Here are my test results. This is first time I have noticed CC as -1. I did not do the testing myself as I am teaching someone else to use our test kit and they decided to proceed without me. They may have written down the numbers incorrectly or misread the result. Even so what would I do if the CC was actually -1. Usually CC is zero.
Total Chlorine 2
CH i guess this is Calcium Hardness which i do not test as liner is vinyl.
By the way it seems every time I test my pH is 8.0. Why is that and what may be done about it besides adding Muriatic Acid (about 3.37 cups)?
Thanks in advance for the assistance.
