Dear, Dear Contributors, Water softeners = Ion Exchangers are simply for exchange of ions. You will be exchanging a calcium, strontium, ... for a sodium ion. Then water will not be "hard water" rather it will be "soft water" as sodium salts do not deposit like calcium salts. In water softeners or ion exchangers there is no reduction in the amount of Total Dissolved Salts (TDS), as you have exchanged one ion for another one.
