Liquid aeration system and method

1. A system for aerating liquid within a liquid retention structure, comprising:

a main body having an outer wall;

a liquid delivery tube positioned within said main body;

a heating element proximate said liquid delivery tube;

a gas exchange chamber connected to said liquid delivery tube, said gas exchange chamber being in fluid communication with said liquid delivery tube; and

a pressure relief passage configured to relieve pressure underneath a layer of ice formed over the liquid within the liquid retention structure.

2. The system of claim 1 , wherein said pressure relief passage is formed through said main body.

3. The system of claim 1 , further comprising a flotation member radially extending from said outer wall.

4. The system of claim 1 , further comprising a pump in fluid communication with said liquid delivery tube, said pump being configured to pump liquid within the liquid retention structure through said liquid delivery tube and into said gas exchange chamber so that harmful gases contained within the liquid escape from the liquid and exit through said gas exchange chamber, while fresh air enters into said gas exchange chamber and is absorbed into the liquid within said gas exchange chamber.

5. The system of claim 1 , further comprising an extension member downwardly extending from said main body.

6. The system of claim 1 , wherein the system is electrically connected to an additional system for aerating a liquid within a liquid retention structure.

7. The system of claim 1 , further comprising a filter medium.
