Calcium hardness

[Cherylr]

Hello Friends,

My CH reading is 0 and I have an above ground vinyl liner pool. Seems like I remember reading that CH is most important in concrete pools where leaching will occur if the CH level is too low or with cloudiness if the CH level is too high. Do I need to worry about getting my CH level to the recommended 50? I use the good test kit I ordered from y'all and I repeated the test for accuracy.

Thank you for your help.

There is no known reason to add calcium to an above ground pool. The minimum is listed as 50 because we don't have enough experience with levels below 50 to be absolutely sure what will happen, still there is no reason to suspect that there will be a problem.
