A Substrate to Help Maintain a Balanced pH

  • Smooth, Fine Oolitic Sand
  • Up to 98% Pure Calcium Carbonate
  • Ideal for African Cichlid Aquariums
  • Also Safe for Saltwater Aquariums


Bahamian Aragonite Aquarium Sand is the ideal substrate for African Cichlid aquariums. It is a pure Oolitic Aragonite sand collected from the crystal-clear oceans of The Bahamas. This aquarium sand has unsurpassed buffering capability and helps maintain a natural pH balance of 8.2 without the constant addition of chemicals. One kg of Oolitic Aragonite Aquarium Sand offers over 1 million sq. cm of surface area providing a huge space for housing ammonia, nitrite, and nitrate reducing bacteria. Oolitic Aragonite Sand can also be used for saltwater reef tanks, FOWLR tanks, and refugiums.



Rinse well in a bucket using clean water. Do not use soap or other cleaning agents. Continue to rinse material until overflow water turns from a milky to light cloudy appearance. Any remaining cloudiness will disappear after a few hours of pump operation.

For best results when setting up a new aquarium, place rinsed sand into empty aquarium then carefully fill with water. Start filtration system. Wait until the water is clear enough to see the back of the aquarium and the chemical / pH / temperate are stable before adding fish and invertebrates.

With existing aquariums, rinse substrate as above and mix in small amounts into the established sand-bed over a period of several days. When using aragonite for African cichlids or other freshwater applications, note that a slight cloudiness may persist until the aquarium cycles due to high rates of calcium carbonate dissolution.
