Nautex in 25kg bag - Coccolithic chalk for pond

Useful for the management and the fight of the phenomena of eutrophication of organic pollution. Annual maintenance recommended.

💡 Dosage: 150 to 200g/m² for shock treatment - 80 to 100g/m² for maintenance.

NAUTEX, also called "coccolitic chalk", or Champagne chalk, is a natural calcium carbonate of sedimentary origin that is 60 million years old. Its chemical formula is CaCO3. It is very popular among fish farmers, fishing lakes and any other institution concerned with rebalancing the parameters of the water.

Designed to oxygenate and stop the increase in the height of organic mud in bodies of water, a NAUTEX treatment has many advantages.

The NAUTEX will thus play the main role in regulating the pH and that of the dissolved oxygen content. Thus in a minimum of time, the action of the chalk makes it possible to restore the ecological balance, promotes photosynthesis and thus provides better oxygenation of the water.

NAUTEX acts in two complementary ways: physically, by flocculating matter in suspension and biologically by degrading the organic matter of the sediment.
