What is the pH of water from the Big Berkey water filter
Is it acidic or alkaline?
No pH value is given in lab test reports. It is said that the Berkey filter reduces pH. The result of course depends on the pH of the water you start with. Get a pH meter for about $10-$20 and measure the pH in your system. If it is acidic, below 7, use baking soda, about half a teaspoon to a gallon of water that has been filtered.
