Saltwater pools use fewer chemicals but have a higher upfront cost. Chlorine pools are more time-consuming and costly to maintain. There’s less chlorine in the pool, so it’s gentler on your skin and eyes. The chlorine shouldn’t fade or ruin your swimsuit.

The Difference Between Saltwater and Chlorine Pools The water in traditional chlorine pools must be sampled and balanced with liquid or tablet chlorine. Alkalinity, pH and calcium hardness must be adjusted as well. Saltwater pools require the same chemicals except chlorine, although you may need to shock a saltwater pool once in a while.
