 Pure water, that's actually fake news. Pure water is municipal tap water that's in process. You want to see spring water. Pure water bad, spring water good. Correct. When you see high alkalinity, like 9.5 pH, that's actually terrible. You don't want to be overly alkaline. You want to be Goldilocks alkaline, because too much alkaline creates calcium buildup in lead pipes. Who knows what it does to humans. Right. So what's the Goldilocks number that we should be looking for? 7.7 is the number of anything in the zone of 6.7 to 7.7 is kind of the zone. Balance alkalinity. You want to be balanced.
