Once a year I get me a $1 bottle of Pine-Sol cleaner and a 20lb bag of ice. Put the Pine-sol in the black tank, fill with about 3-5 gal of water and dump in the ice. Then I take off on a trip that I know will be about 2-3 hours driving time, and I try to "slosh" the black tank during turns. For me, that keeps my black tank clean and the indicator pretty much accurate.
