Enjoy your pond - your pond manager FiltoMatic CWS 25000 does the work. This intelligent pond filter not only cleans ponds up to 25 m³, with fish up to 12.5 m³, but also gets rid of its own dirt inside. Thanks to the permanent temperature measurement of the water, the control unit starts the integrated 24 watt UVC clarifier with reflector technology and its patented cleaning function independently and as required. This enables electricity savings of up to 40%. The intelligence pays off. The control unit also automatically activates the sludge pump, which conveys the dirt out of the filter. This also reduces the growth of thread algae through permanent nutrient discharge. Cleaning the outside of the filter sponges is almost as easy and clean - without getting your hands dirty. Trust in OASE quality, because you receive a total of up to 3 years guarantee - 2 plus 1 year requirement guarantee as well as the OASE clear water guarantee.
