Calcium Hardness

[mas985]

95" is less than what parts of Arizona and Texas experiences over the year so it really depends on where you live. Check out this Link for where you live to get an estimate.

I experience about 60" with is a full pool volume over the year so my CH almost doubles over the year.

EDIT: I should modify this some by saying that with a pool cover, you can greatly reduce the amount of water lost and thus the buildup of calcium.
