PS, when you put the powder in, if it turns pink with one scoop that's all you need to use (save the other scoop for your next test
If that's really so, that would save a lot on the powder. When I first started using the kit about two weeks ago, I looked on Taylor's website, and they have instructional videos for testing. With the FAS-DPD test, the demonstrator showed that he was putting in two overflowing scoops, in fact it ran way up the handle, and they said that it didn't matter if they were larger, but they said nothing about being smaller. It made me scratch my head watching that, because what's the difference between two level scoops and one overflowing?? So I've been doing two level carefully to conserve, but if one level works, that's even better.
