Actually, I do provide measurements for *calcium* carbonate for acid
reducation in the acid adjustment calculator but it's at the bottom of
the page (and apparently hidden quite well). Maybe I'll swap that
section with the acid increase measurements so both are immediately
visable.

Do you advocate potassium carbonate and/or potassium bicarbonate over
calcium carbonate? Do you happen to know if the measurements for
potassium
carbonate and/or potassium bicarbonate would be the same as those for
calcium carbonate?

Thanks,

Ron
