Call it a clearing tank. Very few beers undergo secondary fermentation and no bubbles is quite the norm. In fact, if you do get fermentation in the clearing tank, you probably racked too early.
Also, unlike wine, never top off brews except at the beginning of the fermentation.
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
