What Is a Pool Aerator?

If you’re anything like us, the pool is where you go to beat the summer heat and cool down when the temperatures soar. But proper aeration is essential for a comfortable swimming experience, especially in hot climates like Florida. A pool aerator could be the device your system needs to maintain a cooler water temperature. Today, we’re diving into the functions and benefits of pool aerators to help you decide if these accessories are right for you. 

What is a pool aerator?

A pool aerator is a small device that cools your pool water using existing pressure from your pump. Here’s what you need to know about these systems: 

How does a pool aerator work?

Pool aerators are inexpensive devices that connect to a return jet on in-ground pools and spray a fine mist of water into the air where it’s exposed to fresh oxygen, cooling it down before it returns to the pool. In most cases, you can simply turn on your aerator valve to kickstart the process. While most aerators are powered by your pool’s pump, others rely on solar panels to operate.

What is a pool aerator used for?

Temperature regulation is the main function of a pool aerator. These devices may lower water temperatures by 3 to 4 degrees Fahrenheit, especially at night when the air is cooler. They also increase oxygen levels, improve circulation by increasing surface movement, and raise pH levels. 

Pool aerator vs pool filter

Both pool aerators and filters facilitate the flow of water, but that’s where the similarities end. An aerator is an optional accessory that reduces temperatures and improves circulation, while a filter is an essential component that removes dirt, debris, and other contaminants from your pool.

Benefits of a pool aerator

Let’s dive into all the benefits a pool aerator can offer, from more comfortable water temperatures to enhanced circulation. 

Cools down pool water

Most people install pool aerators to maintain cooler temperatures when the weather is hot. These pieces of equipment have nozzles that spray water into the air, breaking it into smaller pieces with greater surface area.

At this point, evaporative cooling takes effect, and the water temperature quickly drops before returning to the pool. You can further maximize this process by running your pool aerator at night.

Improves water circulation

A pool aerator won’t replace your pump, but it can enhance circulation and prevent stagnant water. These devices can be particularly beneficial for preventing dead zones near corners or steps, and improve the functionality of ozone generators.

Raises pH levels

Acidic pool water can corrode stainless steel equipment, etch plaster, and irritate skin and eyes. If you’ve added muriatic acid to your pool to combat cloudy water or scaling, you may need to raise the pH without affecting the water’s alkalinity.

This is where a pool aerator can come to the rescue. An aerator increases carbon dioxide exchange at the surface, naturally facilitating this process.

Is a pool aerator worth it?

An aerator can be a great addition to your pool, especially if you live in a hot climate. Here are a few factors to keep in mind: 

Consider the cost

You can purchase a simple, screw-on pool aerator that connects to a return jet for about $20. These inexpensive options can support more comfortable temperatures and improve circulation on just about any budget. If you’d rather go big, you can opt for built-in aerators or decorative models that function as fountains or waterfalls.

Review different types of pool aerators

The right pool aerator depends on the type of pool you have and your aesthetic goals. Basic screw-on jet aerators are suitable for above- and in-ground pools, and are great for folks on a budget. Deck jets and laminar jets are built-in accessories often added to luxury spa pools.

Wall-mounted sprayers are a good balance between economical and high-end models. And then you have floating and return-mounted fountains that blend form and function for pool owners who want to enhance the ambiance in their backyard.

Think about maintenance needs

While pool aerators are naturally low-maintenance, they can get clogged with calcium and other debris. A soak in vinegar or a descaling solution is usually enough to resolve this issue.

Cheaper options may need to be replaced every few years due to general wear and tear. And, folks in freezing climates will need to winterize their aerators along with the rest of their swimming pool systems each winter.
