To salt or not to salt—that is the question! And no, we’re not talking about seasoning your dinner. The real question pool owners are asking is: “Should I convert my swimming pool to a salt water system?” Maybe your neighbor just switched to salt and can’t stop talking about it. Or maybe you’re tired of hauling heavy chlorine buckets around. Whatever your reason, before diving in, it’s important to understand how salt systems work, what their benefits are, and what common misconceptions surround them.
How a Salt Water System Works
A salt water pool doesn’t eliminate chlorine—it just generates it differently. When you install a salt system, you add food-grade pool salt directly to the water. The system’s salt cell, also known as a chlorine generator, converts that salt into sodium hypochlorite, a pure form of chlorine. As water passes through the cell, the chlorine continuously sanitizes your pool, killing bacteria, breaking down organic material, and helping maintain consistent chlorine levels. This means your pool sanitizes itself automatically, requiring less manual dosing and more consistent water quality.
Benefits of Converting to a Salt Water Pool
Convenience
One of the biggest advantages of switching is convenience. You’ll no longer have to lug home heavy chlorine tabs or remember to restock during peak season. The system generates chlorine continuously as long as salt levels remain within range. You also won’t have to rely on friends or neighbors to maintain your feeder while you’re away on vacation—the system does the work for you, keeping your water clear and sanitized.
Softer, Gentler Water
Many pool owners report that salt water feels softer and less irritating on the skin, eyes, and hair compared to traditional chlorine pools. That’s because salt-generated chlorine is purer and doesn’t include the binders and stabilizers found in tablets. This makes swimming more comfortable, especially for families with sensitive skin.
Reduced Chemical Handling
Salt systems minimize direct contact with harsh chemicals. You’ll still need to test your pool water and balance chemicals occasionally, but the overall exposure to irritants is far less.
Common Misconceptions About Salt Water Pools
“Salt water pools don’t use chlorine.”
This is false. Salt systems generate chlorine; they just do it through electrolysis rather than manual dosing. The chlorine produced is cleaner and more consistent, but it’s still chlorine doing the sanitizing work.
“I won’t need to add any chemicals.”
While salt systems simplify maintenance, they don’t eliminate it. The salt cell produces chlorine with a naturally high pH of about 14, which can cause your pool’s pH to drift upward over time. You’ll still need to monitor and adjust pH, alkalinity, and stabilizer (cyanuric acid) levels. Routine algaecide and phosphate testing may also be necessary, particularly for pools with high foliage or frequent algae issues.
“It’ll taste like the ocean.”
Not even close. Ocean water has around 40,000 parts per million (ppm) of salt, while pool systems only use 2,800 to 3,500 ppm. That’s less than one-tenth of ocean salinity. Properly balanced, most swimmers can’t even taste the salt.
“Salt systems are much cheaper to run.”
This is partially true. You’ll save roughly $200–$300 per year on chlorine tablets, but other costs balance out those savings. Salt cells typically last 4–5 years and cost between $800 and $1,200 to replace. You’ll also need to add salt periodically and maintain proper chemistry. In the long term, it’s best to think of it as spreading out your chemical costs rather than eliminating them.
Potential Drawbacks of a Salt Water System
Salt water systems require an upfront investment for installation, typically ranging from $1,500 to $2,500 depending on your pool size and brand. They also require electricity to power the chlorine generator, which adds slightly to energy costs. Additionally, salt water can be mildly corrosive to metal pool parts, ladders, and some stone surfaces if not properly maintained. Using corrosion-resistant materials and keeping salt levels within range helps prevent damage.
Is a Salt System Right for You?
If you value convenience, smoother-feeling water, and consistent chlorine levels, a salt system is an excellent upgrade. However, if your primary goal is to save money or eliminate maintenance entirely, it might fall short of your expectations. Salt water pools still require testing, balancing, and occasional adjustments—just with less day-to-day hassle.
Recommended Systems
If you decide to make the switch, a trusted system like the Pentair IC20 or IC40 offers reliable performance, easy maintenance, and compatibility with most in-ground pools. These systems are durable and efficient, helping you achieve balanced, crystal-clear water year-round.
FAQs About Salt Water Pool Systems
How much salt does a pool need?
Most salt water systems operate best between 2,800 and 3,500 parts per million (ppm). For reference, that’s about 40 to 50 pounds of pool-grade salt for every 2,000 gallons of water. Your system’s manual will specify the ideal range.
How often do I need to add salt?
Salt doesn’t evaporate or get used up—it only leaves the pool through backwashing, splash-out, or draining. Typically, you’ll only need to top off the salt once or twice a season.
Can I convert any pool to salt water?
Yes, nearly any existing chlorine pool can be converted by adding a compatible salt chlorination system. Both above-ground and in-ground pools work well, though you may need to check equipment compatibility—particularly heaters and metal fixtures.
Does salt water damage pool equipment?
When properly balanced, salt water isn’t damaging. Problems arise when salt levels are too high or when metal parts aren’t corrosion-resistant. Using quality stainless steel components and sealing any porous stone around your pool prevents issues.
How long does a salt cell last?
A chlorine generator cell typically lasts 4–5 years with regular cleaning and maintenance. Scaling or mineral buildup can shorten its lifespan, so it’s important to inspect and clean the cell a few times each season.
Can I still use shock or algaecide in a salt pool?
Absolutely. Even with a salt system, you may need to shock your pool after heavy storms, high bather loads, or visible algae growth. Non-chlorine shock is often preferred since your system already produces chlorine.
Will a salt system affect my pool’s pH or alkalinity?
Yes. The chlorine produced by the salt cell has a high pH, which can gradually raise the pool’s pH level. Regular testing and balancing with muriatic acid or pH reducer will keep your water within the ideal range of 7.2–7.8.
Can I use any type of salt?
No. Only use pool-grade or food-grade salt labeled for use in chlorine generators. Avoid rock salt, table salt with iodine, or anything with anti-caking additives, as they can damage your system or leave residue in your pool.
Does a salt water pool feel different?
Yes. The water feels silkier and softer to the touch, and it’s less likely to cause dry skin, itchy eyes, or strong chlorine odors. It’s one of the biggest reasons many pool owners switch.
How much maintenance does a salt water system require?
Although easier overall, salt systems still require regular care. You’ll need to test your water weekly, clean the salt cell every few months, and monitor pH, alkalinity, and stabilizer levels.
Can I convert back to chlorine if I change my mind?
Yes, you can easily switch back. Simply remove or bypass the salt system and return to using chlorine tablets or liquid chlorine.
Final Thoughts
Converting to a salt water pool isn’t just about following trends—it’s about improving your swimming experience. You’ll spend less time handling chemicals, enjoy softer water, and maintain more stable chlorine levels with minimal effort. Still, every pool owner’s needs are different. Consider your pool size, usage, and maintenance habits before making the investment.
