Second question is that I have no idea what the calcium concentration
of my water is. I am starting to infuse CO2 in my little tank to help
my few plants out and I am going to guess that the pH is going to drop
accordingly. What I can do help out my snails? Their shells are all
pretty white now. I have started to use Spring water to fill the tank
as opposed to filtered city water, would that have enough Ca to make
the snails happy? What about taking a bit of a Rolaids and sprinkling
it in the water? How much of a tablet should I use? Should I bother?


Before you start adding stuff to your water, why not find out what's
already in it. does your city water service provide such information?
How provides the spring water? do they tell you what is in it? why
use that instead of city water?

Try a small container of water, add CO2 to it and see what the pH
does, rather than trying it on your aquarium.

If your water really is deficient in calcium, crushed coral is
frequently recommended, probably better than trying to use some
medication intended for people.
