    TF100 calcium hardness test

    Matt, So it looks like adding a couple of extra drops of R-0011L helped a lot. 27 drops of R-0012 is what I counted which equates to 675 ppm which is a much more likely reading. Do these extra drops of R-0011L change the multiplier at all?

    TF100 calcium hardness test

    Matt, I'll try this but also note that I had just filled the pool last July so less than a year ago. Other neighbors I've talked to have values less than 400 ppm and have not changed their wafer in well over a year, maybe two.

    TF100 calcium hardness test

    Thank you! Yes, I am using a speed stir. So why would my test read over 1250 ppm but Leslie's reading at 400 ppm? They did the test twice with two different people.

    TF100 calcium hardness test

    I recently bought the TF100 test kit and have been having trouble with the CH test. When I test it, my sample never turns from red to blue even after going as high as 50 drops of R-0012. At first I though that my calcium levels were through the roof but then I took a sample to Leslie's and it...
