Put a cocktail shrimp into a media bag or other type of net like bag and let it sit and rot. Start testing for ammonia, nitrites and nitrates. You'll see spikes ammonia and nitrites, then finally nitrates.
You don't need to do water changes at this point just keep testing. The cycle period could take weeks but some have cycled shorter then that.
Speaking from personal experience I never saw nitrites. I don't know why I just never did.
How much live rock are you using? That will help the cycle along. How much live sand? What size tank?
