ABSTRACT:
An external aquarium filter of the canister type formed of a flat, substantially cylindrical container with a screw-top cover. Both inlet and outlet ports extend through the cover. The inlet port continues with a depending tube to be in flow communication with the bottom of the container and the outlet port is in flow communication with the top of the container. A sheet of foam filtering material is supported in the middle of the container to define a contaminated water chamber beneath the filtering material and a clean water chamber above the filtering material. An air pump or water pump can be used to provide the continuous flow of water through the filter. The water pump can be integrally formed on the cover and include an encapsulated stator, whose housing is integrally molded with the cover. A magnetically coupled impeller is positioned within the outlet flow path to aid in the flow of water through the filter.
