I just tested our pool with my newly arrived TFT kit and got a TA reading of 210, when I test with my Taylor K-2006 kit (1.5 years old) I get a TA of <75. Would old chemicals not give me a falsely high result instead of a low one?
I do notice that the drop sizes from the TFT kit R-0009 do look smaller than the drops from any of the other reagent bottles.
Test strips also 1 year old are in the range of <75 as well.
Dont know what to trust now. Please help
