Chemicals for Black Tank

First time camping with my Fifth Wheel. What chemicals should I put in my black tank to break down the solids? Thanks in advance!

  • You can do a test at home to see what water does. Don't flush for an hour or so and see what happens.
  • Due to the high temps of where I live, I use Pine Sol for odors. About a pint per black tank fill. That's all.

    Works best for us to keep odor down. Keystone put the black tank vent right next to the ceiling vent.
  • Water.

    They're holding tanks and stuff isn't held long enough to break down any farther than what water can do
  • I used to use chemicals until I found out about the GEO method. Thats all I use now. (click on 2oldman's link)
