Subsurface Aeration:  Air-Flo Model

The Air-Flo system is what most folks call a "Bubbler." The Air-Flo approaches aeration from the bottom up by using a shore-based air compressor to supply diffuser plates located at the pond's deepest points, where columns of micro-bubbles are sent upward. Water molecules attach to these micro-bubbles, creating an upwelling of relatively Oxygen-poor water rising to the Oxygen-rich surface. The migration of this water creates a continuous mixing of the pond's water to gradually raise the entire pond's Dissolved Oxygen (DO) content. Increased DO helps in oxidizing the bottom organic layer of the pond, reducing excess nutrients and actually helping to reduce bottom sediments.  With "Bubblers," such as the Air-Flo system, the deeper the water, the better. They are at their most effective in deep water of 10 feet or more, but their effects can be helpful in water of 6 - 8 feet in depth.
