ABSTRACT:
A multi-faceted intake filter for an aquarium includes a top surface portion, a bottom surface portion and a plurality of side surface portions that collectively define a filter body is formed from a compressible foam. The intake filter also includes a bore that extends along a longitudinal axis of the filter body. The bore includes a first end exposed at the top surface portion that leads to a second end which terminates prior to the bottom surface portion. The bore is designed to receive an intake portion of an aquarium filter tube. Preferably, the bore is off-set from a central axis of the filter body. The off-set bore allows the intake filter to be placed in a wide range of aquarium configurations, with at least one of the side surface portions abutting a wall of the aquarium.
