If you are consuming tap water from a location where levels of a magnesium are sufficiently high in that tap water again, where the level of magnesium is 8.3 to 19.4 milligrams per liter of water, that is, if the water coming out of your tap is hard enough, well then chances are you don't need to enhance the pH of that water or change its magnesium concentration.
