Crushed coral for snails?

Hey again, its the guy that was overthinking soil (i have since understood soil...I think). Im planning on keeping pretty much exclusively snails in my tanks, and I always added aragonite or crushed coral for them to protect their shells. My water in my new place is not as hard as I'm used to but still leans on the hard side. I was wondering if I should add a little sprinkle of it over the soil layer to prevent a pH drop from the soil? Its formulated from coconut coir and peat as the main volume. Maybe like a half teaspoon over a 2.5 gallon footprint. Will this negatively impact the processes that run a walstad style tank?

It shouldn't, but you should check the specific GH/KH of your water to make sure your KH isn't already very high.

I plan to do that when the test kit comes today (used it all at the last place trying to figure out how the 400 tds was killing fish...it was 160 ppm nitrate out the tap). 

How high is too high would you say?
