Abstract
A water filter for use inside of an aquarium which is characterized by the fact that filter cavity housing is removably attached to a sleeve unit which is in turn attached to the inside wall of the aquarium. When the filter material in the filter unit must be changed, the filter cavity housing may be removed from the sleeve unit which remains attached to the wall of the aquarium. The water current generating mechanism of the filter unit is also connected to the sleeve unit so that it does not have to be disconnected when the filter material is changed. The filter unit of the present invention is adapted for use with a cartridge type filter material in a preferred embodiment of the invention.
