Is It true that saltwater pools are maintenance-free?

No, it's not true that a saltwater pool needs no maintenance. However, when operated and maintained properly they generally need considerably less maintenance than a regular chlorine pool. Saltwater pools still need to be properly winterized before closing them and opened when the season started. For routine maintenance, you should test the pH and free chlorine levels every week, the salt levels every month, and inspect the salt cell every three months.
