Correct, However I would like to add that in larger volume systems, small amounts of rock, if purchased as "cured" from a local source, kept moist during transport, and transported directly from one tank to the other, can be added to the system with little chance of a problem.
I would still recommend a short quarantine period in a small tank so that you can attempt to locate and identify any hitchhikers before the rock is introduced into the system. Polyclad Flatworms, Gorilla Crabs, Mantis Shrimp, and other nasty hitchhikers are far easier removed from a 10 gallon tank with 1 or 2 rocks in it, then from a 75 gallon with 150 lbs of rock in it.
