Ha... sorry I was only half joking when I said that as I read it somewhere else and figured it was maybe a certain type of shell, now I've read that sea shells are 95% Calcium carbonate.
So would that work?
Edit: Sorry, just read Rons last post and he states that calcium carbonate does not work as well.
