Salt water pools do have chlorine in them, but the chlorine level is typically lower in a salt water pool than in a traditional chlorinated one. The chlorine in a salt water pool isn’t actually added by you, but rather is created within a salt water chlorinator or salt water generator. The lower chlorine levels in salt water pools make it less likely for your skin to dry out.
Freshwater pools are virtually the same besides the fact that in Salt water pools you have a salt water chlorinator put the chlorine in your pool for you, while in a freshwater pool you have to manually put in your chlorine for your pool.
Besides the initial increased starting costs that come with a salt water pool, it is mostly personal preference whether or not you choose salt water or freshwater for your pool.
The cost debate between salt water and chlorine pools is very heated. It is cheaper to own a salt water pool up front and you will save money on chemicals each year. But does the cost advantage still exist three years down the road? After a few years, most owners of salt water pools find themselves replacing wood decking and metal parts, as well as a pool’s chlorine generator cell.
