about my cycle

How long should it take for my nitrites to show up? I have had my tank setup for about 10 days now with ~40Lbs of live rock sitting in it. My ammonia showed up real quick and is headed down quickly, but my nitrite tests don't even change the color of the water, am I doing something wrong?

Any nitrite test I've ever used changed color (usually greenish) even when my nitrites were 0. Maybe the test is faulty?
