Re: [APD] Potassium bicarbonate

Found some on-line at Spectrum Chemical
(http://www.spectrumchemical.com/retail/), but it's rather dear. My well
water is extremely soft and acidic and I am currently ammending it with a
mix of calcium carbonate, sodium bicarbonate and magnesium sulphate and have
ocassionally worried about an excess of sodium in the system. USP is
pharmaceutical grade, is it not? I know what you mean about the funny looks,
etc., as I've gotten a few of those myself. Cover stories have included
model rocketry and science fair projects for the kids, but have yet to hit
on one that was foolproof.
