It might...but why use both?
Much as I'd love sell all the K.O. I can, there's no point in using both K.O. and Odorlos if Odorlos works. It's a complete treatment that utilizes the same aerobic sewage management principles that K.O. does, only doesn't depend on outside oxygen. The difference between the two is that the "shot" of oxygen provided by the nitrogen is finite, so more must be added--especially in hot weather when bacteria multiply fastest--periodically to replace it...whereas the bacteria in K.O. multiply just as fast as the bacteria in sewage in all temperatures, but need an outside source of oxygen to prevent odor. Combining them would only be a "belt and suspenders" approach. Use the ONE product that works best for you.
