Aeration systems utilize a shore-mounted air pump that delivers air to specialized diffusers 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! Easy Installation with Options - Airmax Aeration Systems are the easiest and most versatile systems to install on the market.
