I'd think it would need to be completely cured again. In your place,
I would place it in a large tub or tank with some kind of circulation
for a couple weeks. Perhaps even do a couple small water changes.
Once the ammonia starts to disappear, buy a couple pounds of new LR
and add it to the tub. Wait until water params are acceptable. Place
in new tank.
