Am having similar pH issue. I've the TF-100 Test Kit. When I measure chlorine & pH using the Taylor Basic k-1000, it shows Cl Br at the 1-2 level, and pH at the 8.2 level. When I use the Test Kit, TA is at 60, and CYA is at 40. Maybe I'm not using the CYA View Tube correctly: I fill it until I cannot see even the outline of the black dot; until the black dot cannot be seen at all. Do I go too far? The CH reads 350. I didn't do TA as it is below 5 ppm. I've a SWG. Suggestions most welcome.
