What is PH+9 Alkalized Water?

There are numerous claims of the health benefits when drinking water with an elevated PH  or Alkaline content. At Water Shack we start with our Purified Drinking Water and infuse natural minerals (Magnesium, Potassium, and Calcium are the primary 3) which brings the PH Balance up into the high 9s. This method maintains the higher PH even when stored for months prior to using. Always keep your bottles of water out of the sun light, and we recommend the use of BPA Free Bottles or Glass.
