The Nitrogen Cycle does not happen only once. It is a continuous process but the first cycle of a new tank is very critical cause it has to start with lots of toxins which are the 3 you mentioned. Once there is enough bacteria, nitrite will go down with nitrate as the byproduct. Changing water is the simplest way to get rid of nitrate. That is why you need lots of ammonia at the beginning so it will create enough bacteria. The quickest way is to put a shrimp inside the tank to rotten for a week enclosed in a nylon panty hose or similar. Another way but will take a little bit longer is to put very hardy fish like damsels to have their waste form into ammonia.
