The revolution in water conditioning
The unique “dry water conditioner” combines stabilizing biological filtration with effective and quick pollutant removal of water conditioning.
Pollutant utilizing bacteria remove pollutants such as ammonium and nitrite from the water already shortly after the first contact with water. Sludge is decomposed faster, and thus a critical pollutant reservoir is quickly rendered harmless. The biological equilibrium is stabilized and maintenance intervals become longer.
