1st Year Pool owner. We live 25 miles from town, so running back and forth to the pool store is not feasible. However, we have done so a few times to get a "professional" read on our water. However, the two different pool stores have different results, as well as different acceptable ranges, so we don't know who to trust or where our numbers should be. We are trying to get a handle on pump run time, SWG chlorinator % setting, and proper chlorine and CYA levels. Our chlorine level seems to be varying widely from day to day and also morning to evening. I have purchased the Taylor FAS-DPD Chlorine test kit, and it seems pretty straight forward. I have a few questions. First, if done correctly, is the Taylor Test Kit the most accurate way to keep water in balance? Second, on the TFP SWG Water balance page, it indicates the CYA range to be 70-80, while the pool store indicates 20-50. TFP also recommends chlorine be 3 - 5, while pool stores indicate 1 -2. Why the CYA and Chlorine differences?
