Only CaribSea’s Arag-Alive!™ Live Sands contains not just the broad spectrum of 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 20 litres during this time.
