We are drawn to the SWG for the soft water and no smell of chlorine but yesterday a PB (not ours as we are doing it ourselves) mentioned he would do the ECO smart system. We had never heard of this before. We r struggling to find info on this but he swore by it. Need some advice on which we to go. We live in prob the hottest part of the country with our summers reaching upwards in the 110-115 F. He mentioned SWG will require additional chlorine additives due to our extreme heats in the southwest. Would this deter you from a SWG system and does anyone have experience with the ECO smart systems?
