CaribSea Arag-Alive Saltwater Gravel - Special Grade Reef Sand was originally engineered to be used in Jaubert (plenum) systems. It may also be used in Berlin systems as a static bed. It is “soft belly safe” as well as “sifter safe”.
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.
Plenum Systems: After placing plenum plate in position, add 2 pounds per gallon of AragAlive!™ Special Grade Reef Sand (#00790) or a split layer of AragAlive!™ Florida Crushed Coral (#00795) at 1 pound per gallon for the bottom layer and then a top layer at 1 pound per gallon of AragAlive!™ Special Grade Reef Sand (#00790) for the top layer. In both cases, a screen should be placed either between the upper and lower layer, or about mid level to discourage sea life from burrowing down to the plenum plate and disrupting plenum function.
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
