The system generally includes a container and a centrifugal pump adapted selectively operate in either an aerating mode to provide oxygen to the aquatic life or a pumping mode in which the water in the tank is replace with fresh water. The pump is designed to be self priming, thereby allowing a system that is substantially self regulating and operating without the necessity of electronic controls.
