i doubt you can make your water too hard for cherry shrimp... i have some of mine breeding in a tank with pure aragonite for a substrate. ph is over 8.4 and gh over 300.

a lot of pet stores and suppliers use RO water to keep their livestock in, so its possible that the marks were already there. i guess its also possible that it just scratched itself on the substrate, though im not sure i have seen a snail do that before...
