Most organic material will be oxidized by the chromic acid and the chromic acid will be reduced to trivalent chrome. If there is any organic matter in the tank it will probably be charred black mess.

My understanding of hard chrome is poor, however if organics contact hex. chrome. The organic will be cleaved to smaller branches by hex chrome which in turn will be reduced to trivalent chrome. Skim tank and catch the junk floating, then stop the source. High Current Dummy to oxidize the tri chrome back to the nasty six. Double check your vent and go home, by AM back to another day in metal finishing.Jon Quirt

Nothing that will actually interfere with plating. However removing all the caked out muck at the bottom of the tank is quite painful every now and then.
