If it is porous and has holes and whatnot, it will be just fine, all you have to do is wait. Just make sure you add livestock slowly to your tank (1 fish at a time preferably) to build up the necessary bacteria levels for your bioload, and not cause a re-cycle.
If you cycle another tank in the future, make sure there is sufficient die off for a good cycle. (ie, a piece of raw shrimp)
