What is a Pond Aerator?

Aerators for ponds are a great way to introduce more air into the water. They move water around and refresh the stagnant water to keep it oxygenated. As an added benefit, this process usually adds appealing visuals to the pond, which is why you’ll often see them used in neighborhoods and other public places.

Ponds with proper aeration provide a health environment for the animals living in the water. So, if you’re in charge of a pond that has fish in it, you can greatly benefit from a pond aerator.

Do You Need a Pond Aerator?

You don’t need to aerate your pond, but the positives greatly outweigh the negatives. If you’re looking to create a healthy environment for your fish, adding an aerator is a great way to do it. Yet, like all equipment, it takes extra time and money to set up.

So, let’s look at the pros and cons of these products to help you decide if you should invest in one.


  • It provides oxygen in the pond
  • The fish in the pond will be healthier
  • It makes the water clearer.
  • Most options look visually appealing
  • It can decrease mosquito activity


  • It can be expensive
  • It may be difficult to find the right one for your pond

Types of Pond Aerator Systems

There’s a variety of pond aerators to choose from, but the options usually boil down to two types: fountain and diffused aerators. So, let’s take a look at the differences.

Types of Pond Aerator Systems

Fountain Aerator

Fountain aerators usually refer to aerators that float on the pond and shoot water upward. The water molecules attach themselves to air to bring oxygen into the water when they fall. These aerators are primarily used for decoration, but they do provide a good amount of aeration to a certain depth.

However, if you have a pond that’s deeper than six feet, the oxygen might not reach the bottom half of the water. If that’s the case, you’ll want to consider a diffused aerator for a pond instead.

Diffused Pond Aerator

Diffused pond aerators release air bubbles from the bottom of the pond rather than the surface. These aerators are usually places within two feet of the deepest part of the pond. With this product, tiny air bubbles will be released, and they’ll dissipate throughout the pond.

The best pond aerators are usually diffused products because they cost less while being more efficient. If the appearance of the product isn’t important to you or if you have a deep pond, a diffused aerator will be more practical than a pond aerator fountain.

Setting up Pond Aeration Systems

How you set up a pond aerator depends on the specific product you choose. Most pond aerators will come with instructions for how to do it. If you’re worried about having an aerator that plugs in, there are plenty of solar pond aerator options to choose from. A windmill pond aerator is another alternative.

The most important part of installing an aerator is finding the most efficient place to put it. However, if you’re struggling to get the product to operate, you can always call a professional to install it for you.

Setting up Pond Aeration Systems

Consider Your Pond Size

To choose the right product, you’ll need to think about the size, shape, and depth of your pond. Most aerators say how many gallons and how deep the pond should be for the best efficiency. If your pond is more than six feet deep, you’ll want to choose an aerator that goes underwater instead of using a floating fountain.

If the pond is round, you can get away with only having one aerator toward the center. However, ponds with irregular shapes can have dead zones that don’t get enough oxygen. So, choosing a product with multiple outlets can help the oxygen spread further. You can also buy more than one aerator in that instance, but it’s not as convenient.

Where to Put it

As mentioned earlier, the outlets work best if placed close to the deepest spot of the pond. However, the aerator itself should be on land within 1,000 feet of the pond. It should be away from where people usually walk and close to a power source if needed.

The location of the aerator’s parts may vary based on what your pond looks like. If it doesn’t seem to be working efficiently, you may need to make some adjustments to improve the quality of the water.

Best Fish for an Outdoor Pond

If you’re setting up an outdoor pond, you’ll need to choose fish that are suitable for that environment. Here are a few species to consider:

  • Koi
  • Goldfish
  • Loach
  • Fathead minnow
  • Hi-fin Shark

These are just a few popular options, but before choosing one, make sure you research the breed and ensure that you can supply suitable water conditions.

If you want to have more than one species in your pond, make sure they have similar temperaments and care requirements. Otherwise, one might thrive while the others get sick. It’s easy to get distracted by the beauty of fish, but their health and well-being should always come first.

Frequently Asked Questions

Setting up a pond aerator can be a lot of work, so it’s a good idea to get all your questions answered first. Here are a few things people commonly wonder before buying one.

Outdoor Pond
What’s the Difference Between a Floating Fountain and an Aerator?

Technically, a floating fountain is a type of aerator, but it aerates the pond at a much lower rate. Floating fountains have a pump that forces water upwards to look appealing. So, efficiency and quality aren’t prioritized as much as appearance. However, it’s still a better option than no aerator.

Does Rain Add Oxygen to a Pond?

Yes, heavy rain is a natural form or aeration. Like a waterfall, it helps move the oxygen around in the water to keep it healthy for fish. Yet, rain isn’t as consistent and predictable as an aerator product, which is why it’s still a good idea to purchase one.

Do Aerators Attract Fish?

Yes, aerators are appealing to many fish. The fish in your pond might become curious and want to swim near the bubbles. So, it can be a bit of entertainment for them while also keeping them healthy. However, some fish are more skittish than others, so if that’s the case, choose an aerator that’s quiet.

Finding the Perfect Pond Aeration

If you’re looking to raise fish in an outdoor pond, such as a koi pond, you’ll need to think about getting aeration systems for ponds. Fish can survive without an aerator, but aerating a pond can also make them much healthier. The pond plants you use will also thrive with proper aeration. So, aerators have way more benefits than downsides.

Consider the size, shape, and depth of your pond when choosing the right product. Luckily, there are plenty of options out there that are both visually appealing and efficient.
