Kits with a separate chlorine neutralizer that use them in the pH test are a half-baked attempt at making things work. More neutralizer is not better, especially when the chlorine level is < 5 ppm. Again, get a proper test kit. There is absolutely no excuse for it and I don't mean just the pH test. Without a FAS-DPD chlorine test it is impossible to do an accurate overnight chlorine loss test or even a 24-hour test to accurately determine chlorine demand nor is it possible to know if you have a Combined Chlorine (CC) problem with any reasonable degree of accuracy. And, of course, if you ever need to shock the pool, without a FAS-DPD kit you will be clueless as to the actual FC level (unless you significantly do dilution ratios for DPD for very rough accuracy).
