The highly porous aragonite is available in various grain sizes, with the smallest grains being less than one millimeter in size. The natural, round polished reef sand is perfectly suited for method of the "Deep Sand Bed" (DSB). But also hard corals and "difficult" plants, such as tall sea grass, grow particularly well in it. This makes aragonite sand suitable for digging animals such as gobies, crabs and sea cucumbers. Because it has something decisive which calcite or dolomite do not have: Its natural oolitic (egg-shaped) grain makes this sand pleasantly soft. With aragonite sand you create the best conditions in your saltwater aquarium so that its inhabitants feel well, thrive and stay healthy. Why oolitic sand is ideal for your aquarium ecosystem In the natural form we offer, aragonite is a thoroughly sustainable product. Every year, almost 2 billion kilograms of new aragonite are created in this way. It precipitates as a result of a biochemical process and floats above the Bahama Banks, where it sinks to the sea floor. Aragonite - unique sand from natureĪragonite is found as a purely natural product on the Bahama Banks, where it is formed during the metabolism of algae and bacteria.
