10 Best Pond Aerators in 2020 – (Reviews & Buying Guide)

Everyone knows the importance of using high-quality filters for your fish tanks. But, not many people know about how important an aerator is for a pond.

Pond aerators help to infuse oxygen into the water, which ensures fish have enough to survive.

Pond aerators come with a variety of different features. It is difficult to find the best pond aerators if you’ve never bought one before.

If you enjoy taking care of fish on a larger scale, this is an absolute must for you to include in their environment.

Why Use a Pond Aerator?

Unless you’ve taken care of fish in a pond before, you might not know why a pond aerator helps create a healthy aquarium.

In nature, ponds and lakes are aerated on their own with the movement of the water. Smaller, manmade ponds with no natural motion can benefit greatly from an aerator.

A pond aerator is useful for many things. Perhaps the most important is that it allows for increasing the oxygen levels in the water.

The aerator also helps to mix the oxygenated water from the top of the surface with the water at the bottom of the pond. This spreads oxygen but also keeps the water at the perfect hot/cold temperature for the fish.

Aeration also helps keep the water circulating, and it prevents pond muck from forming at the bottom. Not only does this muck smell awful and changes the color of the water, but it becomes a living space for leeches.

Aside from the muck, unaerated water is more susceptible to food pieces and other waste. This makes the water appear murky, and also increases the level of ammonia in the water.

Best Pond Aerator Reviews

1. Aquascape Pond Air Aeration Kit

The first aerator on the list is the Aquascape Aeration Kit. Aquascape designs effective and affordable aquarium equipment, so you can trust this brand.

This aeration kit comes with a pump that you place outside your pond. It has options for two or four outlets, too. You can adjust the amount you buy depending on how large or small your pond is.

The aeration discs are sturdy and made with a strong rubber covering, which protects them from any underwater scuffles.  The pump for this kit comes with a replaceable filter cartridge, too. This makes it easy to change and fix when it needs to be cleaned.

The only problem with the Aquascape aeration kit is that the discs it comes with aren’t weighted. So, they are not secure underwater.

They stay underwater for the most part, but they tend to move around easily. If these discs were held down by something, it would have been a more effective product.

Pros

• Easy to install
• Comes with different outlet options

Cons

• Discs aren’t weighted; move around underwater

2. Laguna Aeration Kit for Ponds

Next is the Laguna aeration kit for ponds. This aeration kit is another great option because of the value that you get for the cost of items. The Laguna aeration kit is most beneficial for use during the winter months.

Usually, ponds tend to freeze over and threaten the lives of the fish living in them. With this aeration kit, however, your pond can remain active even during winter.

The aeration system allows for circulation of the water with its 30-inch winter-safe tube lining. It continuously infuses oxygen into the water.

The downside to the Laguna aeration kit is that it definitely not a quiet one. This usually isn’t a problem for outdoor filters.

If you prefer to have peace and quiet by your pond, you might want to reconsider this option. This kit is fine on other points, but quietness is not a quality it has.

Pros

• Good value for the cost
• Excellent for year-round use
• Comes with ample tubing

Cons

• Not a quiet aeration system

3. Aquascape Pro Air Pond Aerator and Aeration Kit

Moving on to the next product, there’s the Aquascape Pro Air Pond Aerator and Aeration Kit. This is another great product by Aquascape, which is definitely a good place to turn to if you’re confused about which aeration kit to buy.

This kit comes with a hardworking 15-watt compressor that’s both weather-proof and perfect for the outdoors. That means more peace of mind for you even if the weather isn’t so great.

There’s also a 30-foot roll of tubing that comes in this kit. This makes it very easy for you to aerate the whole of your large pond for up to 5,000 gallons (15,000 gallons with PRO 60).

It’s a great kit all around and is a good investment to make if you’re serious about pond aquariums.

One thing that’s a strike against this aeration kit is the price. This kit comes with a lot of high-quality and well-designed items.

While it’s true that you definitely get what you pay for, the price of this kit is still a bit higher than others. The quality is definitely there, but it might not make everyone’s wallet happy.

Pros

• Weather proof
• Energy Efficient

Cons

• High price for the quality of items included

4. Air Pro Deluxe Pond Aerator Kit

Now, if you’re looking to aerate a very large pond, you need something with the power that can handle that task. That’s where the AirPro pond aerator kit comes in. This tiny aerator is capable of infusing oxygen into a pond the size of an acre of land!

It’s very powerful, and it can operate efficiently when it’s underwater for up to 50 feet of depth. This aerator is a heavy-duty tool, and it built to last through many years with its design and warranty.

A problem that a few people might have with the AirPro pond aerator kit is the price. It’s important to understand that this isn’t just an average aerator. Because it’s meant for very large and deep ponds, it’s definitely going to cost a lot more than a regular aerator.

Objectively though, it’s still a lot more expensive than the other products on this list. If you’re looking for an aerator that’s easy on your wallet, look past this one.

Pros

• High-quality products
• Very powerful system that aerates up to an acre of water
• Great warranty

Cons

• Expensive compared to other aerator kits

5. EasyPro PA6SWN Single Diffuser Shallow Pond Aeration Kit

Another great heavy-duty option for pond aeration kits is the one designed by EasyPro. This kit works perfectly for ponds that start at seven feet in depth all the way up to 3/8 of an acre of depth. That means it can handle almost all pond sizes, deep or not.

It comes with a DM4 diffuser and 50 feet of tubing. The good thing about the tubing is that it’s designed to be quick-sinking.

This means you don’t have to worry about it floating around your pond all the time. It’s also designed to be used during all types of weather and has the extra protection of the pump for this reason.

The problem with the EasyPro Diffuser Aeration kit is that it’s a bit expensive for what’s included.

There are other kits on the market that do similar things and come with similar features. However, they are less expensive than this one. With a little bit of research, you could probably find a similar model for a smaller cost.

Pros

• Great diffuser model
• Quick sinking tubing

Cons

• Expensive compared to other models with similar offerings

6. Danner 04560 Pond Aeration Pump with Diffuser

Danner’s aeration pump with diffuser provides high airflow with quiet operation, delivering all the benefits of aerating your pond without adding distracting and unnecessary noise. This model is energy efficient and the six-foot cord makes placement and setup easy.

When it comes to aerators, the closer you place them to the bottom of the pond, the better. This model is powerful enough for ponds up to 7,000 gallons. The oil-free motor is energy efficient and uses an air manifold that’s compatible with 0.75-inch diameter tubing.

This aeration pump is meant for large ponds with a maximum water depth of 10 feet and circulates about 5500 cu in/min. Note that it requires ¾-inch tubing which is not included. There are less powerful models available for smaller ponds, too.

Pros

• This aerator provides high airflow with quiet operation
• Placement and setup are easy thanks to the six-foot cord
• It’s easy to extend the reach of the aerator because the manifold is compatible with 0.75-inch diameter tubing
• You can use this pump in large ponds up to 10 feet deep and 7,700 gallons

Cons

• It can be difficult to find replacement parts
• The necessary ¾-inch tubing is not included

7. Blue Diamond ET 80 Septic or Pond Linear Diaphragm Air Pump

One of the best things about this aerator from Blue Diamond is the aluminum chassis which makes it really durable. Because it has no wearing parts, it’s weatherproof and capable of running intermittently of continuously.

The quiet, oil-free operation is ideal for ponds because there’s no excessive noise to distract you or bother your fish. If you ever need to make a repair, affordable spare parts kits are available and generally easy to find.

This air pump has a 75 liter/minute flow which is appropriate for up to 500 gallons and water up to six feet deep. It’s covered by a two-year warranty. Blue Diamond typically has good customer service, too, so if you have any questions or problems, feel free to get in touch.

Pros

• This pump has a durable aluminum chassis that’s built to last
• It’s capable of running continuously because it has no wearing parts and operates oil-free
• Spare parts are affordable and easy to find

Cons

• Some people thought it was a little loud, though this wasn’t common

8. Airmax CrystalClear PondAir Aeration Kits

This aeration kit from Airmax is perfect for anyone just starting out or setting up a new pond. It’s extremely quiet and circulates up to 0.3 cu ft/min, the ideal size for a pond that’s about 2,000 gallons and two feet deep.

Because this is a kit, there are a lot of things included. You get four 2-inch airstones, four 30-feet rolls of tubing, and four check valves. The airstones create ultra-fine bubbles that increase the rate of oxygen absorption and you can place them wherever you want.

One of the best things about this pump is that it’s extremely energy efficient. You can dial-in the power to four to eight watts and it costs as little as 40 cents a month to run. There’s a smaller option available, too, that works in ponds up to 1,000 gallons and includes two airstones.

Pros

• This kit includes the pump itself four airstones, a total of 120 feet of airline, and four check valves
• You can use this pump in small ponds up to 2,000 gallons and two feet deep
• It’s energy-efficient and costs as little as 40 cents a month to operate

Cons

• Airmax recommends keeping the pump covered from direct sunlight which may be difficult to do in an outdoor pond

9. Hi-Blow Linear Air Pump Pond Aeration Septic Aerator

Nearing the end of the list is the Hi-Blow Septic aerator. This is another great product that’s well-designed and has great customer reviews.

It can easily infuse up to 80 liters of air into the water per minute. This gives it great reviews when compared to other aeration pumps on the market.

It has a 71-watt power system, is sturdy, and can last for several years before needing a replacement. A cool feature it has is an alarm connection fitting.

The problem with this aeration kit is that it has very few extra features included in it. You just get the aeration filter and some tubing, but other than that, nothing.

You can find many different products with more tubing, for example at a better price. If you want an aeration pump, this is a good option for you. If you’re looking for an actual kit, you should try something else.

Pros

• Sturdily built
• High power, but still very safe to use
• Alarm connection fitting

Cons

• Not many extra features

10. Airmax KoiAir Water Garden Aeration Kit

The last product on the list is the Airmax KoiAir aeration kit. It is best for medium to large-sized ponds, and this aerator can circulate oxygen into up to 8,000 gallons of water.

This kit is beneficial in reducing the muck in these large ponds. It also helps to create clearer water, whether it’s deep or not.

This aerator has an energy-efficient 17-watt compressor and a diffuser plate. It also comes with two diffuser sticks. There’s also a six-foot energy cord for easy access to an outlet.

There is one big issue related to the Airmax KoiAir aeration kit. Even though it’s marketed as being a weighted product, it still doesn’t disappear into the water as it should.

There are some instances when the product just doesn’t go down, or if it does, it’s not low enough. This can affect how well it works, so it’s definitely something to be wary of.

Pros

• Good for medium-sized ponds
• Energy-efficient design

Cons

• Equipment is not well weighted

How to Choose a Pond Aerator?

Now you have a good idea of the different features and costs of pond aerators. So, it’s time to find the one that’s best for your needs, specifically for your fish’s needs. It’s easy to figure out which option is right.

From all of the great pond aerators out there, choosing just one seems like a daunting task. But if you remember a few key details about your pond, the search for the perfect aerator gets a lot easier.

Size of the Pond

The size of your pond is the first thing you should look at before deciding which aerator you should get. Measure or have a professional measure the amount of water in the pond area in gallons.

If it’s a very large body of water, you might have to measure it in acres. It won’t be an exact measurement in most cases, but even an estimated size is helpful in finding your aerator pump.

Pond Size Calculator

Depth of Pond

The depth of your pond also plays a big part in getting an aerator for it. Some aerators have a maximum depth point that they can effectively work. Make sure to keep that in mind.

If they go below that, there’s no guarantee that your water is getting properly aerated. Measuring the depth of your pond can also help you find a matching aerator for the job.

Pond Shape

This may be surprising, but even the shape of your pond affects the types of aerators that you should buy. Circle or round ponds can easily be aerated by any type of diffusion system. This is because the oxygen can be easily distributed around the pond.

Ponds with irregular shapes or depths can get tricky to cover, as the area is not all one depth. Speaking to an aeration service provider can help you with this problem if you’re unsure.

Types of Pond Aerators

You need to learn about the types of pond aerators before buying one for your pond. There are a few different types. The main ones are either submersible or floating fountain aerators.

A submerged aeration system releases oxygen directly into the water. This system works well for irregularly shaped ponds.

Floating fountain aerators usually float in the middle of the pond. They provide aeration through a falling water fountain feature. These work better for more regularly shaped ponds, like circular or triangular.

Compressors

The compressor on the aerator affects how well the aeration process goes. Two very common compressors are the linear compressor and the rocking piston compressor.

The linear compressor uses an internal diaphragm to create and release air. This is perfect for smaller ponds.

On the other hand, the rocking piston compressors are great for any situation. Both shallow and deep ponds can benefit from this type of compressor.

Where to Place Pond Aerators?

Once you find the right type of aerator, you need to place it in an area of your pond where it can be the most effective. This is typically the deepest area of your pond. Why?

Because it is where the most muck is and the least amount of circulation is. Alternatively, you can ask an aeration service technician to advise you on where to place it.

How to Install a Pond Aerator?

Installing a pond aerator is a quick and easy process. You might be surprised how easy, in fact.

First, remove the aerator from its packaging and uncoil the tubing.

Next, fill the diffuser and weigh it down with gravel or something else to hold it down underwater. You should also set up your pump on dry land. This ensures that it’s well protected from the elements and has ample access to an energy source.

Sink the diffuser into the deepest part of the pond, then turn on your aerator. If all went well, your aerator should be up and running smoothly! It couldn’t be simpler.

When to Run Pond Aerator?

Ideally, you should be running your pond aerator year-round, but especially so in the summer months. During the summer, the heat of the water lessens the dissolved oxygen in it.

There’s also a higher level of decomposition happening in the water in the summer. This means less oxygen for your fish. You should take care to aerate regularly to preserve your pond and keep your fish healthy.

Conclusion

After all of that information, you should feel a bit better about buying an aerator for your pond. It seems like a lot of research is involved. Because of that, many people skip aerating their ponds altogether.

As a pet owner and pond enthusiast, pay special attention to the environment you create for your fish. You want to ensure they have a healthy life, and aerators are the perfect tool to make this a reality. If you need more help, feel free to reach out to a pro. They can offer even more advice on which kit is best for your needs.
