Hi 19cuba
It really depends on each of our set ups.
It's kind of meaningless for me to tell you how my tank cycled - if your tank is drastically different. Same goes the other way too.
The traditional ammonia, nitrite, nitrate curves we see in the books normally don't take into consideration the use of any live sand, live rock or other common new tank cycling methods. So sometimes they can be misleading.
Can you describe your tank set up in detail ?
Length of time set up.
Filtration equipment
Use of live rock, live sand or another bacteria starter source.
Any fish ? Dead shrimp method ? Source of ammonia ?
Test kit readings
How are you cycling the tank ?
That may help folks to have a better understanding of your tank cycling / ammonia concerns.
