ABSTRACT:
An aquarium system for containing water and aquatic life therein is disclosed that includes a reservoir and an aquarium that is mounted generally above the reservoir. The aquarium has an outlet in liquid communication with the reservoir through an outlet conduit that includes a discharge mechanism, preferably an inverted U-shaped siphon conduit, that periodically discharges a portion of the water from the aquarium to the reservoir therethrough once the water has reached a maximum water level. A pumping mechanism pumps water from the reservoir up to the aquarium through an inlet conduit that is in fluid communication with the reservoir and an inlet of the aquarium. As such, when the water reaches the maximum level in the aquarium, the siphon conduit substantially fills with water which begins to flow out through the outlet conduit, drawing a portion of water from the aquarium rapidly through the outlet conduit until the water in the aquarium reaches the open bottom end of the siphon conduit. Air in the aquarium thereafter enters the siphon conduit to break the siphon. Water leaving the output conduit enters a filter means to filter and clean the water before it is returned to the aquarium by the pump. An embodiment emulates the current of a river, wherein the aquarium takes the shape of an elongated, substantially transparent tube or trough. A wave surge mechanism may be included for producing periodic wave surges in the aquarium.
