Nautex (powder)
the standard mineral treatment for all bodies of water

Nautex is the flagship product of the TASO line for the biological maintenance of water bodies, particularly in fish farming and large-scale applications.
Derived from marine-origin coccolithal chalk, this natural calcium carbonate (CaCO₃) simultaneously improves water quality and sediment dynamics.

Its action is part of a logic of controlled biostimulation, by supporting the natural processes of mud degradation and physico-chemical regulation of the environment.

The 5 Key Benefits
by Nautex

  • Gradual reduction of sludge through biostimulation
    Nautex promotes the activity of aerobic bacteria responsible for the degradation and mineralization of organic sediments, without the need for mechanical dredging.
  • Rapid Water Clarifier
    Through flocculation, this product binds fine suspended particles together, visibly improving water clarity.
  • Fish Health and Performance
    A 100% natural product, Nautex helps improve fish welfare, reduce stress, and support pond productivity.
  • Chemical regulation of the environment
    Calcium carbonate acts as a buffer for pH, limiting acidification and promoting better oxygenation, particularly at the bottom of the pond.
  • Excellent cost-effectiveness
    Nautex offers one of the best cost-performance ratios on the market for treating large areas and high volumes.
