Self cleaning aquarium system

An aquarium system for containing water and aquatic life therein, comprising:

• a reservoir;
• an aquarium having an outlet in liquid communication with the reservoir through an outlet conduit, the outlet conduit including a discharge means for periodically discharging a portion of the water from the aquarium to the reservoir therethrough, the discharge means including an inverted generally U-shaped siphon conduit having an open bottom end in fluid communication with the outlet conduit, the siphon conduit adapted to establish a siphon when the water level in the aquarium reaches a predetermined maximum level, the siphon conduit including at least one air aperture that may be selectively covered to adjust a minimum water level in the aquarium;
• and
• a pumping means for pumping water from the reservoir to the aquarium through an inlet conduit that is in fluid communication with the reservoir and an inlet of the aquarium;
• whereby with the aquarium fixed generally higher than the reservoir, when the water level reaches the maximum level in the aquarium, the siphon conduit substantially fills with water to draw the portion of the water from the aquarium rapidly through the outlet conduit until the water level in the aquarium reaches the open bottom end of the siphon conduit, air in the aquarium thereafter entering the siphon conduit to break the siphon.
