ABSTRACT:
A removable light-weight, apparatus for the aeration of a body of water or other liquid in a tank or a pool having a submerged liquid source or inlet port supplying a continuous or a sporadic stream of liquid into said tank, said aeration apparatus comprising an air induction tube extending between and communicating at its upper and lower ends respectively with the ambient atmosphere and the liquid stream, and support means for said tube, the reduced pressure along the stream of liquid drawing air from the atmosphere into the liquid in the tank. A conduit may be provided coupled to the outlet of the liquid inlet port, the lower end of said air induction tube being inserted through the tubular wall of said conduit so as to permit the air in the lower end of the air induction tube to communicate with the liquid moving through the conduit, said conduit preferably terminating in a filter or a diffuser.
