Benefits of subsurface aeration:

  • Helps keep the water clear of algae and other organic matter
  • Promotes healthy oxygen levels for fish growth and sustainability
  • Helps evenly distribute oxygen and water temperature
  • Creates a hole in the ice in the winter which allows toxic gases to release preventing fish kill

Some Things to Consider

  • HIBLOW recommendations are general guidelines for selecting a pump.

  • For depths greater than 6′, you may want to consider bumping up to the next size pump to offset the loss of air from the increase in pressure.

  • If you have an odd or kidney shaped pond, it may be advisable to contact a pond distributor for guidance as you may need multiple diffusers to properly mix and aerate the whole pond.

  • If breeding specific types of fish, we would recommend consulting with an aquatic specialist before selecting a pump as certain breeds require different levels of oxygen.

Aeration System Recommendations for Best Results

  • Keep the pump covered and, in the shade, and allow for enough air circulation around the pump.
  • 1/2″ ID tubing/ weighted line is suggested for distances between 50′-100′ and 3/4″ ID beyond 100′.
  • You may consider using a “Y” connection instead of a “T” connection when splitting the line for multiple diffusers to reduce backpressure.
  • Use medium bubble diffusers to limit backpressure and increase air flow. Place each at the same depth or use ball valves to even out the air flow/ pressure.
