Welcome to the Ask and Expert forum.
Did you try using a search engine to find your answers? Most questions like the ones you asked can ususally be found by some web searches. The wikipedia is often a good place to get some quick background material and here is the one on Calcium Bicarbonate http://en.wikipedia.org/wiki/Calcium_bicarbonate

Because Calcium Bicarbonate only exists in a aqueous solutions, finding an appropriate concentration and purity for your purpose might depend on what you are planning to do with it.

Aquarium supply stores typically stock it in concentrations appropriate for use in maintaining acquarium pH, calcium, and total alkalinity.

You can also make Calcium Bicarbonate from mineral water, carbonic acid, and calcium carbonate if you are doing something like trying to grow some stalactites, stalagmites, or other calcium carbonate structures and here is one article on one method: http://www.knaw.nl/ecpa/ink/docs/PDF%20 ... ate_OK.pdf. Note: This method will produce a solution that has Calcium Bicarbonate and other disolved minerals in it so it won't be reagent quality but if you are trying to mimic what goes on in a cave, it will closer than a pure Calcium Bicarbonate and disolved CO2 aqueous solution.

So it really depends on what you actually trying to do as to how you obtain your Calcium Bicarbonate.
