The chlorinator generates a very low voltage current passing through plates known as the electrode. This creates electrolysis; salt and water break up into hydrogen gas and hypochlorous acid. The hydrogen gas simply leaves the swimming pool water in the form of small bubbles. The hypochlorous acid sanitises the swimming pool. In essence, a salt chlorinator creates chlorine. The pH on this production is extremely high and salt pool owners usually require high amounts of pH reducing products to balance the outcome. This is also how Liquid Chlorine is created.
