so what you are saying is 4-6 weeks...or less....or more...JK:p
The best answer is it takes as long as it takes. you will see a spike in ammonia. it will start to go down and you will see a rise in nitrites. they will go down and you will start to see a rise in nitrates. your tank is cycled when you see only nitrates. do a 50%-75% water change and you are ready to go.
My best advice is when you think it is finished go another week. Time and patience is everything in this hobby. Plan plan plan there is no such thing as a good impulse decision in this hobby.
there is a lot that can influence that time. I did not see any cycle in my first tank because I used LR
from a tank that was being torn down.
