Unfortunately running the tank empty does nothing to cycle it and the quick start bacteria will have died as there is no ammonia source to feed them. Your water will test fine at the moment because it's just a tank of tap water, but if you add fish ammonia and nitrite will build up and harm the fish. Please read the article I linked to above - you need to cycle the tank with ammonia to simulate fish waste.
