Don't bother testing for nitrates until the tank has cycled. Nitrate test kits read nitrite as nitrate and give you a false reading. Wait until the ammonia and nitrite have both gone up and come back down to 0ppm, then start testing for nitrates.

It normally takes around 4-6 weeks for an aquarium filter to cycle.
