Which is The Best Pond Aerator? Buying Guide Inside

All pond water requires high oxygen levels in order to keep the water clean, maintain a healthy habitat for aquatic life, such as water gardens, and ensure that the pond water is not packed with unhealthy bacteria. Ensuring that you have the right pond aeration system for your pond is essential to making sure that you can enjoy the benefits of pond aeration. 

What To Consider When Purchasing A Pond Aeration System

Before browsing through aeration systems, it's important to determine what you want in an aeration system. Then, you can find the perfect product that will meet your needs. 

Access To Electricity

How close electricity is to your pond will determine the type of aeration system that you need as well as the cord length or tubing length that you need.

First, think about whether access is close enough for you to use an electric cord. If it is not, then you want a solar powered aerator.

If it is, take the time to measure the distance between the electrical outlet and your pond. This is going to tell you the length of the cord or tubing that you need. Some products come with a short electrical cord, but make up for this by offering a few thousand feet of tubing so that the tubing is long enough to reach the pond. 

Pond Size

Different aeration systems are designed to work for certain pond sizes. Air pumps with lower horsepower will not put enough oxygen into the water to properly aerate a large or deep pond. Tubing is often included in kits to reach the bottom of the pond, so you might not have the proper equipment to install your aeration system if you purchase one for the wrong pond size. 

To determine the size of your pond, you need to look at how many acres it is. Make sure that you know how many feet deep it is as well. It's also important to know how many gallons of water your pond is. To figure this out, you need to know how many acres your pond is. Then, use an online tool to convert acres into gallons.

The Type Of Aeration Needed

The two main types of aeration that pond owners need to know are surface aeration and subsurface aeration. 

Surface aeration systems oxygenate the top layer of water or the surface. For example, a water fountain that is designed for aeration. Some aeration systems come with tubing that is designed for floating on top of the water. These can be used in addition to subsurface aeration systems or by themselves. Pond owners with water gardens or shallow ponds often only need a surface aeration system.  

Subsurface aeration systems are also referred to as aeration diffusers. These systems have longer tubing included that will sink to the bottom of a pond. Oxygen is then diffused at the bottom of the pond where it circulates throughout the pond. These are exceptional at helping to remove algae, muck and providing plants and animals with oxygen. 


Pond aeration systems are available in every price range imaginable. Extensive solar powered systems can cost $10,000-$15,000. More affordable aeration systems designed for use with small water gardens may only cost a few hundred dollars. Settle on a budget before shopping for an aeration system. There is something available for every price range. 

Other Features That Are Needed

Pond aeration systems come with a variety of features. Some are quieter than others or include a soundproofing system. Solar powered systems occasionally come with backup solar batteries for days that the sun is not shining brightly. If you live in an area with harsh winters, you will need an aerator that helps de-ice your pond during the winter.

AirPro Diffused Aeration Systems

Diffused aeration systems from AirPro have air diffusers and sit on the bottom of the pond. This makes them ideal for a deep pond where fountains and surface aerators will not reach the bottom of a larger pond. 

The AirPro diffused systems have three components in each system. An air compressor sits on the bank. Then, it shoves air through a tube and out of an air diffuser that is in the pond. There are several benefits to these aeration systems. 

Various Sizes Available

A larger pond will need a larger aeration system to ensure that it has plenty of oxygen. Maintaining oxygen levels with an AirPro Pond Aerator that is too small is simply not possible. Thankfully, AirPro offers various sized products so that you can find whatever you are looking for regardless of your pond size. 

Long Tubing Systems Available

Top Of The Line Tubing

Pond fountains that are also designed to be aerators are ideal for increasing oxygen in surface water. The Kasco Surface Pond Aerator is one of the best on the market to keep your pond water fresh.

The tubing is long enough that equipment does not have to be close to water to ensure that it will not pose a danger for people or fish that enjoy using the pond as a swimming pond. 

Tubing Can Be Weighted With Any Substrate

While weighted tubes have their own list of benefits, so does tubing that does not come weighted down. You can use any type of substrate to weigh these down. They do not have to sit on the bottom of large sized ponds. Instead, the raised design helps oxygenate large sized ponds.

De-Icing Capabilities

One of the key benefits of pond aerators is their ability to help de-ice the top of a pond during the winter.  When a pond freezes over, it deprives fish and plants of critical sunlight and oxygen. Having a KLC Koi Pond Aerator will solve that problem all year long. 


While aerators are great for preventing a lack of oxygen, some of them are known for being noisy. that won't be a problem with this product. It's well known for being one of the quieter aerators on the market. You can enjoy relaxing beside your pond without being bothered.
