Okay first of all we have moved our pool 3 times so far this summer. The first time it was about 6 inches off. The second time it was about 4 inches off. This time I believe it's between 1&2 inches so I am going to keep it there. However I tested the water and I have a Walmart test kit which I know is not the best but my PH side is purple my chlorine side is a bright yellow see picture below. What do I need to do?
