You have to remember Live Rock is not always Cured once it leave's the shipper it's no longer live. Pre-cured it bascially the starting structure to become Live so you might have some hitchhiker and might not. You still have to Cure it anyhow for a few weeks for actually adding it to your system. But since your are just starting out it good to cure it while it is cycling.
