Yep, nobody wants to be stuck behind a fellow rv'er that wants their black as clean as their fresh tank. I figure every few trips when I dump and the place is deserted I backflush for 3-4 mins and then im on my way. The idea of a few gallons of fresh water in an empty black tank is SMART. Use whatever chemicals floats your boat but as mentioned its a storage tank not a septic system. Ive had great luck with my sensors adding water softener to "grease" the sides of the holding tank.
