Have you added any bacteria from another cycled tank? Works best from a cycled tank. If not, you will not get any no2 reading for a while yet. Ammonia should be starting to come down. NH bacteria can multiple every couple hours but no2 bacteria multiple only every 2-3 days. My 90G took 4-6 weeks to cycle because I did not add any bacteria except bottled stuff. NH bacteria did fine but it took forever for the no2 bacteria. Patience is the key.
