I am in Orlando FL and recently had a pool built. The pool was filled in January and I have been running the chlorine generator for about 1 month. I was relying on pool store tests, but I just received my TF-100 test kit with results below:
Free Cl: 4
Everything looks ok (as far as I can tell) except the CH level. Should I be concerned about the CH, or anything else? What can I do to keep the CH in check?
Thanks in advance for any advice.....
