  • Aquarium and waterfall system
    Patent number: 4836142
    Abstract: An aquarium system having a plurality of aquarium tanks which employs waterfalls between the tanks to enhance the display of marine life. Each one of the aquarium tanks is adapted to contain marine life up to a different predetermined upper water level. The water is directed to form waterfalls which carry it from aquarium tanks having higher upper water levels into aquarium tanks having lower upper water levels. A transfer system pumps water from the tank having the lowest upper water level to the tank having the highest upper water level thereby providing a constant flow of water for the waterfalls.
