Cycle Question

Week two on new 55, fishless cycle started with used filter media. Ammonia added to 2PPM, drops to 0 in 48 hours, my question is after an initial nitrite spike last week to top of the API chart, nitrites are 0 and nitrAtes are sky high....why is my nitrite reading 0 when ammonia is still not dropping to 0 in 24 hours?

Because the bacteria that process nitrites to nitrates often grow faster than the bacteria that turn ammonia into nitrites. So you have enough of the bacteria that turn nitrites into nitrates; now just to wait until the bacteria that convert ammonia to nitrites catches up!
