The cup of Tide in the tank 1/2 full and a couple bags of ice will do a good job cleaning the tank as you move to a new campground.
For routine maint, I try to wait at least 5-6 days or more before I dump the black tank. It will get a much better dumpout that way. You can always hook up the black water flush and fill the tank if you need to dump sooner.
Use a clear fitting on the hookup to see when it runs clear and clean after flushing. Some folks swear by No chemicals, we always use them. So your choice. We have no odor (unless the tank is realy full!, and the exhaust fan is on when you flush!) ha
The sensors are pretty usless!
