Pond Aeration Information

  • Is your pond 6ft. in depth or deeper?
  • Have you seen your fish gasping for oxygen at the top of your pond?
  • Are you having unsightly algae problems in your pond?
  • Does your pond appear to be stagnate and lifeless?

The Benefits of Pond Aeration  

If you have answered yes to any of the above questions or want to improve your water quality -- read this info!


    "Aeration" is the term that we use to mean adding air to the water.

Because air contains 22% oxygen aeration adds oxygen to the water.


If you have answered yes to any of the questions above your problem may be due to insufficient levels of oxygen in your pond.

Ponds that are deeper than 6 ft. simply are not capable of producing significant levels of oxygen at those depths. Below is an illustration that will show you the problem:

pond without aeration lacks oxygen

The good health of a pond is held in a delicate balance. A pond's condition deteriorates when its bottom environment cannot support animal life. The bottom is the area that runs out of oxygen first (the bottom is where the most oxygen is used and is the farthest from the surface where it is replenished). The absence of oxygen kills all of the bottom dwelling animals that help keep a pond clean. The loss of these animals (snails, mussels, worms, etc.) will greatly reduce the pond's ability to clean itself.

 Nutrients (fish waste, grass clippings, dead algae, etc.) cause most water quality problems. Nutrients are cleaned from a pond's bottom by the small bottom dwelling animals mentioned above. When these animals do not exist the nutrients accumulate on the bottom forming a layer of "muck" which serves as fertilizer for weeds and algae. If a pond is allowed to get seriously infested with weeds, herbicide treatment may be the only way to gain control. The idea is to prevent such infestation in the first place. Natural water cleanup through aeration offers preventative maintenance, reducing sediment before more serious problems arise.

    Pond Aeration - By pumping compressed air out into a pond or lake bed aerator -- an air diffuser that produces tiny air bubbles -- the rising air bubbles bring bottom water to the surface where it is exposed to the atmosphere. Large volumes of water thus lose bad gasses to the atmosphere and the water picks up even more oxygen while on the surface

   Surface Splashers Vs. Diffused Pond Aeration

    Surface Splashers include but are not limited to the following:

    -Look at the illustration below and notice how a diffuser will saturate the entire pond with oxygen and not just the surface. Unfortunately, as you can see the surface units expose just surface water to the atmosphere. NOT deep water.

  • Fountains are a popular choice when a decorative aerator is desired. Fountains splash the surface of the pond and help control surface algae and duckweed, but do not aerate down to the bottom in deep ponds.
  • Diffused pond aeration is the best way to aerate deep ponds. Because the air diffuser lays on the bottom you achieve total pond aeration from top to bottom regardless of depth.

Diffused aeration systems are the best way to aerate, destratify and create circulation on ponds over 6' deep. Each system has three basic parts:

        1.  Air compressor

        2. Air hose

        3. Air diffuser

         The air compressor sits on shore and pumps air out through the hose to the air diffuser located on the bottom of the pond. The result is thousands of tiny bubbles rushing out of the diffuser to the pond surface, creating circulation and providing aeration. There are several advantages to using diffused pond aeration kits instead of surface aerator:

        1. Electric motor is on shore, not in the water; 

        2. Air diffusers lay on the bottom, ensuring aeration of entire pond from bottom to top, regardless of depth size;

        3. With proper sizing, tubing lengths up to 2000' can be achieved for ponds without electricity nearby.

    -Oxygen is most needed at the bottom or deepest part of a pond.

    -Surface Splashers can also be a safety hazard, electric wires need to be ran from your power source out to the motors in the water

   Please Note: We do recommend Surface Splashers for ponds that have
a maximum depth of 5' or less. Diffused Aerators are not recommended in shallow water.

    How do I know that I am purchasing the right size unit for my pond?

The deeper an air diffuser is located, the more boiling action it will create and a larger area will be aerated. Therefore the deeper your pond the less CFM needed to aerate your pond. 1.5 CFM of air can effectively aerate a 1 Acre pond at a depth of 12' or deeper. The chart below can be used to determine the size of the compressor that you will need, it is based on a compressor producing 1.5 CFM of air.

Our Pond is close to a rectangle shape with the long about 175 ft and the short ends, one about 65 ft and the other 100 ft. Most of the pond is 2-3 ft deep with the deepest part in the middle to the dam end being 4- 4.5 ft deep. We have a lot of hydrilla and coon tail in the pond which we have treated and killed out almost all of it. The pond is about 250 ft from the nearest power. I wondered what aeration system you would recommend? Thanks, Denise in South Carolina

Because your maximum depth is only 4.5 feet you will definitely want to consider surface aeration. We have surface aerators that come in 115v and 230v. I would need to know what kind of power you have available because the 115v have a max cord length of 200' and the 230' you can go up to 400'. If you have 230v available I recommend this aerator: http://www.livingwateraeration.com/af3400h.html You may need to contact your electrician to see if this would be an option for you. He might even be able to bring a junction closer to your pond and you could then opt for the 115v.

how many hours per day must I run aerator
1 Answers
Our optimum recommendation is 24 hours per day, year round. However we do understand some people are on a budget and want to conserve electricity in that case we would recommend a timer 12 hours on and 12 hours off. But if you can run it all the time that is the best option.

from maine asked:
May 28, 2017
i was wondering if you could help me out. I have been getting so many different answers from so many different people that i have no idea what is right or wrong. I have a 1/4 acre pong approximately 100 ft x 50 ft and is is 18 foot on one side and gradually get shallower on the other side where it is about 6 ft deep. Now the question is how much aeration do i need? how big of a system do i need? I have some saying that do to the depth i would need something pushing out over 3.5 cfm with at least 2 diffusers. I see others saying that system would be too big. i was told not to do solar cause the systems wouldnt be ablt to handle the depth due to only pushing out 1.1 CFM. (looking at solar cause the electric run form the house is 100 ft. SO i am completely confused and am not sure what to get. i want to buy the right system and not waste my time or money on things i dont need. i have had people telling me that i need over 250 feet of the hose which seems really excessive but when you dont know what you are doing you can get taken advantage of. i just want a truthful honest answer for what type of system would be suited for my application without trying to up sell me or sell me **** i dont need.

We recommend this unit for your pond size if you go electric: http://www.livingwateraeration.com/pa33w.html Or if you go solar then we recommend this one: http://www.livingwateraeration.com/soaenobaba.html There is no way you need more than that for a 1/4 acre 18 foot deep. You have depth as your advantage because the deeper you can place your diffuser the more surface area you can aerate effectively.
