The Bubble Pro Sub-Surface Aerator - 1/4HP - 115V

By installing a sub-surface aeration system, you can improve the quality of water and increase oxygen levels in your pond while keeping its natural look. This type of aerator comprises two diffuser modules placed at the bottom of the pond, linked with weighted tubing that connects to an onshore air compressor.

During hot summer months, the compressor pumps essential air to the pond bottom to ensure adequate oxygen supply. The compressed air travels through the weighted airline and reaches the diffusers where numerous tiny bubbles are produced, creating an upward current when they ascend to the surface.

As a result, water from the pond's bottom rises to the surface where it interacts with the atmosphere, replenishing its oxygen content.

The Bubble Pro is manufactured in the USA



  • Two diffusers
  • Two lengths of 100-foot by 3/8-inch Quick Sink weighted tubing
  • 1/4-hp, rocking-piston compressor
  • Valved air outlet assembly with individual controls for each hose and a pressure relief valve
  • All required fittings and clamps.


Coverage Area

Acres Pond Depth
1/2 Acre 5' to 8' Depth
1 Acre 9' to 12' Depth
2 Acres 13' to 16' Depth

Designed for easy installation, the Bubble Pro comes with a two-year warranty. The Bubble Pro works as a pond de-icer too!

Safety Warnings:

• Use extreme caution when operating in winter. Danger due to thin ice can cause drowning. Unseen currents can cause thin ice in areas long distances away from diffuser operation. Provide adequate warning for others using a pond with a diffused aeration system.

• The surface of the compressor will be hot during operation. This is normal - be careful not to touch the compressor while it is running. • Units must be connected to GFCI protected outlets.

• Avoid using extension cords to operate compressor.

• Keep children or pets away from operating units • Always disconnect power when servicing system.

• Relieve pressure from system before servicing.



• All of our compressors are designed for continuous operation. It is not uncommon for compressors to run 24 hours per day for three to five years. The only maintenance required is replacement of wearable items (diaphragm, piston ring, vanes, etc.) when needed and keeping filter clean.

CAUTION: All compressors in these kits are designed for oil-free operation. Never oil or lubricate the compressors.

• In addition to adding oxygen to your pond, an aeration system creates a circulation action. It takes hours for the maximum effect to be achieved, therefore we recommend running these systems continuously so that maximum circulation is sustained.


Summer Time Start Up:

CAUTION: If you are installing this system at a time when your pond is already stratified (warm on surface, cold on bottom), you should be careful when first starting the aeration system. If the stagnant water on the pond bottom is stirred up too fast, a temporary increase in oxygen demand will occur and, in rare cases, a fish kill could result. If your pond is severely stratified, you should only run your system one to two hours the first day. Each day after that, increase the run time by one to two hours during the first week, run continuously after that. This will slowly mix the bottom water without a sudden depletion of oxygen.


Installation Precautions:

• The air diffuser should not be placed in the deepest part of the pond. Try to locate the diffuser at approximately 2/3 to 3/4 of the deepest point (a 15' deep pond would have the diffuser at approximately 10' to 12' deep). This allows the deepest water to remain cool in the summer and stay warm in the winter.

• If your pond freezes during the winter, be sure the tubing is buried leading into the pond. If not, the ice can form around the tubing, kinking it or possibly shearing it off. CAUTION: Locate all utilities before digging to ensure safety of installer and others.


Compressor Placement:

It is critical that the air compressors be protected from the weather. You will need to provide a shelter for your compressor to protect it from rain, snow and other harsh elements.

• Be sure your shelter is adequately ventilated.

• Be sure the compressor does not sit directly on the ground, as the vibration from the motor will cause dust and dirt particles to be pulled into the motor and may cause premature failure.

• If operating compressor in freezing climates do not place compressor in “heated” buildings. Warm air holds more moisture. This warm air may condensate and freeze in the colder outdoor line.

• Ensure that compressors are placed where they will not become flooded with water.

• If possible, shaded areas are preferred.

• In areas with limited electrical supply, compressors can be placed long distances from the pond edge. A remote access valve assembly can be fed from the compressor with properly sized tubing.


Diffuser Placement:

The amount of surface area an aeration system will effectively cover is greatly dependent on two factors - DEPTH and SHAPE.

The deeper an air diffuser is located, the more boiling action it will create and a larger area will be aerated.

The diagram below shows how much surface area is effectively aerated per air diffuser at various depths. Ponds that are irregular or odd shaped will also reduce size of aeration area - call us if you have any questions.



NOTE: The shape of a pond affects the amount of diffusers needed. Irregular shaped ponds often require multiple diffusers to adequately aerate entire water column.
