When doing the FC test, how clear should the water in the tube be?

[aces79]

Okay so doing the FC test the water turns pink, then you add the drops until it turns clear.

How clear? Should it have no pink hue at all?

Does a light, light pink hue mean I need to add more drops and wait fir it to lose all the pinkies?

It should be clear clear. When that happens, you are done with the test. If you let it sit for a minute or 3 after, it will begin to turn back pink. Do not keep chasing it. You are done the first time.

Mine is usually clear with a bit of a gray hue from the powder I'm guessing. Is that okay?

Any of the tests, when the color does not change when you add the next drop, you’re done.

I tried cleaning mine and the little black dots stuck to it just will not come off. How do you get all the residue off of it?

Try cleaning it with rubbing alcohol or bleach - not both at the same time though.
