The clear water expert: Pressure filter with first-class filter performance and special functions, available either individually or as a set with matching pump. Clear water guarantee: effective nutrient decomposition thanks to large filter surface and integrated UVC clarifier for the removal of pathogens, floating algae and turbidity. All operating elements are integrated in the cover. This allows the filter to be sunk into the ground at ground level and blends harmoniously into any garden landscape. Practical: Cleaning takes place from the outside without opening the lid, suitable for ponds up to 30 m³.
