I don't know if this is the most effective way though.
Other ways to add the needed nutrients for snail shells are to add crushed coral (bumping up your water hardness), or to add montmorillonite clay powder. You can get montmorillonite as a pond additive for koi. Pond Fish & Koi Health & Nutrition: Microbe-Lift CMC Calcium Montmorillonite Mineral Clay
One 2lb jar should last you for the rest of your life because all you need to do is add a pinch's worth per gallon at every water change.
I got a few cuttlefish bones. Do you know if the snails are supposed to eat it or does it just get into the water column? Will the bones dissolve or will they stay after the calcium is depleted?
