Scott,
Not too many studies exsist on the effect aeration has on Fecals and Total Fecals, but through experience (Wet N Wild) in Orlando and a lakefront swimming area in Maryland, we have experienced fecal numbers to drop below detectable levels.

The Maryland swim area runs at night. During the day the lifeguards take the CoActive AirStations that are connected to BottomLine Tubing and move them out of the swim area. At closing they replace them.

Wet N Wild we aerate the entire lake where they have the Knee Ski area.
