Ken Schwartz has written a primer on water chemistry at

His recommendation for London Water (per US gallon, 3.78 l, of distilled

English Ale -- A London well-water profile.  3.7 grams Epsom salt, 2.9
grams baking soda, 2 grams chalk (add to mash), 2 grams canning salt, 0.3
gram gypsum. Ca=46, SO4=85, Mg=19, Na=83, Cl=64, CO3=173, Hardness=195,

You could add the chalk directly to the water rather than the mash and then
bubble CO2 through it to dissolve it.  This mimics nature, where CO2
saturated rainwater percolates through limestone.
