Hello working on opening the pool here in Ohio. My problem is, when i do the dropper test in the cylinder with the pH on the other side, it shows my chlorine more yellow than the "10" on the tester, but when I do the chlorine dropper test in the cylinder marked "chlorine only" and use the powder as instructed, i keep coming up with the chlorine only at 4 or so and I am trying to SLAM. The powder is a couple of years old and is somewhat hardened, is it possible it is no longer good? Which one do I believe? Not sure if I should add more chlorine or not.
Also, I added CYA last week, levels look good. My pH was high (as usual) so i added acid and it came to a good range, so I started with the chlorine. Then two days later, the acid was super high again, is this because of adding all of the chemicals, did one of them make the pH high? We also got rain in that period, so not sure if that did it?
