Do what Smite suggested above and don't use fish to cycle a tank, it's kinda cruel, especially if there's ammonia present. This is an archaic method that should just go away, especially now that we can add the ammonia ourselves and we don't have to deal with fish we don't want later on. With dry rock, add all the bacteria you can (they're all pretty much the same) and I would add some PNS substrate sauce, as this has PO4 added to feed the bacteria and to get things going. I also phantom feed the tank as if there's a couple small fish in there during the cycle time, which helps to fuel the bacterial growth and feed any pods or worms that may have been added. I honestly would look for some established live rock and add piece or two if you can? Unique corals usually has some Australian or Solomon Island rock for sale. It's not cheap, but it's worth every penny in the long run.
