Taylor Fas-dpd test kit

[Mudbogscrambler]

I have a taylor fas-dpd test kit k-1515a. I also just bought the talyor salt pro test kit last week. The k-1515 kit says to use 2 scoops of r-0870. The salt pro kit says to use 1 scoop. Which one is right? I'm doing the 10ml test.
Thanks

One scoop of R0870 powder is sufficient when using a 10 ml sample of pool water for testing.

And it's easy to check to see whether you used enough powder: After performing the FC and CC tests, add some more pool water to the clear solution in the test tube. If it turns pink, there was more than enough powder for the sample.

(Of course, this only works if your sample turned pink when you tested it for FC. If it didn't -- if there's no FC in your pool -- the post-test solution won't turn pink for any amount of powder.)
