Black Tank Treatment

[Cal and Pamela]

I would like to know what you all use to treat the waste in the black tank. I’m using a powder treatment but thought about switching to a liquid and eco friendly, Bio-Kleen Kleen Waste is a brand I’m looking at… what do you guys use?

We have used Pure Power Waste Digester and Odor Eliminator for 5 years (liquid)....works great....no odors whatsoever! 2 ounces treats 40 gallons.

Century makes a Waste, paper and grease digester that we have used , but quite infrequently. With a good tank cleaning once a month we avoid any buildup or odor.
