| 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.

I claim:
1. An aquarium having two side walls, a bottom and two end walls, a sea current generator comprising:
- an airtight water chamber located in one end of the aquarium including a top, the water chamber including an opening into the aquarium extending across the bottom from one side to the other, the water chamber otherwise being enclosed and including a constant flow air pump means connected to the top of the water chamber for pumping air into said chamber and expelling water therefrom to elevate the water column in the aquarium and air valve means in a duct connecting the water chamber to atmosphere and actuating means for cycling the air valve from an open to a closed position whereby in its open position the air valve and duct exceed the capacity of the constant flow air pump and allows the elevated water column in the aquarium to move back into the water chamber through the said opening until the water levels stabilize, thereby creating a back-and-forth current of water within the bottom regions of the aquarium.
