Now I know why my snails don't grow too large!!!The  carbonate 
hardness in my tank is ussually hovering around 4 on German scale.
I guess hardness by itself doesn't stop them from reproducing though.
There is just a ton of those suckers around and if I can't see them I 
guess I'll just let them be. Let the mother(aquarium) nature take 
care of them.

I have read that copper is really dangerous when water has very 
little calcium(or other) hardens in it. So I wouldn't try it. Also I 
don't like introducing dangerous chemicals into my tank. But thanks
for the warning. :-)
