Pond & Lake Aeration Systems

Even though a landscape water feature such as a pond or a lake is made up mainly of oxygen, water is also an essential part of any water source. Ponds and lakes that do not contain enough oxygen may get overrun by algae, or even worse, anaerobic microbes. Various aeration systems ensure that water is oxygenated sufficient to stay clean and clear.


Perhaps the most visible method to maintain an aerated pond or lake, fountains force streams of water up into the air and bring them crashing to the rest of the water feature. This makes agitation on the water’s surface and as a result, folds oxygen to the pond or lake. The pump of this fountain also cools water from deeper underneath the surface, ensuring that water not affected by surface agitation is oxygenated.


While fountains push water into the air, bubblers push air to the water. Sitting in the bottom of the pond or lake, bubblers feature tubes or pipes that run to the surface along with an air compressor. This compressor forces air from the surface through little holes at a diffuser device that produce bubbles in the water, oxygenating the water as the bubbles burst.

Pump and Cascade

While fountains circulate water, they also make a lot of noise and produce a spectacle that isn’t suitable for water features. A quieter and less conspicuous means to oxygenate water is by way of a pump and cascade system. Pumps pull water in the bottom of a river or pond and push it out in the top, allowing otherwise stagnant water a chance for oxygen in the surface.

Axial Flow Pump

The axial flow pump system consists of a large propeller that spins together with this water, forcing it down and pushing the water surrounding it around the surface. Axial flow pumps can reach up to 15 feet in diameter and also remainder on a floating platform which makes them suitable for medium and large sized lakes and ponds.
