Salt Chlorine Generators - Taylor Technologies

Calcium hardness is tested with a drop-count titration. Test strips will measure total hardness (calcium plus magnesium hardness), and colorimeters may be used for the calcium test. Because the chlorine from a salt chlorine generator is pure and is not coined with additives found in solid products, this form of chlorination does not affect total alkalinity or calcium hardness directly.
