Dry Aragonite Suger Sized Sand

Create a flawless, natural-looking foundation for your marine or reef aquarium with CaribSea Aragamax Sugar-Sized Dry Aragonite Sand. Also known as "oolitic" sand, this super-fine substrate (0.25 - 1.0mm grain size) is renowned worldwide for its incredible purity. It is intentionally engineered to be completely free of harmful impurities such as ash, metals, pesticides, and silica, ensuring a safe and pristine environment for your delicate fish and invertebrates from day one.

Beyond its stunning bright white aesthetic, this sugar-sized aragonite provides immense biological and chemical benefits. It naturally buffers your water chemistry by slowly delivering essential calcium, carbonate, and trace elements to maintain a stable, healthy pH. Because of its remarkably fine, smooth, and round grains, it is the absolute perfect choice for shallow static beds. It is incredibly gentle on soft-bellied bottom dwellers like rays and sharks, and it easily passes through the gills of sand-sifting gobies and invertebrates without causing irritation.
