Just did a really big water change, around 75%.
I'm still having some issues with ammonia, due to the recent crash and my using erythro in the tank. I just set up an AquaClear 20 on the tank, and stuffed it with media from the 20 gallon. Hopefully that will help reestablish my biofilter. I am also using a LOT of Prime, to lock up the ammo that forms between WCs.
