  • Patent number: 5205237
    Abstract: Method and apparatus for providing an enhanced environment for supporting aquatic life includes an open container containing a body of water and an oxygen collecting canopy overlying a portion of the body of water and having peripheral edges which extend into the body of water. Oxygen is supplied to the body of water near the bottom of the container directly beneath the canopy so that the oxygen will rise through the body of water and into the canopy to maintain the canopy filled with oxygen. Water is recirculated from the container through the canopy to oxygenate the water and then returned to the container. At least a portion of the recirculating water is directed through one or more filters and zeolite containing tanks or trays prior to passing through the canopy and back into the container. Also, the recirculating water is dripped through open air to remove carbon dioxide from the water and increase the pH of the water.
