Abstract: The present invention provides an aquarium filtering system having a pump housing and a filter assembly which is detachably secured to the pump housing for cleaning or replacement. The pump housing includes two conduits which register with and telescopically receive two conduits on the filter assembly as the filter assembly is connected to the pump housing thus fluidly connecting the pump housing and filter assembly together. A yoke is slidably mounted to the pump housing and movable between a locking and unlocking position. In its locking position, the yoke engages two locking tabs on the filter assembly thus mechanically attaching the filter assembly to the pump housing. Conversely, in its unlocking position, the yoke enables the filter assembly to be removed from the pump housing.

Abstract: The present invention provides a fluid filtering system for an aquarium having a tank in which water and marine animals are contained. The filtering system includes a pump, a filter element and a valve assembly fluidly connected therebetween. In addition, a pump actuator is movable between a first position and a second position in which the pump inlet and outlet are inverted. Actuation of the valve assembly to a first position and with the pump actuator in its first position allows the pump to pump water from the aquarium tank under pressure to and through the filter element after which the cleaned water is returned to the aquarium tank. Conversely, with the valve assembly and pump actuator in their second positions, the pump draws water from the aquarium tank, through the filter element and the cleaned water is then returned by the pump to the aquarium tank. Pressure pumping, i.e.
