are you sure your not geting the nitrites and nitrates confused? Unless you are doign soemthing to kill the beneficial bacteria you should have ammonia and nitrites with a few nitrates if your tank is cycling, you could also have 0 nitrates if the bacteria that consumes the nitrites is not in place yet. Can you give us any more details on what you are doign with your tank, are you dchloriinating your water. Sounds to me like you have either a really slow cycle, or the ammonia you are using for the fishless cycle is not pure ammonia.
