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.
