An aquarium filtering system utilizing an immersible housing having perforations on two opposed surfaces, an external supply and take-up means for filter material. The immersible housing and the portion of the filtering system positioning the supply and take-up of filter material act jointly to form a structure for positioning the filtration system in an aquarium, and storing the filter material outside of the aquarium unless in use. A fluid conduit is provided in the immersed portion of the housing for introduction and/or removal of the aquarium medium. Guides are provided over the edges of the system in order to control motion of the filter medium, and overflow control is provided above the aquarium water level in the immersed portion of the housing.

An immersible aquarium filtration system comprising: (a) filtration medium supply structure for mounting adjacent an aquarium; (b) expended filtration medium storage structure for mounting adjacent an aquarium; (c) an immersible housing comprising: (1) a first opposed pair of side walls; and (2) a second opposed pair of perforated side walls, said opposed pairs of walls forming an immersible portion and an external portion extending laterally from the immersible portion to support said supply structure and said storage structure; (d) filtration medium positioning guides locating said filtration medium over perforations of said perforated side walls; (e) a fluid conduit independent of ambient fluid within said aquarium for controlling fluid level in said immersible housing, said immersible housing and filtration medium being structured so that the aquarium medium will only flow between interior and exterior of the housing by passing through the filtration medium; and (f) means for advancing filtration medium between the supply and storage structures over said guides.
