I'm not sure what waiting six months does. Never heard that one before. It is about the levels of ammonia, nitrites and nitrates, not so much time. Typically you are looking at 4-6 weeks.
If you started with zero everything...got ammonia and nitrites,...got nitrates and eventually the ammonia and nitrites went to zero, but nitrates were high, you are good.
