We are installing a Delta UV system in our pool, and I understand that this should help reduce the amount of chlorine needed over a "traditional" pool. If only a small amount (what ever that amount is!) of chlorine is need in the pool, what would be the better way to add it? The builder is installing a Hayward CL-220, and I understand many people feel this is not the best choice, but I figure I will let him install it, and then I can decide later to use it or not. Would this be the best solution, or would another way, like a floater style work better?
