How it works
Water flows through a cell with electrodes. The current splits the salt and produces free chlorine, which disinfects the water. The chlorine then turns back into salt. So the salt is not used up; you top it up only when water leaves, for example when backwashing.
How the water feels
The water has a little salt, much less than the sea. Most people cannot taste it. Eyes sting less and there is no strong chlorine smell, because chlorine is made steadily, without peaks.
With automatic pH control
Salt chlorination slowly pushes the pH up. A dosing pump that measures and corrects pH closes the loop: the water stays balanced without daily testing. That also protects the liner.
What to watch
- Metal parts (ladders, lights) must be stainless of a suitable grade.
- The cell is descaled once or twice a year, especially with hard water.
- In great heat or after a party, a chlorine shock helps.
