I've been trying to figure out what I'm doing wrong with this calculation. I had previously done it manually, but recently started trying out your software.
I used the Water Profile tool and just did a sanity check to see if your results correspond to my hand-done results.
I put 1 gm of Gypsum into 1 gallon of water.
Usually ppm is defined as (grams of solute / grams of solution) * 10^6 so I did dimensional analysis to get:
Ca weighs 40g/mol and SO4 weighs 96g/mol so the ppm of Ca is 40/136*264 = 78ppm Ca and the ppm of SO4 is 96/136*264 = 186ppm SO4.
When I use your tool I get 62ppm Ca and 148ppm SO4.
What am I doing wrong?

Code:
1g CaSO4 1gal water 1 liter water
---------- * ------------------ * ----------------- * 10^6 = 264 ppm CaSO4
1gal water 3.79 liters water 1000 g water
Ca weighs 40g/mol and SO4 weighs 96g/mol so the ppm of Ca is 40/136*264 = 78ppm Ca and the ppm of SO4 is 96/136*264 = 186ppm SO4.
