I opened my pool this year and my pH tests don't seem correct. The colors that I'm getting don't align with any of the colors on the OTO. At first it was bright red like the original color of the R-0014 phenol red so I figured I just had a very high pH for some reason. I approximated at 8.5 and added roughly 30 oz. of muriatic acid to correct. Now I retest and it's an orangish color that doesn't match anything on my OTO. My R-0014's expiration date is good and it's been stored properly. Any ideas? Is there anything that would make the R-0014 go bad?
