Aeration systems


Why Aerate?

Aeration is all about gasses. Aeration mixes the pond so that toxic gasses are efficiently released and life-giving oxygen readily replaces it. An aerated pond will be clearer, cleaner, and have less bottom muck than a pond without aeration.


The science behind it


A pond without aeration will become stratified into two very separate layers in the summer heat. This is because of the physical properties of water. As the sun warms the surface water, it becomes less dense and thereby lighter than the cool water below it. The line at which these two layers separate (similar to oil floating on water) is called the thermocline.

No Oxygen = No Life

The vast majority of water-cleaning organisms (aerobic bacteria & phytoplankton) in a pond use oxygen to drive their metabolic processes. Oxygen enters the water column almost exclusively through the surface of a non-aerated pond. Because the surface water does not mix with the water below, oxygen in the bottom layer quickly becomes depleted under stratified conditions, allowing toxic gasses to build up. Because no oxygen is available below, the pond's overall ecosystem will begin to suffer.

Nutrient Build-Up

Without water cleaning organisms on the bottom, any sediment, debris, and nutrients that enter the system fall to the bottom and accumulate. This layer on the bottom is what many refer to as "muck". Having an unwanted pile of muck as well as a toxic lower-layer in your pond will quickly cause major headaches including algae blooms, rampant weed growth, and fish kills.

Airmax® to the Rescue!

Our Airmax Aeration Systems utilize a shore-mounted air pump that delivers air to specialized diffuser plates that are located on the pond bottom. The resulting column of rising bubbles circulates water throughout the pond, eliminating the thermocline. With a fresh supply of oxygen, natural bacteria and phytoplankton go to work in the water column as well as on the bottom. Any excess nutrients in the system are metabolized, resulting in cleaner, clearer water and less muck. Results you can see in just 90 days!
