Sorry i'm a little clueless
In addition to what thom said, if you're buying cured rock you don't need to cycle it. If you are adding rock to a tank that's already cycled, then you want to add only cured rock - if you don't, you'll probably end up with another cycle. However, the cured rock you add doesn't have to be bought as "cured" - you can buy uncured rock and cure it yourself (basically cycle it yourself) in a separate Rubbermaid tub with saltwater, heater, and a powerhead.
Also... cured rock will normally be considerably more expensive than uncured rock.
