THE WORLD'S BEST AERATOR: The most effective, quiet, efficient and easiest to install. Aeration adds valuable oxygen to a pond or lake, particularly on the pond's bottom where muck and organic debris accumulates. A properly sized aerator works from the bottom up to ensure all areas of the pond are circulated and saturated with dissolved oxygen leaving you with a cleaner, clearer and balanced pond.


Airmax® Aeration systems utilize a shore-mounted air pump that delivers air to specialized diffuser plates that are located on the pond bottom. Resulting in a column of rising bubbles that circulates water throughout the pond, eliminating a change in temperature or thermocline. With increased oxygen and added natural bacteria, any excess nutrients in the pond or lake are metabolized, resulting in cleaner, clearer water and less muck. Results you can see in just 90 days!
