15. The filter cartridge carrier of claim 14 , wherein the support frame includes a first frame section that defines the first side and a second frame section that defines the second side, the first and second frame sections being interconnected to one another at a hinged connection.

16. The filter cartridge carrier of claim 14 , wherein the tab has a generally flat construction defined by opposing primary planar surfaces, the opposing primary planar surfaces being oriented in a generally perpendicular direction relative to the one side.

17. A filter cartridge carrier for use in an aquarium filter housing, the filter cartridge carrier comprising:

a) a support frame including a first frame section and a second frame section interconnected to one another at a hinged connection; the first frame section and the second frame section being primarily open to allow aquarium water to pass therethrough;

b) a handle located at a first end of the support frame; and

c) a tab that spaces the carrier from an upright wall of the aquarium filter housing, the tab projecting outward from one of the first and second frame sections of the support frame in a transverse direction relative to the one frame section.

18. The filter cartridge carrier of claim 17 , wherein the tab has a generally flat construction defined by opposing primary planar surfaces, the opposing primary planar surfaces being oriented in a generally perpendicular direction relative to the one frame section.
