Its possible there won't be any spikes. Since setting up my tank i haven't had one. My water has been almost perfect since the beginning. Then again my live rock was pretty well cured, i did the smell test on it. You could get some cleaners in there, ie snails, hermits, and shrimp and they will help with cleaning up the rock untill your levels stabilize. <p> Just remember don't be impatient and a good rule of thumb is to just wait 4 weeks with initial setup....
