So- is there a reason why most PBs are opposed to SWGs? We are in the process of planning a new build (1st time) and everyone is talking us out of it- however no consistent alternative. Some say ozone is better, some say bromine, some say UV plus ozone. I dont know who to believe. I have severe asthma and skin allergies and cant stand regular chlorine water, and love the feel of salt water. Actually, also helps me breath better. But really getting scared off by the PBs being so strongly against SWGs since we will be novice pool owners.
