A pond filter system is a device that is used to filter the water in a pond. The filter system is usually made up of a pump, a filter, and a filter cartridge. The pump is used to pump water from the pond to the filter. The filter removes debris and other impurities from the water. The filter cartridge is the part of the filter system that is replaced when it becomes clogged with debris.
