9. A filter, comprising:
-
a filter housing configured to mount internally to an aquarium; a removable filter cartridge positioned within the filter housing, the filter cartridge defining first and second chambers within the filter housing; and a pneumatic intake assembly arranged to create fluid flow from the aquarium to the first chamber to fill the first chamber with unfiltered water, the unfiltered water reaching a first water level during operation of the filter; wherein only head pressure from the unfiltered water is utilized to generate fluid flow through the filter cartridge, the head pressure urging the unfiltered water through the filter cartridge in a generally horizontal direction. - View Dependent Claims (10, 11, 12, 13, 14, 15)
