A low pressure valveless floating aeration system for providing oxygen and circulation to a water impoundment, utilizing one or more floating elongate members supporting a substantially uniform assemblage of air diffusers spaced above the bottom of the impoundment. Air at a comparatively low pressure is supplied to said elongate members and thence to said air diffusers, such that a large number of tiny bubbles will rise up from the air diffusers through the water of the impoundment, bringing about a desirable amount of circulation in the water. Because the air diffusers are suspended from members floating on the water surface, the depth at which the diffusers are located can be made uniform, or the diffusers can be suspended at gradually decreasing depths at locations remote from the air supply.
