A system for super-oxygenating water is provided that includes an oxygen generator for generating first oxygen, a combining unit coupled to the oxygen generator for combining the oxygen with the water, a diffusion chamber coupled to the combining unit for receiving the combined water and oxygen and manipulating them into a vortex so as to cause the oxygen to diffuse into the water and yield first oxygenated water, a source of second oxygen, a plurality of cones in communication with the source of second oxygen and configured to receive the first oxygenated water and spin the first oxygenated water to combine it with the second oxygen received from the source to yield super-oxygenated water. The spray nozzle is sized and oriented such that the vortex generated in the diffusion chamber is adequate to diffuse the oxygen into the water as they travel through the vortex and exit the diffusion chamber.
