ABSTRACT:
A filtering apparatus for use generally in filtering the fluid of an aquarium. It consists of a clear housing that is submerged within the tank with this housing having both intake and discharge openings therein for the passage of fluid therethrough. This housing is further configured with a series of channels formed therein for directing the flow of fluid within the housing to the filter. A removable filter is mounted within the housing and is coupled to the discharge opening which, in turn, is coupled to a pump. The housing is openable so that access to the filter is provided when the filter needs to be replaced. Also, adjacent each intake opening is a flap to permit only one-way flow across the intake openings and into the housing.
