How much liquid will cover the bottom of my black tank?

Just in general I know tanks are not all the same size but I have a 21' HTT the black tank is 22 gallons. I want to keep some liquid in there sloshing around when I travelling (after dump) how much...

After dumping, I fill up the toilet and flush 3 times. Don't know the amount of water in gallons or pints but I know I've never had any problems with black water tank. Sometimes if I think about it I'll toss some laundry soap or dish soap if going to travel far before I dump again.


X2...except I only do 2 toilet bowls
50 gallon black tank.
