ABSTRACT:
An aquarium filter assembly (10) which comprises a filter body (12) made of an open celled foam material which supports a culture of aerobic bacteria which removes toxic ammonia from aquarium water in which it is immersed. The filter body (12) substantially defines a closed cavity (14) and a passageway (30) extends through the open celled foam material into cavity (14) for receipt therewithin of an aerator lift tube (32) of a cross sectional dimension substantially less than that of the cavity (14) leaving open space in the cavity (14) and to draw aquarium water therefrom to cause aquarium water to freely flow into the open space of the cavity substantially uniform through the entire amount of open celled foam material of the filter body (12). The aquarium filter assembly also includes a means for mounting (43) the filter body (12) within the aquarium but spaced from interior surfaces thereof to permit unobstructed flow through substantially the entire filter body (12). Further, including a method to do the same.
