The purpose of these stones it to maintain the alkalinity of your water, resulting in adding trace minerals such as calcium, iron, magnesium, potassium, zinc to your drinking water. This absorption of minerals from stones recreates natural effect of the rocks that line fresh mountain streams, generating the same delicious, fresh tasting water.
*The pH of your filtered water needs to be on the alkaline side of the pH scale before the trace minerals from the stones will seep into your drinking water. If your Berkey purified water is neutral (pH7)or on the acidic side of the ph scale (below 7pH), these stones will have no impact on your Berkey filtered/purified drinking water.
