Have you been adding anything to the tank? Any food or anything? If there is no die off of the live rock but there's also nothing else in the tank to produce ammonia you won't get any reading of anything. I would ghost feed the tank for a week as if you had one or two fish in there and test again. If all levels remain zero, then I would say you've either skipped your cycle or had a small one, BUT you still have enough bacteria to deal with any waste produced by live stock so you'd be safe to add a clean up crew..
