Generation of Chlorine
Are you really aware of what you are attempting here ...
For a swimming pool can you monitor the total chlorine level in the water in order to maintain safe levels (too much is dangerous, not enough is a waste of time).
See **broken link removed** for a safety data sheet.
See **broken link removed** for a commercial product.
You will need to produce a saline solution, electrolyse it, allow hydrogen to escape safely, descale the electrodes regularly AND measure the pool's chlorine level.
I don't doubt that it can be done but it is a challenge :wink:
