Aragonite Reef Sand reduces fish stress by recreating a natural reef environment in the tank. It is precision-graded for efficient calcium carbonate buffering and high in strontium, magnesium, and other essential reef elements, and always silica-free. It is harvested from pristine ocean waters – not collected from beaches or reefs – and contains no harmful tar, organics or impurities.
Its buffering capabilities are unmatched, helping to maintain a proper pH of 8.2 without the constant addition of chemicals to the tank. Each pound of Aragonite provides up to 10,000 square inches of surface area for maximum growth of beneficial, water-purifying bacteria. These bacteria help control nitrate, nitrite, ammonia, and other harmful waste products to keep your fish healthy and your tank clean. CaribSea Aragonite Reef Sand has an ideal grain size for reef tanks, fish tanks, plenum systems, Berlin systems, refugiums, and more.
Directions: Rinse well with clean water. Do not use soap or detergent. 1 to 2 pounds of sand per gallon of water is usually sufficient for most displays. More exact measurements can be obtained from the manufacturers website. For best results, follow all directions on packaging. When using Aragonite for African cichlids or other freshwater applications, a slight cloudiness may persist until the aquarium cycles due to high rates of calcium carbonate dissolution.
