Caribsea Arag-Alive! Fiji Pink Marine Live Reef Sand Substrate 20 lb

For best results, use at least 1 pound of AragAlive! per gallon of seawater. For deep sand beds use 2 pounds per gallon. Do not rinse. AragAlive! may also be used to seed CaribSeas dry aragonite products. AragAlive! compresses new tank cycle time and suppresses initial ammonia spike. Live rocks and most invertebrates may be placed in aquarium immediately. However, gradually introduce fish within the first 3 weeks, and do not exceed one inch of fish per gallons of water during this time.
