I'm giving serious thought to purchasing an SWG. I swam in someone's pool who has one, and i really do like the way the water felt. I also like the idea of less maintenance.
When I talked to a store that sold them, he indicated to me that the downside was you have to be constantly adding more acid because it raises the PH. What is the approximate desired PH level with a SWG pool? Any rough idea of about how much acid I would need to add with a 20k gallon pool?
I guess my main issue is, will I be trading less chlorine for more acid, and if so, is it basically a wash with maintenance?
