Water Chemistry Calculator

This is the Javascript version of my water chemistry calculator. It calculates the ppm of all the important brewing ions based on the water volume and the mass of the salts you add. Enter a number for each salt you want to add (under the Mass Added column) and click Calculate.

Volume (gal)

Mass Added (g) PPM (mg/l) Added
CaSO4 (gypsum) Ca++ (calcium ion)
NaCl (table salt) Mg++ (magnesium ion)
CaCO3 (chalk) Na+ (sodium ion)
MgSO4*7H2O (epsom salt) SO4-- (sulfate ion)
CaCl2*6H2O CO3-- (carbonate ion)
