Aquarium filtration apparatus having a generally trough-shaped filter housing, the rear wall having a bracket portion for hanging on an aquarium, an impeller assembly having a drive magnet being positioned within the bottom of the filter housing with a motor assembly coupled to the undersurface of the bottom with a power driven magnet on the motor assembly in spaced proximate relation to effect magnetic coupling with the magnet of the impeller assembly. An intake assembly is provided in fluid communication with the impeller assembly and with the aquarium water for drawing water from the aquarium into the filter housing. In a first embodiment, the intake assembly is an intake tube having a portion within the filter housing. In a second embodiment, the intake assembly includes a filter chamber within the filter housing in fluid communication with the impeller assembly with an intake tube coupled to the filter chamber for drawing water from the aquarium into the chamber. A top cover is provided with a float having an indicator portion extending through the cover which is viewable when the water level rises to pivot the float. A filter cartridge may be utilized or filtration media may be retained between removable platforms.

Aquarium filtration apparatus

Aquarium hood apparatus having a base member with an aquarium filtration housing supported in partially depending relation to the base member, the housing having side walls, end walls, a bottom and an open top with a partition within the housing spaced from one end wall defining a water exit chamber for discharging water through an opening in the one end beneath the plane of the base member, the partition having the upper edge thereof spaced below the open end of the housing. A disposable filtration cartridge is disposed longitudinally between the partition and the other end wall to define a first fluid receiving chamber and a cleansed fluid chamber, the latter being in fluid communication with the first chamber, the height of the partition permitting overflow from the fluid receiving chamber into the first chamber in the event of clogging of the filter. A pump mounted to the surface of the base member draws fluid through a siphon tube through an inlet tube into the fluid receiving chamber, the housing being provided with a frictionally engaging cover plate to seal the open end thereof. The pump may be either directly coupled or magnetically coupled to the impeller thereof. A cover encloses the filtration apparatus, the cover also containing lighting means.
