🧂 The Truth About Saltwater Pools: Pros, Cons, and Must-Know Maintenance Tips
If you’ve been thinking about upgrading your backyard pool or planning a new installation, chances are you’ve come across the saltwater vs. chlorine debate. Saltwater pools have surged in popularity over the last decade, and for good reason—but are they really better than traditional pools?
As swimming pool experts with years of hands-on experience in residential and commercial pool systems, we’re here to clear the (salt) air. In this blog, we’ll dive into the pros and cons of saltwater pools, how they work, and what kind of maintenance tips you need to know before you take the plunge.
🔧 What Is a Saltwater Pool?
Contrary to popular belief, saltwater pools still use chlorine—but in a more efficient, skin-friendly way. Instead of manually adding chlorine, a saltwater pool system uses a salt chlorine generator to convert dissolved salt into chlorine through a process called electrolysis.
That means:
-
Fewer harsh chemicals
-
Softer water feel
-
Less eye and skin irritation
But that doesn’t mean they’re maintenance-free.
✅ Pros of Saltwater Pools
1. Lower Chemical Costs Over Time
While the initial investment is higher, you’ll save money over time by not needing to buy chlorine tablets regularly.
2. Gentler on Skin, Hair, and Eyes
Many swimmers report a more pleasant swimming experience—no more red eyes or green hair!
3. Lower Chlorine Odor
Since chlorine is produced gradually and consistently, you won’t get hit with that overpowering chemical smell.
4. Low Daily Maintenance
Saltwater pools tend to require less day-to-day attention compared to traditional chlorine pools—once they’re balanced.
❌ Cons of Saltwater Pools
1. Higher Upfront Cost
Saltwater systems typically cost $1,500-$2,500 to install, depending on the size of your pool.
2. Corrosion Risk
Salt is still a mineral, and it can be tough on certain materials like metal pool fixtures, ladders, and stone coping if not properly maintained.
3. Specialized Equipment Repairs
When something breaks, not every pool technician is trained to handle salt systems. That means higher repair costs and longer wait times.
🧼 Saltwater Pool Maintenance Tips
Even though saltwater pools are considered low-maintenance, they still require attention. Here’s how to keep your saltwater pool clean and clear all season long:
✔️ Check Salt Levels Monthly
Ideal salt levels range between 2,500-3,500 ppm. Low salt = low chlorine production.
✔️ Inspect the Salt Cell Every 3 Months
The salt cell can build up calcium and lose efficiency. A quick rinse with diluted muriatic acid usually does the trick.
✔️ Balance pH and Alkalinity Weekly
Saltwater pools can have rising pH levels. Test weekly and adjust as needed to avoid scaling or cloudy water.
✔️ Shock the Pool as Needed
Yes, even saltwater pools need an occasional shock—especially after heavy use or a big rainstorm.
✔️ Winterize Smartly
If you live in a colder climate, protect your salt cell and generator by winterizing properly. Saltwater systems are sensitive to freezing temps.
🏡 Is a Saltwater Pool Right for You?
If you want a more natural, low-maintenance swimming experience and are ready to invest a little more upfront, a saltwater pool system might be your perfect match. It’s a fantastic option for families, frequent swimmers, and those sensitive to chemicals.
