Nitrite is being produced and processed then as that's the only way nitrate can rise. With nitrate at 160ppm cycles can stall and the nitrite test can become unreliable so do a very large water change to get nitrate down then dose again with ammonia. If your ammonia is at 0 next day and nitrite is also at 0 your tank is cycled.
