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

Designed to oxygenate and prevent the increase of organic sludge height in water bodies, a treatment with NAUTEX offers many advantages.

NAUTEX thus plays the main role in regulating pH and dissolved oxygen content. In a short time, the action of the chalk restores ecological balance, promotes photosynthesis, and provides better oxygenation of the water.

NAUTEX works in two complementary ways: physically, by flocculating suspended matter, and biologically by breaking down the organic matter in the sediment.
