NAUTEX, also known as "coccolithic chalk" or Champagne chalk, is a natural sedimentary calcium carbonate that is 60 million years old. Its chemical formula is CaCO3. It is very popular among fish farm operators, fishing bodies of water, and any other institution committed to rebalancing water parameters.

Designed to oxygenate and halt the increase in organic sludge depth in bodies of water, NAUTEX treatment offers numerous advantages.
NAUTEX thus plays a major role in regulating pH and dissolved oxygen levels. In a short amount of time, the action of the chalk restores the ecological balance, promotes photosynthesis, and thus provides better oxygenation of the water.
NAUTEX works in two complementary ways: physically, by flocculating suspended solids, and biologically by breaking down organic matter in the sediment.
