This aeration system makes use of a shore-mounted compressor that pumps oxygen-rich air to the pond's floor via a special diffuser. Oxygen is most commonly consumed at the pond bottom, making it the ideal destination. Rising bubbles also help to reduce pesky ice in colder climates, and even boost circulation.
As the bubbles ascend from the diffusers, they create a "boiling" effect that arouses considerable currents in the pond. This circulation helps stop water stratification. The extra oxygen and the shaking currents caused by the device help form a balanced and flourishing ecosystem.
