    CH-Test out of this World?

    1. Rinse and fill the clear plastic cylinder to the 10ml mark
    2. Add 10 drops of R-0010 and mix. Then, add 3 drops of
    R-0011L and mix. Red indicates the presence of Calcium.
    3. Add R-0012, one drop at a time, ‘til color changes to blue. Multiply number of drops times 25. NOTE: If the pool water contains known copper, add two drops of R-0012 PRIOR to adding R-0011Land continue. Count the two drops in your R-0012 total. Record.

    Okay did that...
    Weather cold
    I used the glass one... going to use plastic.... Frig is that why?
    Just used the other mixing tube and now it's 80 drops x 25 so 2000

    93 drops to blue ? x 25 = 2,325?

    Hand swirling...

    Yikes is this possible?
    The pool is crystal clear and no scale..

    That is crazy high for sure. Have you tried a test on your fill water by any chance? Shame you don't have the "Speed Stir". The CH test is one that it really helps with.

    If you have hard water and you've never drained, I suppose it's possible. In the summer I gain about 25 CH per week.

    I will say that my CH dropped 200 points -- roughly 40% -- when I switched to using the speedstir for the CH test.

    When I test (currently I'd hovering around 1000) I start by adding 10 drops of R-0012 and let the speedstir have a full cycle. Then 10 drops of R-0010 and another cycle, then 5 drops of the R-0011 so the color is deeper. And then I add 10 drops at a time until I start getting closer, letting the speedstir run a full cycle each time. I've experimented by not adding the drops beforehand, and only adding two, and using only 3 drops of indicator, and it hasn't changed the facts.

    Use the speedstir and take plenty of time. And then consider a partial drain or reverse osmosis. You're in one of the few areas of the country where that's available.
