Abstract
Pond filters are generally discussed herein with particular discussions extended to pond filters having a filter mode and a backflush mode. In accordance with aspects of the present invention, the pond filters incorporate a flow controller positioned inside a housing capable of being manipulated using a control knob located on the outside of the housing. The control knob moves a flow gate to direct incoming fluid flow to flow along a first direction for filtering or a second direction for backflushing the filter cartridge.
