We have a well for water at our new home. Since we had a sulphur
smell, a chlorinator was installed. We had the untreated water tested
and it is safe with no bacteria so our only purpose in adding chlorine
it to get rid of the sulphur smell. We are in the process of trying
to find the level of chlorine that eliminates the sulphur but does not
add too much chlorine. We bought a cheap pool tester where you add 5
drops of OTO to the sample and compare the color to a color scale to
see how many PPM of chlorine is in the water. As we vary the settings
on the chlorine pump, the settings seem to always go from too little
to too much. I would appreciate any advice about how to handle this.

Be cautious about over chlorination and consider this.

You might have better luck with the sulfur odor by just injecting oxygen
derived from (technical or food grade) hydrogen peroxide to titrate the
H2S. A peristaltic pump such as Stenner makes works well.
