Do they test for total hardness and is that in the report? I have a calculator that can approximate the calcium hardness based on the typical 4 to 1 Calcium to Magneisum ratio (typical well and ground water -- mountain spring water is closer to a ratio of 2.6 to 1).Originally Posted by Rangeball
The formula is Calcium Hardness (ppm CaCO3) = Total Hardness / 1.412 (for a ratio of 4 to 1 and other conversion factors)
[EDIT]Sorry for the wrong factor the first time[END-EDIT]
