Live rock is either cured or uncured when purchased but by the time you get it home both types will have die-off on it. SkiFletch was just pointing out that it's good practice to place newly acquired live rock in a bucket until the die-off and associated Ammonia spike has cleared before placing in the main tank to avoid spiking the tank. The more cured the rock, the less the die-off and the quicker it can be placed in the main tank. This is not really an issue in larger tanks but it certainly has to be considered with a Nano.
