The present invention generally provides a portable system for maintaining aquatic life that require oxygenated water, such as fish, shrimp, other marine animals, microbial populations, plant life and combinations thereof. 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.

[ What is claimed is:] [1.] A system for maintaining an aquatic environment, comprising:(a) a water containment member made of a buoyant material;(b) a centrifugal pump disposed within the water containment member, the pump having a pump inlet directed generally upward from a horizontal plane and a pump outlet;(c) a water inlet channel selectively communicable with the pump inlet and a water source; and(d) an outlet channel communicable with the pump outlet, the pump being adapted to aerate water in a first mode where the pump inlet is at least partially open to a gas source and the pump inlet is at least partially open to a water source and the pump being adapted to flow water in a second mode to raise or lower a water level in the water containment member.
