[Richard and Rhonda]

The odor control is a fairly simple system that applies voltage to two electrodes in the tank. If you add some salt to the system, the voltage breaks the NaCL down into hypochlorite (bleach). The chlorine kills the stink.

You can see how that works for you.

Or you can use additives of your choice.

What I would not do is use additives and the odor control feature. You could set up a chemical reaction of unknown byproducts by applying electrolysis to the chemicals in the additives.
