I am not understanding the concept I guess, .
Your previous rock still bacteria existing in the deepest and smallest pores of it.
The process goes like this
The dead matter on the rock falls off into the water producing ammonia, nitrates phosphates and a whole lot of other organics.
This is called Curing
The bacteria come alive in the rock and work on the ammonia--to do this they must cycle their numbers to match the bioload or ammount of ammonia that comes off the dead rock. This is called CYCLING
As the rock cures the amount of biomatter eventually decreases, the bacteria are able to catch up with it and reduce it to nitrates.
Then a second strain of anerobic bacteria called anoxic bacteria step up to the plate and work on reducing the nitrates
One method of cycling your tank is to monitor this process by measuring the ammonia and the nitrates. You should see an ammonia spike then a decrease to zero and then a nitrate spike and a decrease to zero.
At this point you know your bacteria has cycled in numbers enough to be able to start to add creatures to your tank
This process can take anywhere between 3-5 weeks depending on how much dead matter was on the rock originally.
Reefers adivise you still to go slowly after the orginal cycling of bacteria as their numbers drop off so they are in equilibirum with the biomass they are handling
Curing of live rock happens once(hopefully) in your display tank however cycling of bacteria is a life long process. Everytime you increase the biomass in your tank you must allow time for the bacteria to cycle their numbers to take care of it
