    TA Test

    I did this test a week ago when I first received the TF-100 and it was 190. The test worked just like the instructions said, went from green to red. I have tried this twice since and it starts green and then goes clear. I have added 25 drops and it stays clear. Any idea what I am doing wrong? I fill to 25ml, add 2 drops 0007, mix, add 5 drops 0008, mix then start adding 0009 one drop at a time wiping and swirling between drops.

    Unless somebody else believes differently, I would just say that I believe that you haven't reached the endpoint yet.

    After how many drops does the solution become clear?

    For the TA test, anything more or less like red, pink, yellow, or clear is a valid end point. Once the color starts to change to one of those, continue adding drops as long as the color continues to change, the final drop that doesn't change the color any further doesn't count.

    Have you added a lot of chlorine since the first test? That will make it go more pale yellow than red.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Yes. I had it a shock level for about 5 days. The last test was done when the FC level was about 11. With my CYA level I am targeting 9 or 10.
