e/Saltwater pool

Information
has gloss	eng: Saltwater pools use dissolved salt (1,800–6,000 ppm) as a store for the chlorination system. The chlorinator uses electrolysis to break down the salt (NaCl). The resulting chemical reaction eventually produces hypochlorous acid(HOCl), and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools. As such, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine. The important distinction is that saltwater pools lack chloramines, referred to as Combined Chlorine. Chloramines are the irritants which give traditional pools the stigma of burning eyes and caustic smell. The electrolytic process burns off chloramines in the same manner as traditional shock (oxidizer). When chlorine levels are low in the pool, one possible cause is low salt (others can be higher-than-normal chlorine demand, low stabilizer or mechanical issues with the generator itself.) Salt count can be lowered due to splash-out, backwashing, and dilution via rainwater.
