OOLITIC ARAGONITE 4.5 Kg – Oolitic Aragonite Sand from the Bahamas for Marine and African Cichlid Aquariums
Oolitic Aragonite 4.5 Kg is a premium, sustainable natural substrate made of biogenic oolitic aragonite sand sourced from the crystal-clear waters of the Bahamas. Composed of up to 98% pure calcium carbonate, this sand features smooth, egg-shaped grains with no sharp edges, no odors, and no dust. As a naturally renewable product, it’s perfect for marine, reef, and African cichlid aquariums, offering superior quality for a thriving aquatic environment.
This aragonite sand not only provides exceptional buffering capacity to maintain a stable pH around 8.2 but also offers a massive surface area (over 1 million cm² per kilogram) for beneficial bacteria to colonize, promoting the reduction of ammonia, nitrites, and nitrates. With its fine, uniform grain size, it’s ideal for reef tanks, plenum systems, refugiums, and any setup that demands a chemically safe, stable, and natural substrate.
