Improving Your Pond with Aeration

Pond aeration systems circulate the bottom layers of your pond to the top, preventing the pond from becoming stagnant and keeping water oxygenated. Unlike fountains, which shoot water up and out of the water, aerators are often described as “bubblers”. These units sit at the bottom of the pond and shoot up air bubbles, which can be seen at the surface of the water. Though more subtle than a fountain, it provides more oxygen to the entire pond than any standard fountain ever could.

An aerator may enhance chemical treatment, but should never replace it. Combining the use of an aerator with colorant and bacteria can help prevent weed and algae growth, pond turnover, and fish kill. Using pond aeration and pond chemicals together will make for a complimentary pond maintenance plan and ensure you are getting the most out of both efforts.

For example, the use of pond bacteria is an important step for preventative pond maintenance. Pairing our dosing of pond bacteria with aeration doubles the effectiveness of the bacteria. Pond bacteria products have been known to react more rapidly and for a longer period when a pond has an aerator.

Weeds like duckweed thrive in nutrient rich, stagnant environments. Adding an aerator to your pond will help create surface movement, which will create an environment duckweed typically doesn’t like. However, there are many other weeds that could care less if the water is still or moving, and for these weeds our techs will use other methods of chemical treatment.

After reading about these benefits, you’ve decided to purchase an aerator…now what? Here’s what our office needs to know to help you choose what model to go with:

  • Where you want to place your unit within the pond.
  • Do you already have electrical set up? If you do not, call your electrician to arrange installation. This is required for both fountains and aerators!
  • Roughly how far will the unit be from your electrical source? This will determine cord length needed.
  • The voltage of your electrical. This will determine what models are compatible with your setup. Example: many of our units are 115 or 120v.
  • Water depth in your chosen location. Some models are more suitable for certain depths.

Once your model is chosen, we will have it shipped directly to you with detailed instructions for set up. If setting up the unit isn’t doable yourself, check with your local electrician to see if they can offer services or references.

Contact our office if you would like more information or are interested in purchasing a unit.
