Instead, a saltwater pool is a swimming pool that uses salt and a salt chlorine generator (SWG) to produce chlorine automatically, rather than requiring the pool owner to regularly add chlorine tablets, liquid chlorine, or granular chlorine.
The system works by dissolving ordinary pool salt into the water (typically around 3,000–3,500 ppm, which is about one-tenth the salinity of seawater). As the water passes through the salt cell, a small electrical current converts the dissolved salt into chlorine. That chlorine sanitizes the pool by killing bacteria, viruses, and algae. After doing its job, the chlorine converts back into salt, and the process repeats continuously.
Why do people convert to a saltwater pool?
There are several reasons homeowners choose to convert:
1. More Consistent Chlorination
A salt system generates chlorine every time the pump runs, maintaining a more consistent sanitizer level. This helps prevent large swings in chlorine concentration that can occur with manual dosing.
2. Less Maintenance
Instead of adding chlorine several times a week, homeowners simply adjust the output percentage on the salt system. Most routine maintenance involves periodically testing the water and cleaning the salt cell when necessary.
3. Softer, More Comfortable Water
Saltwater pools are often described as feeling "silkier" or "softer" on the skin. The relatively low salt concentration can also be less irritating to the eyes and skin than poorly maintained traditionally chlorinated pools.
4. Reduced Chlorine Odor
A properly balanced saltwater pool usually has very little chlorine smell. The strong "chlorine odor" people often associate with pools is typically caused by chloramines, which form when chlorine combines with contaminants—not by chlorine itself.
5. No Handling of Chlorine Products
Owners no longer need to routinely buy, transport, or store chlorine tablets or liquid chlorine. The salt added to the pool is consumed very slowly and is generally only replenished when water is lost through backwashing, splash-out, leaks, or draining.
6. Lower Long-Term Chemical Costs
While the initial purchase of a salt chlorine generator is a larger investment, many pool owners find that ongoing sanitizer costs are lower because they purchase much less chlorine over the life of the system.
Common Misconceptions
"Is a saltwater pool chlorine-free?"
No. A saltwater pool still uses chlorine. The difference is that the chlorine is generated automatically from dissolved salt instead of being added manually.
"Will the pool taste like the ocean?"
No. A typical saltwater pool contains about 3,500 ppm of salt, while the ocean contains approximately 35,000 ppm—roughly ten times more. Most swimmers barely notice the salt, though many describe the water as smoother and more pleasant.
"Can I still shock a saltwater pool?"
Yes. Saltwater pools occasionally require shocking after heavy use, algae outbreaks, or severe storms. Many salt systems include a Super Chlorinate or Boost mode that temporarily increases chlorine production.
Is a Saltwater Pool Right for You?
A saltwater pool is an excellent choice for homeowners who:
- Want more automated pool care.
- Prefer softer-feeling water.
- Want to reduce routine chlorine handling.
- Plan to keep their pool for several years to benefit from lower long-term operating costs.
For many pool owners, the biggest advantage is convenience. Instead of constantly adding chlorine by hand, the salt system automatically produces the sanitizer your pool needs, helping keep the water clean, clear, and ready to enjoy with less day-to-day effort.
