Best Pond Aerator Buyers Guide

In our pond aerator buyers guide we'll discuss various aspects to help you decide if you need a pond aerator, and if so, what type and things to consider.

Now let's get into the details.

What is a Pond Aerator?

In order for water to become a suitable living space for plants, fish and other animals, it needs to be oxygenated. Aeration is the process that mixes that oxygen with water. Fish use the oxygen in the water to breathe and to help them process their food. The more waste there is in the water, the more nitrogen and phosphates there is to deal with.

Nitrogen and phosphates lead to aggressive blooms of algae and the death of your fish unless there is aeration to bring fresh oxygen into your water to build up the good bacteria. It also helps to keep bugs away.

Why Do You Need A Pond Aerator?

If you want your household pond to be as healthy as it can be, as well as a comfortable home for the fish in it, you need to make sure that your pond is aerated.

Not only will it make it healthier, but adding aeration will also make it easier to clean your pond in the long run.

You will still need to scoop up some pond scum and string algae off the surface, but you will have fewer algae in the long-term to deal with. This means less work for you in the long run.

Things to Consider Before Buying A Pond Aerator

- How big is my pond?

- What shape is my pond?

- How often are people looking at my pond?

- Do I have enough sun regularly to work with solar power?

- Do I need to have more than one type of pond aerator?

If you have a particularly large pond or an oddly shaped pond, you may need to have more than one type of pond aerator. You may want to combine a waterfall and a fountain, for example, if your pond is pear-shaped.

Power Sources for Pond Aerators


Electricity is the most common power source for pond aerators because it is the easiest to use. Once you have decided on what power configuration you need you will want to hire an electrician to install your new pond aerator.

Solar Power

If you live in a particularly sunny area, a solar panel may be able to produce enough power to power your pond aerator. This is more environmentally friendly and less expensive if you plan to keep your pond long term. It is, however, a front heavy outlay of funds and work to set up in the beginning.


Windmills and paddlewheels use the power of wind to power their functions, which is great if you live somewhere where there is a lot of wind. If you don’t, this might be more work than it’s worth.

Different Types of Pond Aerators


Waterfalls are perfect aerators for small, natural ponds where the water flows in one direction. They had great ambiance to your natural area and create a peaceful atmosphere around your water feature.


  • Pretty sound
  • Natural Look


  • Can be costly
  • Not efficient at aeration
  • Can leak and require maintenance on its own


Floating fountain aerators work best in shallow, symmetrically-shaped ponds. They offer a large, eye-catching centerpiece for your ponds. You can modify them to make them even more beautiful with LED lighting fixtures. These are common in golf course ponds. They pump water through a mechanism that propels it into the air, creating turbulence on the surface and mist from the spray.


  • Pretty
  • Efficient for Small Ponds
  • Mix of efficiency and natural looks


  • Not effective in deeper bodies of water
  • May require ongoing maintenance


Windmills make an impressive site for visitors to your pond and require no electricity. If you have a pond of medium depth, these might work well for you.


  • No need for electricity
  • Can work for shallow or deep ponds
  • Customizable
  • Can work to force air to both the top and bottom of the pond


  • Not useful when there isn’t wind
  • Hard to install
  • Can be ineffective on deeper ponds

Diffused Aerator:

Diffused aerators come in a variety of different packages and force air through tubes to the bottom of the pond. This creates very little surface movement but aerates the bottom layers of water.


  • Great for deep ponds
  • Do not disturb the surface


  • Requires electricity or solar power
  • It does not work well for shallow or small ponds

Frequently Asked Questions About Pond Aerators

How Can I Keep My Pond Clean?

The first thing you should do is to make sure that your pond is not overstocked. If you are adding koi or goldfish, be aware of the needed water to fish size ratio and remember that they will grow and possibly breed. Fish poop a lot, so make sure that you have a filter attached to your pond to help keep it clean. You should also avoid overfeeding the fish because the excess food will increase the likelihood of algae blooms within your pond and make it harder for your fish to survive.

The best thing you can do to keep your pond clean is to have a lot of living plants in it. Plants such as duckweed and lilies are easy to grow and can suck up many of the nutrients that algae would otherwise take hold of. You should also remove any dead plant material that you see, whether it’s leaves or extra seeds from other plants. This will help to keep your pond at the trade as free as possible

Should I add chemicals to my pond?

Chemicals are not entirely necessary for a healthy pond, but they are often helpful when something goes wrong with your water. I highly recommend keeping a set of water testing strips on hand to use regularly at the bare minimum.

Why don’t natural ponds need aerators?

In natural ponds, there are significantly more plants that use up nutrients within the pond and keep all of the nutrients at a balanced level that wards off the algae. Most man-made ponds do not have that amount of plant material to help create a healthy ecosystem, which creates the need for an aeration system.
