Do salt water pools corrode more than chlorine pools?

No, salt water pools are actually less corrosive than chlorine pools. The only metal parts in a saltwater pool that come into contact with the water are the heat exchanger and the salt cell. These parts are made of titanium, which is highly resistant to corrosion. In contrast, chlorine pools use a variety of metal parts, such as pumps, filters, and heaters, which are all susceptible to corrosion.
