How it works

The salt chlorinator passes salty water over plates and produces chlorine by electrolysis. It's still a chlorine pool: the sanitizer is chlorine, only the equipment makes it.

The salt

It needs the right salt level, usually 2,700–3,400 ppm (check your unit's manual). Too little salt and it won't produce chlorine; too much can damage the cell.

  • Add salt with the pump running and wait for it to dissolve before starting the chlorinator.
  • To raise salt: 1 g/L raises it 1 ppm; raising 500 ppm in 50,000 L is about 25 kg.

What to watch

  • The pH tends to rise in salt pools: check it often.
  • Adjust the production % according to use, heat and hours of sun.
  • Clean the cell of scale periodically (per manufacturer).
  • Keep the stabilizer at 30–50 ppm so you don't lose the chlorine you produce.
