Abstract

An improved canister-type aquarium filter design which includes, in various combinations, a motor which is contained within the canister, a discharge tube arranged approximately along the longitudinal axis of the canister, a pump section from which water exits from the top, a cover securing device which applies force to the top of the cover, a clamp arrangement for securing tubes to ports on the cover, and an adjustable mounting system for mounting the filter to an aquarium frame. The improved design provides easy access to the filter cartridge, improves efficiency, and eliminates the need for flexible hoses traditionally used to connect the filter to an aquarium.
