    CYA test discovery

    I've been having fits testing CYA ever since I've been doing BBB.
    I never felt good about the readings and thought the test was too subjective.

    I finally broke down and bought the standardized 50ppm sample.

    I've been playing with it all afternoon and found that if I hold the test beaker at chest level, rather than waist level, I can nail it every time.
    When I did it this way with my pool water I found I have about 25-30ppm rather than the 50 I thought I had.
    I've been using more chlorine than seems right. I'm going to add about 2 lbs of stabilizer this afternoon.

    You might find you need to test at waist level, under your chin or down around your knees. It depends on your particular vision.

    I highly recommend getting the standard solution. It will show you the right way to test...IMO

    I am not sure it has as much to do with your vision as it does with the intensity of the light you are in.
    Thanks for the observation though.

    I just got some of the standard solution as well, but have yet to experiment.

    You may be right about the intensity of the light.
    Whatever it was, holding the test beaker about 8" under my chin worked. Holding it at waist level didn't.
    I wouldn't have known that without the solution.

    Ah I see. It's more to "calibrate" your own testing with the real regaent?
