    Is my Calcium Hardness too low?

    I thought I had soft water, but didn't know how soft. I just did the Calcium Hardness test twice with the TF-100 kit and got a result of 80ppm. My pool is vinyl, but is this too low anyway, and why? Thanks.

    No, It's just fine. CH can be too high (400+) in any pool but can only be too low ( roughly 250 or less) in a masonry (gunite) pool.
