Saltwater pools still need chlorine.

Saltwater pools are just chlorine pools with a built-in generator. They use a salt cell to convert dissolved salt into chlorine through electrolysis. So you’re still swimming in chlorinated water—it’s just produced on the spot rather than poured in by hand.

Maintenance differs in a few practical ways. You don’t buy, store, or handle chlorine tablets or liquid. Instead, you buy bags of pool salt (roughly $10–$20 per 40-pound bag) and dump it in once or twice a season. The real work shifts to the salt cell: you need to clean it every few months with mild acid to remove calcium buildup, and the cell itself will need replacement every 3–5 years (around $200–$500).

The water chemistry is slightly different too. Saltwater pools tend to have more stable chlorine levels, but pH tends to drift upward and needs more frequent adjustment. You still test the water, still shock it occasionally, and still run the pump.

Overall, it’s easier on your skin and eyes and you skip the chemical store runs. But “maintenance-free” it is not. The generator is another thing that can break.

Saltwater is a nice upgrade, not a miracle.
