CaribSea Arag-Alive Saltwater Gravel - Indo-Pacific Black is best used in deep sand bed type systems and is safe for sifting animals as well as soft belly animals such as stingrays.
The black material in Indo Pacific Black is a geologically young, inert, volcanic material that is similar to the dark, volcanic material that is found throughout the south pacific.
Directions: General Use: 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 CaribSea’s 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.
Berlin Systems: The most suitable substrates are AragAlive! Fiji Pink (#00792), AragAlive! West Caribbean Reef (#0794), AragAlive! Bahamas Oolite (#00793), or AragAlive! Indo-Pacific Black (#00791). Use 1 pound per gallon. Place live rock on top covering the least amount of sand as possible. Use small reef friendly hermit crabs, shrimp, serpent stars, sea cucumbers, and other benthic animals to avoid detritus accumulations.
Sumps, Refugiums, and Deep Nitrate Reduction Beds (DRN): For offline systems, such as sumps and binary systems, the deepest bed possible is suggested for the non-display unite. Use AragAlive! Florida Crushed Coral (#00795) or AragAlive! Special Grade Reef Sand (#00790) and/or corresponding CaribSea Dry Aragonite. Plant macro-algaes such as Caluerpa sp. and illuminate on a counter daylight cycle to the display tank, or for 24 hours. When illuminated,
