    TF-100 Test Kit

    For the FC test, of the powdered reagent, how much is a "heaping" spoonful of the blue powder? The small jar seems to go real quick or am I using too much of a heaping helping?

    It's probably not much more than you can hold between your finger and thumb.

    The instrcutions tell you the exact amount is not important and it isn't. All you are looking for is the soltuion to turn pink when you put the powder in. In 99.5% of the cases that is a somewhat rounded fill of the CUPPED portion of the dipper.

    How often are you testing?

    You can not use too much, but too little can skew the results. If the water starts with a nice pink, then you likely have used enough.

    I generally use one scoop when my FC is in normal ranges. Today when I was up around 20ppm I added one scoop which made a good pink, but added a bit more to be safe. And I certainly do not try to have a heap over the entire end of the spoon.

    Look closely. One end has a small BB-sized cup in it.
