How long have you been fish less cycling the aquarium? Are you using a liquid test kit or strips? The nitrate test in the API liquid kit needs to be done exactly as the instructions and you need to shake bottle number to really hard as the reagents form on the bottom of the bottle which can produce a false negative.
