Why doesn t the pH setting of the unit match the alkaline / acidic water based on the pH reagent chart?
Your source or tap water may already have an alkaline or acidic property to it. The unit is calibrated for neutral 7.0 source water. So if your source water has an alkaline property, your ionizer will intensify that alkaline property even more. If your source water has an acidic property, the alkaline ionizer effect will not be as intense because of the counter action. Other variations also include the lack or surplus of natural minerals in the source water which is an important part in creating alkaline ionized water.
