I've tested our tapwater repeatedly and it does not register on the test kit. Always shows zero. Our local water district actually won awards for having the best (quality) water in the United States.smithrc said:If you've not got plants then its impossible. Tap water will have 'some' nitates in it - it would cost way too much for the water company to remove them compleatly.
With weekly water changes, my tanks still register, though, at 5ppm. So I agree that it is strange that your nitrate readings are at zero.
