Black Tank Treatment - taken off the market . . . .

Another for water only. We travel 5 months over the winter and only use water. The toilet is used as we would at home. Toilet paper - the regular kind.
No add in chemical will do any breakdown during the intervals in between dumps. I always add LOTS of water before dumping. When at a full hookup I'll take the opportunity to fill completely and dump a couple of times. No odour problem.
