Saltwater pools work by converting salt to chlorine using an electrolytic converter. This produces the same type of bacteria-killing chlorine found in a traditional pool, but in a radically different fashion. Since the salt generator is adding chlorine to the water at a constant rate, it is capable of displacing the bad smell and burning irritation we normally associate with chlorine and maintaining the right amount at all times.
Saltwater pools require far less maintenance than traditional pools and are much less expensive to maintain as pool salt is far cheaper than traditional chlorine. This is a big reason why so many hotels and water parks in the United State have already made the switch. Plus when it comes to initial construction and installation, the additional cost of an electrolytic converter is very small and easily made up in maintenance savings. Even converting an existing chlorine pool to saltwater can be paid off quickly.
