I'm sure some have seen my thread about me not having nitrates and then all of a sudden I do.
Summary: The test strips I used to use always gave me around 20ppm. Then I started the API and it always told me 0ppm. At the last wc, API tells me 5ppm on the 20g but not on the other two tanks. I am testing correctly, just like it says on the card. Did I miss something??

When you do the nitrate test properly you will see the color change almost immediately, mine actually is ready for reading in about 2 mins. but I wait the full 5 mins to be safe.
