Cycling

[CrayolaViolence]

Even "live rock" and "live sand" will have some die off from transportation,etc....
But yes starting with stuff that already has sufficient "bacteria" on it and not much dead particulates you will/may have a very short cycle if any..
In general a tank is "cycled" once its consuming any ammonia through to nitrate in a very short time and can do so very quickly.. Before it has a chance to harm any inhabitants/build to "dangerous" levels..

I'm not talking about rock that has to travel. I'm talking about rock and sand from a tank that's already up and running. Live rock that's traveled would need to cure, not just cycle and that's a whole other game.
