using gtound limestone on substrate

[foghog]

does anyone or has anyone used ground limestone or lawn lime on the substrate as a cheap form of calcium for snails?

I use powdered limestone, but in block form, not sprinkled over the substrate. My snails love it so much they ignore the cuttle.

I was advised by a horticulturalist that "lime" means something different than "limestone" in landscaping parlance. In this sense, lime is caustic and would kill snails in a very nasty way. He advised me to make doubly sure I was getting limestone and not lime for my snails, and I pass along his advice to everyone else here.
