Nautex in 10kg bucket - Coccolithic chalk for pond

Useful for managing and combating eutrophication caused by organic pollution. Annual maintenance recommended.

💡 Dosage: 100 g/m² per application, 2 applications per year (spring and autumn) for maintenance - 150 to 200 g/m² for shock treatment (heavily silted pond, first year), then switch to maintenance.

NAUTEX, also known as "coccolithic chalk" or Champagne chalk, is a natural calcium carbonate of sedimentary origin dating back 60 million years. Its chemical formula is CaCO3. It is very popular among fish farm operators, fishing waters, 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 minimum amount of time, the action of the chalk restores 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.
