Bests & Worsts Reviews from Amazon

Every time I boil this water to make tea there would be a strange chalky residue left behind. At first I thought it was some sort of dust or maybe somebody had used the pot before I made the water, so I would clean the pot and tried a different brand of water like Poland Springs or Deer Park and when I would use the pot or even my kettle the water would boil and there would be no residue. I'm definitely avoiding this brand in the future!
