Just make sure if buying from a well drilling outfit that it is
calcium or southern bentonite, and not sodium or western bentonite.
Well drillers normally use western (sodium ) bentonite and yes that
too is available in 5 gal pails in granulated, and pelleted
forms.........CALCIUM or SOUTHERN is what you want not WESTERN or
SODIUM.......

Why is that?
