Abstract
A media reactor aquarium filter incorporates a simple design and allows simple media replacement. The filter includes co-axial inner and outer tubes. The outer tube includes a mounting feature and the inner tube holds the media and is removable without disturbing the outer tube. A pump at the base of the filter pumps water into the inner tube through ports at the base of the inner tube and up through the inner tube, and this through the media. The filtered water then flows though the top wall of the inner tube and down between the inner and outer tubes, and back into the aquarium. The inner tube is rotatable to vary the alignment of the ports to adjust the water flow rate through the filter.
Claims11
An aquarium filter comprising:
- an elongated outer body;
- a removable smaller elongated inner body residing inside the outer body;
- a filter pump residing at a first end of the outer body in fluid communication between an aquarium and the inner body;
- a filter media residing inside the inner body;
- transfer ports in the inner body separated from the first end by the filter media and allowing a flow of filtered water between the inner body and the outer body;
- and
- outlet ports in the outer body allowing the flow filtered water to be released into the aquarium
An aquarium filter comprising:
- a cylindrical outer tube attachable to an aquarium;
- a removable and rotatable smaller cylindrical inner tube residing inside the outer tube;
- media residing inside the inner tube and replaceable by removing the inner tube from the outer tube;
- a pump residing at a bottom end of the filter in fluid communication between the aquarium and the inner tube through adjustable inlet ports between the pump and inner tube;
- transfer ports in the inner tube opposite the bottom end allowing a flow between the inner tube and the outer tube;
- and
- outlet ports at the bottom of the outer tube allowing filtered water to be released into the aquarium.
An aquarium filter comprising:
- a cylindrical outer tube attachable to an aquarium;
- an outer tube base plug having outer tube inlet ports;
- a removable and rotatable smaller cylindrical inner tube residing inside the outer tube;
- media residing inside the inner tube and replaceable by removing the inner tube from the outer tube;
- a pump residing at a bottom end of the filter in fluid communication between the aquarium and the inner tube;
- transfer ports in the inner tube opposite the bottom end of the filter allowing a flow between the inner tube and the outer tube;
- outlet ports at the bottom of the outer tube allowing filtered water to be released into the aquarium;
- and
- the inner tube rotatable with respect to the outer tube and including an inner tube base plug having inner tube inlet ports, alignment of the inner tube inlet ports with the outer tube inlet ports adjustable by rotating the inner tube to control water flow through the aquarium filter.
