A: Ammonia and nitrite levels need to spike during the cycling process in order for the cycle to continue and finish it's task. If you perform a water change to reduce these levels while the aquarium is cycling, you will only be delaying the completion of the cycle. You will reach the end result (a fully cycled tank) much earlier if you do not perform a water change until the ammonia and nitrite levels drop to zero, and the nitrate level starts rise.
