes cycling a new aquarium faster and safer. Live rocks and most invertebrates can be added immediately. Gradually introduce fish within the first 3 weeks, and do not exceed one inch of fish per 5 gallons during this time. Florida Crushed Coral - Grain Size 2.0 - 5.5 mm. Use in an undergravel filtered system or as an ad-mixture to finer textured sands, shells and shell fragments produce varied natural colors and void spaces for small macro fauna such as copepods.
