I did the same thing the first time I tested. But when I did it right the reading didn't change...hmmm...
But my card says as follows:
1. add 10 drops of #1
2. shake solution
3. shake #2 for 30 sec.
4. add 10 drops of #2
5. shake solution one min.
6. wait five min.
7. read
Did you shake after adding #1? Did you wait five minutes before reading? I screwed that whole thing up the first time I did it...hehe
