    Just out of curiosity, when testing for NO3, do you just barely shake the 2nd bottle or do you shake it vigorsously(30 seconds). I ask b/c yesterday I did both ways and each gave me a different reading. When I barely shook it, my reading was 5-10ppm and when I shook it vigorously, it came out 20ppm. Does the extra O2 effect the reading? How do you "shake" the bottle?

    i shake vigorously for 30 sec. and my readings were always around 20ppm until i started weekly water changes then they went down just a bit 10-20ppm. i'm gonna try it w/o shaking so much.

    Vigorously for 30 seconds, and then when nitrate bottle 2 added shake vigorously for 1 minute as the instructions state...
