I purchased the TF-100 test kit, which comes with the Taylor basic kit for daily tests of Chlorine and pH. I have a couple questions about these daily tests. First my "CYA" level is always between 70 and 80. I don't have any tabs in, or add conditioner or anything. I chlorinate using liquid (household) chlorine. But because the CYA is a little high, i guess my target chlorine is around 8. The thing is, the basic daily chlorine/pH test only goes up to 5. So...
1) Is it normal for the CYA to be staying around 70?
2) Is there a better test kit for daily tests of chlorine? I mean besides the DPD. I don't want to go through all my drops.
