The cycle will probably take you roughly 6-8 weeks, depending on the amount of dead stuff in the dry rock and the amount of dead life on the live rock that didn't survive shipping and handling by the time it gets back into saltwater. If the rock is really clean, it might be less than six weeks.
Live rock is generally a piece of reef rock (ancient dead corals) that is pulled directly from wild reefs or culture facilities. It is then boxed and immediately shipped to your local fish store or a distributor. Live rock provides structure for aquascaping and biological filtration in your aquarium. More often than not, live rock rock is still moist from being shipped right after it is collected. The reason for such quick shipment is to avoid the die off of beneficial bacteria and organisms that use the live rock as a host.
