Abstract

See full text

A water circulation pump pre-filter unit (PFU). The PFU is submerged and provides structure to camouflage the system to give a natural and aesthetic look. The PFU comprises at least two cleaning systems: (1) biological cleaning mechanism; and (2) an internal self-cleaning mechanism. Specifically, the PFU comprises several filtering surfaces that form a repository for pond debris on which fish and other aquatic creatures feed, i.e., the biological cleaning mechanism. These filtering surfaces of the PFU also provide a protective barrier that prevents large debris from entering the circulation pump. The internal self-cleaning mechanism is a spray wash water source mechanism used to clean the PFU without removing the PFU or fish from the pond or entering the water. Together these features improve the quality of the water in the pond and extend the life of a pump.
