Why does the TF-100 test kit have a CL test that only goes to FC of 5 (the yellow color test box)?
Seems useless given the CYA/FC chart. Virtually every outdoor pool is recommended to have CYA of 30/40 or more which means the target FC is going to be above 5. My nice, not cheap TF-100 test kit has a key component that is kind of worthless, right?
Sure it can tell me if FC is low, but it's not going tell me if I am on target (based on FC/CYA chart). Why? Am I missing something?
