The ideal substrate for marine, reef or African Cichlids. Ideal for deep beds, plenum systems, reef or fish tank bottom cover.

• Removes nitrate, nitrite, ammonia and other wastes.
• Unsurpassed buffering capability: keep more fish and invertebrates healthier, longer.
• Maximum surface area -- up to 10,000 square inches of surface area per cubic inch.
• High uniformity coefficient prevents biofouling.
• Supports the proper pH of seawater (8.2) with the fastest reaction time.
• Precision grading and enhanced internal surface area allows CaribSea Aragonite to deliver more calcium, carbonate buffer and essential trace elements than any other substrate.
• Creates a natural biological balance to discourage nuisance algae growth.
• Available in the ideal grain sizes (approximately 1-2 mm) for reef tanks, fish aquarium, plenum systems and refugiums.
• Pure aragonite -- no tar, harmful organics or impurities.
• Never needs replacement -- works with the natural bacteria to enhance performace over the full life of the system.
• Ready to use, minimal rinsing required.

Elements provided by Aragonite: calcium (Ca) 381,000 ppm; carbonate buffer (CO3) 590,000 ppm; strontium (Sr) 7,390 ppm; magnesium (Mg) 1,050 ppm; molybdenum (Mo) 56 ppm; potassium (K) 56 ppm; as well as barium (Ba), lithium (Li), zinc (Zn), manganese (Mn), beryllium (Be), iron (Fe), cobalt (Co), sulfur (S), aluminum (Al), selenium (Se), bromine (Br) and boron (B).
