The kit I have is the HTH 3-way. As of right now the chlorine level is nonexistent but the Ph is 7.2. The fill water chlorine level is 1 or 2 (hard to tell) and the PH is 7.5. Earlier today the chlorine level in the pool was about 2 and the PH level was 7.2. I will try to find the HTH 6-way test kit but for now I have 3-way with the yellow and red drops. I have not added any chemicals to the pool since last night (HTH Shock). I have just been letting the pump run and skimming the top occasionally today. I am afraid to let the pump run 24/7 because we can't afford a new one so I unplug it in the evenings. The water is still a milky white color but does seem to be a little clearer closer to the top.
