I went over to my brother in laws today to test his water with my trusty test kit in hand his pool had some dirt run in it from the heavy rains the other night, he uses 3 inch pucks but he shocked it with 8 gallons of liquid shock 2 nights ago per pool store it is a vinyl lined 20x40 inground and new liner installed 4 years ago and has been using pucks ever since, and I was testing his t/a and the sample turned a light blue when I added reagent r-0008 and then I started adding reagent r-0009 drop by drop swirling the whole time at one point it started to turn red and then it went back to blue and then to yellow and stayed yellow for 25 drops and then I ran out of r-0009......why yellow?? bleach out?
