What is a pond aerator?

A pond aerator is used to increase the oxygen in the water. And do this without disturbing the fishes and plants in the pond.

It would work either by spraying water into a fountain on the surface of the pond. Or by pumping air into the water at the bottom of the pond.

It consists of a pump that is used to push the air through the pipes into a diffuser. And the diffuser is placed at the bottom of the pond to diffuse the oxygen into the water.

The benefit of using a pond aerator is that it keeps the water fresh. So you don’t face the problem of muck and algae forming in the pond. This avoids insects from breeding in the pond and prevents it from smelling.

What are the different types of pond aerator?

You can get a pond aerator that works on the surface or the bottom of the pond. And you could get those in a solar variant as well.

The solar powered pond aerator makes use of sunlight to run the pump. This means you don’t have any electric consumption as it’s free power from the sunlight.

However, these pumps need strong sunlight to work. So they’re suitable for the spring and summer seasons. And these solar-powered pumps are not as powerful.

Surface pond aerator

The surface pond aerator is placed on the surface of the pond and acts like a waterfall.

This type of aerator is suitable for small ponds with less fish and plants. They have the benefit of low power and less noise. And they don’t disturb the fish and the plants.

But the oxygen does not reach to the bottom of the pond. So it’s not suitable to prevent the growth of algae.

Diffusion pond aerator

The diffusion type of pond aerators are the most efficient to oxygenate the water.

The diffusers are placed at the bottom of the pond and release oxygen that rises to the top. This helps to pump oxygen evenly in the pond. And get rid of unwanted gases from the pond.

They make use of a compressor that in some cases does make noise when they’re large or high-capacity.

These types of aerator are suitable for all types of ponds from small to large. And they’re great at preventing the growth of algae in the pond.

Do you need a pond aerator?

The short answer is Yes, if you have a pond in your garden.

Every pond needs a good supply of oxygen to keep the plants and fishes in good condition. And to prevent the growth of algae, stagnant water, and insect breeding.

The plants and fish make use of the dissolved oxygen to survive. The bacteria and mcirobes that clean the water also make use of the oxygen.

Nature does this in large ponds with the methods of a waterfall or flowing water. But a man-made pond needs some help to get the required oxygen.

That’s why it’s beneficial to use a pond aerator to ensure the right amount of oxygen is present in your pond at all times.

The more the number of fish and plants in your pond the higher is the oxygenation it requires. The best way to know this is to observe the fish.

If they often come to the surface to gulp oxygen it could be a sign that your pond lacks a good amount of oxygen. Or the fish and plants could become lethargic and have slow movement and growth. Then you surely need to get yourself a pond aerator.

How to choose the best pond aerator

Durability

The compressor of the pond aerator will be on the ground while the diffuser will be inside the pond.

Both of these components should be durable so they last a long time. The compressor component should be able to withstand wind and the weather changes. And the diffuser and cables should be able to survive for a long time underwater.

Pond size

The type of pond aerator you pick should depend on the size of your pond. You should measure the capacity of the pond by the gallons of water it can hold.

You just need an estimate rather than an exact measurement of the capacity. And you should also figure out the depth of the pond. That’s because the pond aerator has a maximum depth to which it can work with efficiency.

Pond shape

The other factor that should influence your buying decision is the pond shape.

Round or oval shaped ponds are easy to aerate because the oxygen is evenly distributed. If the pond is irregular in shape, you may need the help of an expert to pick the right aerator.

Type

We’ve see the different types of pond aerator available to choose from.

If you’ve a small pond with a few fish and plants, a surface pond aerator can get the job done. It needs less power and makes less noise.

But you should remember that it’s not the most efficient at aeration. So you can’t use it to prevent algae growth in the pond.

The diffusion type of aerator is your best best when you want to prevent algae growth and get the best oxygenation. They should also be your choice when the pond is medium to large in size.

Do note that the larger the compressor the more noise they tend to make.

Output

The output of the pond aerator can be measured in the CFM (cubic feet per minute). This is the volume of air the pump pushes.

The higher the CFM the more powerful and efficient the pond aerator will be in diffusing oxygen into the pond.

Compressor

The compressor is the heart of the pond aerator that provides the power and efficiency. The stronger the compressor the more power it can generate.

If you have a large pond, you’ll need a pond aerator with a strong compressor.

The linear compressor is suitable for a small pond. And the rocking piston compressor is suitable for all types of ponds.

Price

The price of the pond aerator can vary based on the performance of the compressor and the technology used.

But you should pick one that is the most suitable for your pond and can give you performance for a long time. Often you get what you pay for. So remember that it’s OK if the price is a little high if you get the quality and performance.

Warranty

You can get the pond aerator that come with at least one-year warranty. The longer the warranty the better because you can use the aerator without worries about it breaking down.

Precautions when using a pond aerator

It’s quite simple to use a pond aerator and there’s not much precautions you need to take.

But do protect your compressor from the harsh elements and weather with the help of a cover.

Do make sure to use check values and put them in the right orientation. This will avoid water from flowing back into the supply lines when the aerator is turned off.

Run the pond aerator throughout the year because your pond needs a constant supply of oxygen especially during the summer months.

Every few months check the pond aerator that it’s working fine. If not you’ll need to perform maintenance as suggested below.

How to use a pond aerator

A pond aerator is a simple equipment that you should not have trouble setting up and using.

Unpack the aerator system and uncoil the tubing.

Fill the diffuser with material like gravel. This will help weigh it down and hold it underwater.

You need to install the pump on the surface in a dry area that is protected from the harsh elements and the weather. And it’s best to keep it near a source of power to plug it in.

Drop the diffuser in the deepest part of the pond and then turn on the aerator.

Check that the pond aerator is working as expected and diffusing oxygen into the pond.

Maintaining your pond aerator

It’s best to run the pond aerator throughout the year so it provides a constant supply of oxygen to your pond. This is crucial in the summer months where the heat will reduce the level of oxygen in the water.

Before starting the maintenance of the pond aerator, make sure to unplug it from the power.

Pull out the tubing and check there’s air coming out from the outlets. If not, you’ll need to fix the compressor or get it replaced.

Make sure the check values are in the proper orientation. This makes sure the water does not flow back into the pump.

Ensure there’s no kinks or obstructions in the air lines. Pull the aeration disks out and make sure there’s air coming from the air lines.

If the aeration disk has clogged, soak it in vinegar and clean it with a brush. If the disks are not working, you’ll need to get them replaced.
