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

For those that "claim" a perfectly working black tank will never smell, have genetically altered poop. A perfectly working black tank has to vent somewhere, if working perfectly it will vent outside through the vent stack. For those of us that sit outside while camping, if the wind goes the wrong direction it smells. A deodorizer helps with that downwind smell coming from the perfectly working vented black tank.
