I just recieved my Taylor K-1515 test ... having a problem :::
Filled to 25ML
Added 2 dippers ,swirled , it turned real pink
Added R-0871 reagent drops and counted -- 21 to turn from pink to clear
Multiply 0.2x(21) = 4.2
Then is says to add 5 drops of R-0003 -says it would turn back to pink , but it stayed clear???
