For ponds that experience a fluctuation in the water level, a floating aerator that can be easily moved is the solution to address the variations in water height. All three of Fresh-flo’s aerators: model AE-F3 which is ⅓ hp with a 225 gallons/minute capacity, model BE-F3 which is ½ hp. with a 340 gallons/minute capacity, and model BTE-F3 which is 1 hp. with 550 gallons/minute capacity can be manufactured as floating aerators as well. Special high density polyethylene floats, filled with polyurethane foam, are added to make them floating aerators. The tube length is 24".
