What is your KH? Calcium is the main ingredient of KH and without a
proper KH above 80 ppm (or more), any snail will have difficulty
generating a healthy shell.


I have well water and I just did a test for the KH and it is very very low.
My test kit stated to count how many drops of test solution would make the
aquarium water in the test tube bright yellow. It was medium yellow at 35.8
and brighter yellow at 53.7. So I am to assume I probably should not have
snails.
