A color measurement with a reliable device (e.g. Poollab ZWMX1060), gives the best 
indication of the chlorine content in the pool.

Example: your unit has the following values on the screen: pH 7,2 and redox of 740 then 
your pool water has a chlorine content of 1,2 ppm. 
 
 
The parameterization of the electrolysis unit itself is very simple, 
You only have to control the intensity of chlorine creation.
