    CH Test

    For some reason adding another drop of R-0011L seems to help me with the color shift to blue. Is there anything wrong with accuracy by adding another drop? Even thought about adding 2 drops of R-0011L to see what happens.

    You're using 3 drops in 10 ml water?

    Yes, you can use 4 or 5. I do.

    Keep adding drops until the color doesn't change...then just don't count that drop.

    Yes I had been using the default 3 drops of R-0011L with 10ml water but decided to try an extra drop. My CH test has never just crisply turned from red to blue as far as I can remember. Always have a purple before getting there, at least that's what my memory says. My reagent is getting old too though. I have some new on the way.

    Mine takes a long time to go from red to blue, too. The speedstir helps a lot with the intermediate colors. Another cycle will push usually push it one way or the other.

    You can go 5 no problem. It helps on this test and the same with TA. Put a few extra drops in there and see if it helps. It will no hurt your results at all on these two.
