Most of us use CaCO3 to control the hardness of our water. It is easier
to measure out specific amounts, and therefore you have a tighter
control on hardness regulation. With Dolomite or a shell, etc. you
would constantly have to measure to adjust. With a regular maintenance
schedule, and early record keeping... determining how much CaCO3 to add
with each water change is a snap.
