I have recieved my water report from ward labs and my sulfate isSO4-S 9 I thought I read somewhere on here that I should double that number when inputting it into a water calculator is this true?
You will find that Bru’n Water already has that information noted on the Water Report Input sheet. Yes, you would multiply the SO4-S value reported by Ward by 3 to convert it to its true SO4 concentration. You would also multiply the NO3-N value by 4.43 to convert to the true NO3 concentration.
