Pond Aeration

We custom design aeration systems that we can install or provide a kit and guidance for you to install yourself. A well designed and maintained aeration system will properly oxygenate the entire water column preventing stratification (thermocline formation). Eliminating anaerobic zones and venting off toxic compounds such as ammonia and carbon monoxide minimizes the effects these natural compounds have on the ecosystem of the pond.

The size shape and bottom contours of the pond need to be considered when designing an aeration system. We use our experience combined with all of the technology available to us such as our bathymetric mapping service to create the best design possible for each lake and pond.

To fit your needs, budget and preferences we offer the following options to help you install a properly designed aeration system we offer several options to make this solution affordable to you.

  • Design a custom aeration system using detailed depth information we collect on your pond
  • Fully install the custom designed aeration system
  • Provide you with a custom designed aeration kit for you to install yourself to save labor costs

Aeration prevents stratification. This is where the water column forms layers where the warm top layer no longer mixes with the bottom cold layer of water. Anglers often refer to this as a thermocline. As the cold water remains trapped at the bottom, oxygen depletes until fish can no longer use this area to live. The lack of oxygen also causes a release of phosphates from the bottom composition which feeds algae growth. Other compounds such as ammonia and carbon monoxide build until the levels reach toxic levels. In the spring and fall the surface water temperatures change and when it comes close to the temperature of the bottom layer these two masses suddenly mix. Anglers refer to this phenomenon as a turn over event. A fish kill event can take place if the volume of poor quality water is great enough compared to the top layer of water.

Using bottom based laminar flow aeration, often called bubblers, we can prevent thermocline formation and eliminate problems associated with that phenomenon. Potentially toxic compounds are constantly vented off and oxygen is maintained through the entire water column. Only a bubblers system can mix the entire water column. So called aerating fountains claim to aerate the water but they only mix the top few feet of water which is already aerated from natural wave action. As oxygen is brought to the bottom of the pond, phosphates bind to the soils and the activity level of natural bacteria increases to digest the layer of muck on the bottom of the pond. As these nutrient sources are reduced, algae and other aquatic plant growth levels are reduced.

Here is an EPA guide on using techniques envolving pond bacteria.

A short list of the benefits of a properly designed, installed and maintained aeration system:
  • Eliminate stratification (thermocline formation) and the harmful conditions that develop
  • Improve gas and chemical exchange between the bottom and the surface
  • Increase usable habitat
  • Introduce oxygen into the water column
  • Release carbon dioxide from the water
  • Reduce hydrogen sulfide, ammonia, methane and other gasses created through normal natural bacterial action
  • Reduce the potential for fish kills
  • Increase the activity of the beneficial benthic organisms
  • Increase the fish carrying capacity of the pond
  • Reduce the nutrients available to the unwanted algae
  • Reduce chemical usage to control unwanted aquatic plant growth
  • Reduce phosphate levels by promoting removal from the water as oxygen and iron in the soil bind and trap the compound
  • Prevent stagnation
  • Reduce odors
  • Reduce planktonic algae levels
