For my zeo-vit system when I swap the zeolytes I throttle back the water flow another 75% from it's current rate then slowly increase it again over the course of 2 weeks.  I find that you can't really have too little flow through the reactor but it's VERY easy to have too much.  Dunno if that works the same with ultralith though.
