The water company told me that their test was much more accurate than any fish aquarium test kit and suggested the API nitrate test kit was picking up on something else in the water (perhaps safe nitrates) and was showing up as a nitrate reading.
I will try the longer shake and see what happens.
Byron, are there any nitrate test kits recommended over the API? The color chart is so hard for my to follow on the API and I do not like how the chart jumps from the safe 40 ppm all the way to an unsafe 80 ppm, with the colors looking the same. | All recommendations I've come across are for the API kits. Nutrafin (Hagen) also make kits, I have their pH kit as a second to my API, but I've never used their nitrate one. The concensus on the other forum was that API was OK, but the regeant needs to be shaken 2+ minutes.
I would expect a water company's tests to be more accurate that our test kits. Let us/me know if you get different results now.
