Abstract: A sea current generator aquarium including an air fight water chamber located at one end of the aquarium with a first opening into the aquarium extending across the bottom of the chamber. At the opposite end of the aquarium between the end wall and a horizontal divider wall is a second opening into an upper chamber which is open to atmosphere. A constant flow air pump is connected to the water chamber for pumping air in and expelling water out of the first opening into the aquarium and then into the upper chamber. An air valve which cycles open or closed, connects the water chamber to atmosphere and in its vented position, the valve dumps the capacity of the pump and allows the elevated water column in the aquarium and upper chamber to move back into the water chamber through both openings until the valve cycles closed thereby creating a back and forth current of water within the bottom regions of the aquarium.

Abstract: A sea current generator aquarium including an air-tight water chamber located at one end of the aquarium with an opening into the aquarium extending across the bottom of the chamber. A constant flow air pump connected to the top of the water chamber for pumping air therein and expelling water therefrom out of said opening into the aquarium and an air valve positioned in an duct connecting the top of the water chamber to atmosphere in an actuating means for cycling the air valve from an opened to a closed position whereby in its opened position, the air valve and duct exceed the capacity of the pump and allow the elevated water column in the aquarium to move back into the water chamber through said opening until the water level is stabilized and thereby creating a back and forth current of water within the bottom regions of the aquarium.
