Aquatik Arabase Aragonite Sand 10kg

Aquatik Arabase Aragonite Reef Sand

Bring the foundation of the ocean into your aquarium with Aquatik Arabase Aragonite Reef Sand — a premium, sustainably sourced substrate made from 100% pure Caribbean aragonite. Designed for both reef and cichlid aquariums, Arabase provides the perfect balance between natural beauty, biological function, and long-term stability — exactly what your marine ecosystem needs to thrive.

Naturally Perfect Chemistry

Aragonite is the same mineral found in coral skeletons and tropical reef beds, making it the ideal substrate for marine environments. The 0.4–0.8 mm grain size ensures a fine yet stable texture that allows water to flow through the upper layer of the sand bed, preventing compaction and supporting oxygen exchange. This creates an ideal habitat for nitrifying and denitrifying bacteria, which play a crucial role in biological filtration and the natural nitrogen cycle.

By gradually dissolving over time, Arabase naturally stabilizes pH and alkalinity, helping maintain conditions that mirror the ocean’s chemistry. This buffering capability reduces stress on fish and corals while promoting strong skeletal growth and vibrant coloration.

Sustainably Harvested & Eco-Responsible

Aquatik Arabase is sourced from the only self-replenishing, renewable marine aragonite resource in the world, located in the pristine Caribbean. Unlike mined alternatives that deplete natural habitats, this renewable source is continuously replenished through natural oceanic processes, ensuring minimal environmental impact and long-term ecological balance.

Our commitment to sustainability extends beyond sourcing — every bag of Arabase is packaged in eco-friendly, recycled materials, reducing waste while delivering uncompromising quality.

High Quality Reef Sand

Whether you’re building a living reef, a fish-only marine system, or a high-pH cichlid environment, Aquatik Arabase is the perfect sand to use. The consistent grain size of 0.4–0.8 mm provides the perfect substrate depth for burrowing species, coral placement, and stable rockwork. Its high surface area encourages beneficial bacterial colonization, while its ultra-clean preparation minimizes cloudiness and speeds up tank cycling.

Aquatik Arabase is reef-safe and free of impurities, ensuring that nothing unwanted enters your aquarium. Simply rinse lightly before use, add to your aquarium, and watch as your water clears to reveal a bright, natural seabed that enhances light reflection and brings out the colours of your fish and corals.
