Ah.. Also I have a "Brita" water filter attached to my sink in my kitchen.... Tested the PPM Of it and its 178.... I read somewhere that the Brita filter would take out most of the contaminants like chlorine.... Should I still boil the water after it comes out of the Brita Filter? Or Boil it and then leave it for 3 days? Where is the cal-mag involved in this?
