The basic components of a saltwater pool system include a heater, pumps, salt chlorinator, filter, and control box. The system runs in the summer months, and the chlorinator needs to be checked every six months for cleaning. The salt doesn't evaporate, but the salt parts-per-million level needs to be maintained. The benefit of a saltwater pool is that it makes your skin smoother and is not as harsh on the eyes compared to traditional chlorine pools. However, it still requires maintenance and monitoring of the salt levels.
