This filter system can\'t be beaten for value and guarantees clear water for ponds up to 4,500 litres (1,000 gallons). During operation dirty water is pulled into the solids-handling pump where it is then pushed up to the filter via pond hose (supplied). The dirt and debris in this water is caught by the filter sponges contained in the pond filter. Clean water is then returned to the pond.
