Description

Aquipond Nautex is coccolith chalk, also known as Champagne chalk: a natural calcium carbonate (CaCO₃) of sedimentary origin, 60 million years old. It regulates pH and dissolved oxygen and slows the build-up of organic sludge in ponds and lakes.

How does Nautex work?

Made from marine coccolith chalk, Nautex works without mechanical dredging, in three complementary ways: biologically, it stimulates the aerobic bacteria that break down sediment; physically, it flocculates fine suspended particles; chemically, it acts as a pH buffer, limiting acidification and promoting oxygenation at the bottom of the pond.

Benefits for your pond or lake

  • Less sludge without dredging: aerobic bacteria break down the sediment.
  • More oxygen available for aquatic wildlife.
  • pH and odours under control: more stable, more pleasant water.
  • More transparent water thanks to the flocculation of suspended matter.
  • Greater phytoplankton diversity: a better-balanced ecosystem.

How to use

123Prepare50 kg per 100 LSpreadwatering can or pumpPlanspring or autumnAvoid frost and very hot weather

Preparation: mix 50 kg of powder in 100 L of water and stir until you get a smooth white liquid, known as "Nautex milk".

Application: on small areas, spread with a watering can, covering the surface evenly; on large areas, use a motor pump from the bank or from a boat.

Ideal periods: spring (March to May) and autumn (September to November). Avoid periods of frost and very hot weather.

What dose for my pond?

Nautex is dosed according to the surface area of the water: 80 to 100 g/m² for annual maintenance, to keep the balance and prevent sludge build-up; 150 to 200 g/m² for corrective treatment, for a silted-up or degraded pond.
