Good KH and GH range for nerite snails?

[Thundercracker]

I have nerite snails and don't want them to get mineral deficiencies. I am mainly asking because I was wanting to buy wondershells for my tank, but I don't know if I'm worrying about the snails for no reason. I read the nerite snail care article on aquarium co-op, but it doesn't say a baseline amount for this.

I originally planned on also purchasing coral for KH, but I think that's mainly used for raising pH and the pH of the tap and tank water is higher than 7.0.

If water parameters are needed, I'll be able to provide some tomorrow as it is quite late at the moment.

PH for me is near 7. KH is 60-80 and GH is as high as you can make it.

They were perfectly fine in those conditions for a really long time.

With any invertebrates, it's highly recommended to get a liquid GH and KH test kit.
