For now , it is probably sufficient to regard calcium bicarbonate as the water soluble form of calcium carbonate (chal ...[text shortened]... wheeler - Brew your own real British ale, page 50.

This is still a matter of some confusion.

Wikipedia is pretty good about this. The chemical formula for calcium carbonate is CaCO3, for Calcium bicarb is Ca(HCO3)2. So the ion for Calcium carbonate is CO3(--) and for bicarbonate HCO3(-), where the minuses indicate that CO3 is doubly ionized and bicarbonate only singly ionized. Apparently calcium bicarbonate only exists in solution (unlike sodium bicarb which does). The page on bicarbonate is probably the place to start and it has links to all the other relevant ones:
