Nature's Ocean Live Reef Sand is premium, 100% natural, bio-active aragonite sand for marine aquariums. Made from real ocean sand, packaged in its natural state, it comes ready for instant use: just add saltwater and fish for instant cycling and a thriving tank.

• 100% natural live ocean sand, packaged in its natural state
• Instant cycling for immediate nitrogenous waste removal and organic balance
• Contains natural live marine bacteria to quickly stabilize your tank

This all natural marine sand contains live beneficial bacteria biofilm - the same cultures that naturally maintain healthy balance in the ocean! It activates immediately upon immersion in saltwater, instantly beginning to remove ammonia, nitrite, and nitrate to establish biological balance. Since these bacteria are straight from the ocean, they are more effective than cultured live sand products that artificially replicate marine conditions. This original patented formula is ideal for most applications*.

In addition to beneficial bacteria, this substrate also provides essential trace elements for healthy coral growth, including zinc sulfate, calcium chloride, manganese chloride, cobalt chloride, copper sulfate, sodium molybdenum, strontium chloride, nickel chloride, potassium bromide, and sodium silicate.

Recommended Use: Use a minimum of 1lb Bio-Activ Live Argaonite Live Sand per gallon of saltwater. Set up an appropriate filtering system and allow it to circulate. During the first month introduce no more than 1" of fish per 5 gallon saltwater. Nature's Ocean recommends using Nutri-SeaWater Natural Live Ocean Saltwater to instantly establish an ideal marine environment.

*Note: Not recommended for undergravel filters.

CaribSea Aragonite Special Grade Reef Sand is an ideal, natural substrate for marine, reef, and cichlid aquariums. This pristine ocean sand helps create a natural biological and mineral balance while promoting the overall health of fish and invertebrates.

• Perfect for marine, reef, and cichlid aquariums
• Helps create a natural biological and mineral balance
• Promotes healthy fish and invertebrates

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 manufacturer's 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.

Composition:
Magnesium - 1,050 ppm
Calcium - 381,000 ppm
Strontium - 7,390 ppm
