I'm sorry for the confusion. I'm a new pool owner and have been told that there are 2 ways to change a pool to salt water, from chlorine. An example is using a basic Hayward Aqua Rite system and then I guess there is a more costly, automation system that has more features. Do you know what I'm talking about, by chance? Either way, I think I'm sticking with Hayward purely because of the good feedback I've gotten from the company.
