Thats alot better, although you could do with dropping the nitrates a bit, they aren't going to kill the fish at those levels though. Continue monitoring the nitrite levels just to make sure they don't jump again. If they do spike, do a water change. Hopefully now the nitrites are gone, the clown will start acting a bit more normaly (whatever normal is for a clown). Keep monitoring. If he's eating and active, all should be fine.
