How much magnesium in my water?
A while back I called the water company in my town to ask for water parameters. I was told that total hardness was 98 ppm and calcium hardness was 67 ppm. I did find an explanation on the web on how to calculate the amount of magnesium but I'm not sure if its correct or if I did it correctly.
98 ppm - 67 ppm = 31 ppm magnesium hardness.
31 ppm / 4.1 = 7.56 ppm magnesium
I don't understand the difference between magnesium hardness vs. magnesium in the water. I'm not sure why they described dividing by 4.1 either.
My objective is to determine if my water provides sufficient magnesium in ratio to the calcium that is in the water. I'm also thinking that my water is soft at 5.488 GDH.
Any advise from folks with chemistry skills would be appreciated.
