[Guest guest]

I would like to know where I can get the potassium bicarbonate, I can

easily get the bicarbsoda and citric acid from the supermarket, but

instead of paying huge prices from suppliers I want to make myonw, as i

have found that since I have been useing the alkaline water, my

illness of Crohns disease has improved 80%. I live in australia.
