5 Things to Know About Saltwater Pools and Chlorine

Saltwater pools still need chlorine A saltwater pool generates chlorine from salt; it is not chlorine-free. You must maintain a chlorine residual of 0.5–1.0 ppm.

Mineral systems reduce chlorine but don’t replace it Systems like Nature2 or Frog lower the amount of chlorine needed, but they do not eliminate the need for it entirely.

Ozone systems lack lasting residual Ozone kills bacteria on contact but leaves no protective residual in the water. Without a small chlorine level, your pool is vulnerable to contamination.

Water chemistry stays the same Balance pH between 7.4–7.6, alkalinity 80–120 ppm, and calcium hardness 200–400 ppm. Test weekly at minimum.

Don’t treat mineral systems as chemical-free shortcuts They are low-chlorine systems, not no-chlorine systems. Marketing claims otherwise are misleading.
