A method for super-oxygenating water is provided. The method includes combining water and first oxygen, manipulating the combined water and first oxygen into a vortex so as to cause the first oxygen to diffuse into the water and yield first oxygenated water, combining the first oxygenated water with second oxygen, and passing the first oxygenated water/second oxygen combination through a cone system that spins the combination to yield super-oxygenated structured water. Water and oxygen are directed through a spray nozzle and manipulated into a vortex as the water and oxygen enter a diffusion chamber. 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.
