Apparatus for aerating water includes a water accelerator generally in the form of a propeller, and a motor for rotating the accelerator. An airway delivers small amounts of air to an onlet on a water intake side of the accelerator. Rotation of the accelerator draws air from the airway outlet and disperses the air into the water. The accelerator and the airway outlet are preferably located in a housing having a water inlet for supplying water to the intake side of the accelerator, and a water outlet providing for the exhaust of aerated water leaving the accelerator.
