Got the pool up and running this year shocked it from green to clear everything is great, but when I did the test with my Taylor K2006 all of the colors were way off. I know for a fact there is chlorine in the pool, I can smell it, but I can add R0870 powder and I can never get pink. My pH test is so low I'm guessing around 5, very light yellow. And for TA, when I add the first drop of our R0007 it immediately turns bright red, not green! Is it just time for a new test kit? This is last years, but was kept in a cool dry place. Or am I just doing something wrong? Or is this something in the water that causes all of the colors to go haywire?
