How to Select an Aerator?

With different kinds of ponds, there are different types of pond aerators to keep your water clean, and the plants and animals living in it healthy.

Pond Size: The size of your pond will help determine the size of your pond aerator. The bigger the pond, the bigger and more powerful aerator you will need, along with multiple valves included. Also, the bigger your pond is, it’s more likely you will need an aerator able to operate 24/7.

Pond Depth: The deeper your pond is, the more powerful of an aerator you will need. More power can be found in higher voltage, which will essentially use more energy. The more powerful aerator is needed to prevent pond separation in dry times. The shallower your pond is, the more likely you will need an aerator with anti-ice features, able to operate in the winter.

Energy Usage: The bigger your pond is, the bigger and more powerful your aerator will need to be, and the more energy it is going to use. If you want your aerator to operate 24/7, that will use more energy than, for example, a nine hour shift.

Noise Level: With more power typically comes more noise, but that isn’t always the case. Some aerators, if fully submerged in the water, will be very quiet, and if not fully submerged, will make vibrating noises. Some aerators are louder than others. Noise level usually depends on the quality of the material the aerator is made of, along with its power.

Durability: Typically, plastic aerators are not going to last as long as more weatherproof aerators, made out of steel, or other durable materials. With durability usually comes quality, so if you purchase a durable aerator, expect it to work well and long.

Advantages of Having a Pond Aerator

Without a pond aerator, your pond may not have enough oxygen, or have too much algae. Getting an aerator can help regulate your pond. Here are some advantages to adding one toy our water.

  • Oxygenating your pond will provide for any animals or plants living in the water and allow them a healthier life.
  • If you have a lot of algae in your pond, some aerators have been known to completely clear the water in as little as three or four days.
  • Having an aerator creates a more stable environment, and are a very energy efficient way to do so. Many aerators come including all required parts.
  • If you’ve noticed an unpleasant odor around your pond, it is likely because of an unstable environment; a pond aerator cleans your water, and cleans your air of those odors.
  • With the clean water from your aerator, the area around your pond will actually become less popular with mosquitoes, because there won’t be as much for them to feed on. This will provide a much more fun atmosphere for you.
  • Without an aerator, your pond could accumulate sediment at the bottom. An aerator helps keep the water moving by creating bubbles, and this will decrease the amount of sediments settling on the bottom.
  • Along with keeping the fish and plants in your pond healthy, pond aerators also reduce bacteria in the water. Overall, this makes your pond a much safer area for everybody.

How a Pond Aerator Works

Although there are many different models and forms of pond aerators, essentially, they all have the same standard operational systems.

First, all pond aerators typically need the same equipment. They all need the actual aerator itself, an air compressor, and hose tubing to carry the air.

All aerators are typically not battery-powered. This means that they also need a power cord. Some come equipped with a six foot power cord, and some include much longer power cords. Either way, they will often need extension cords, with tubing to ensure that they are weatherproof.

All aerators come with different voltage and energy usage, but the higher the voltage, the more powerful the aerator. The more powerful the aerator, the bigger the pond it can be used for. More power in an aerator means that it can pump more water, measured in gallons per hour.

Some aerators even come with attached fountain heads. Although regularly made for smaller ponds, the addition of the fountain adds to its effectiveness. Water coming from the fountain helps the aerator mix the elements within.

Simply put, pond aerators provide the water with more oxygen, as well as mixing the water up. Missing the water up is done by releasing bubbles into the water, which also provide oxygen. The higher quality of the aerator, the finer the bubbles will be.

Frequently Asked Questions about Pond Aerators 

How can I protect the pump when exposed to the elements?

Some pumps are weatherproof, but many are not. So, many brands suggest keeping it covered with anything that will protect your air pump from the elements. It is also recommended to keep the aerator from having direct contact with the ground. This can be done either decoratively or effectively.

How many gallons of water can this pump serve?

All pond aerators differ in the amount of water they are capable of pumping. Measured in gallons per hour, the more powerful the aerator, the more water it will be able to pump into your pond.

Is it okay to add pebbles or river rocks to my pond?

It is highly recommended to not add pebbles, rocks, or stones to the bottom of your pond with an aerator. Having these on the bottom of your pond makes it very difficult for the aerator to thoroughly clean it. Although it may look good now, in the end, it will make things much more difficult.

How much power does this use/require?

The amount of power your pond aerator uses depends on a few things. First, how often you have it running. If you have your aerator running 24/7, 365 days a year, it will use more energy than if just for half a day. Also, the bigger and more powerful the aerator, the more energy it will require.


Overall, pond aerators are important to the entire atmosphere around the water. They keep the water clean, allowing for healthy fish and plants, along with keeping bacteria away.

There are many different forms and models of aerators. Different sizes and different powerfulness per pump ensure that finding the right one for your pond is incredibly doable.
