Oh, you left it in for 10 weeks, not 3 days, I misunderstood. And yes, I know about curing rock. However, I still stand by what I said. Curing really is for live rock, not dead dried base rock. You curing the rock is essentially letting what is dead and dying die off and leave the living stuff on the rock. You don't have any dying on it, it's ALL dead. So there's no point trying to save any living stuff on the rock. In addition, like I said, most bacteria or animals that did collect on the rock over the 10 weeks would die when you put it in the tank and crank up the temp by 10 degrees or so. If anything you'd need to cure your "Cured" rock before putting it into your tank.
