How Does a Saltwater System Work?

If you’ve been dreaming about pool season, you’ve probably come across the term saltwater pool more than once. Maybe your neighbor won’t stop raving about theirs. Maybe you saw it mentioned in a home reno show. Or maybe you’re tired of the harsh chlorine smell that sticks to your skin after a swim. Whatever the case, saltwater pools are becoming more popular—and for good reason.

So, what’s all the hype about? Is it really like swimming in the ocean? (Spoiler alert: not quite.) Let’s break it down.

How Does a Saltwater Pool Actually Work?

Despite the name, a saltwater pool isn’t filled with ocean water. It’s not going to sting your eyes or taste like a margarita (sorry.) The salt content is actually very low—about 1/10th the salt of seawater. In fact, most swimmers can’t even taste it.

The magic happens in a device called a salt chlorine generator or just a salt cell. Here’s the idea:

• You add pool-grade salt, usually sodium chloride, to water.
• The salt dissolves, and the water passes through the generator.
• Inside the generator, an electrical reaction splits the salt molecules, producing chlorine.
• That chlorine sanitizes the pool water, killing bacteria, algae, and other unwanted guests.
• The chlorine eventually breaks back down into salt, and the cycle starts over.

If this sounds pretty cool, it is. You get all the sanitation benefits of chlorine without having to manually dump chemicals every week. It’s like your pool becomes a self-cleaning system.

Why People Love Saltwater Pools

So, why are more and more pool owners switching to a saltwater system?

Softer on Skin and Eyes

One of the biggest complaints about traditional chlorine pools is that they leave your skin dry and itchy, and your eyes red and burning. Saltwater pools? Not so much. The lower chlorine levels and steady output from the salt cell mean gentler water. Many people with sensitive skin or parents with kids who swim for hours swear by it.

Way Less Maintenance

Ask any pool owner, and they’ll tell you how much they hate constantly adding chemicals, adjusting pH, and trying not to feel like a mad scientist in the process. Saltwater pools still need regular testing, but the system regulates itself much better. Once the salt is in and the generator is set up, you don’t have to micromanage your water chemistry as much, and that’s one less thing on your to-do list.

No Harsh Chlorine Smell

That sharp chlorine smell we associate with pools? That’s typically caused by chloramines—byproducts from when chlorine reacts with body oils, sweat, and other stuff. Because saltwater pools generate chlorine in smaller, more consistent amounts, you don’t get that overpowering odor. In fact, most saltwater pools smell pretty neutral.

Saves Money in the Long Run

Yes, saltwater pools have a higher installation cost upfront, especially if you’re retrofitting an existing pool. But over time, you spend less on chlorine and other chemicals. And because the water is more stable, your equipment tends to last longer. Many pool owners find they actually save money over the years.

And let’s not forget the time savings. Not having to constantly test the water and add chemicals leaves you with time to do more important things—or nothing at all.

Keep in Mind

No system is perfect, and saltwater pools do come with a few caveats:

• The salt cell will eventually need to be replaced, generally about every 3-7 years.
• Saltwater can be a little tough on some pool materials, like metals and natural stone, if not properly sealed.
• You still need to monitor pH, alkalinity, and calcium hardness.

But for most people, the benefits far outweigh the upkeep.
