Lots of water and the black tank.
Blank tank threads always get a lot of responses and one of the most common responses is "use a lot of water." I see it over and over, but what does using a lot of water really do? Or is it just one o...

"Lots of water" really is relative. It is relative to the size of your black tank. My black tank is just ten gallons in my B. I start after I dump the tank by adding a gallon of water to the tank. I have a permanent macerator so I can't use a tornado to flush the tank. I have a wand but don't find it any more effective than filling the tank with clean water and dumping that. While in use, the black tank gets the water that goes down with each flush. Were I to fill the bowl after each use and flush again, I would fill the tank in five or six uses. Before I dump the black tank, if it is not full already, I add water down the toilet until it comes up into the toilet indicating a full tank (black tank sensors have not read correctly since I got it). I tried the GEO Method for a year and a half and saw no difference from using the blue/green stuff. So for me, lots of water is a gallon to start (1/10th tank capacity), and that seems to have worked well. In the winter when I winterize, I put a gallon of antifreeze down into the black tank to take the place of the water that was in there the rest of the year.
