Not true, especially if it's a popular saltwater store or a store that does not stock a crud load of it. Which means the live rock is not in the store long enough to cure.

What happens when they get a shipment....they add it to their tank (the top of the tank) and then you walk in an hour later and buy it. That's not cured live rock.
