Black water chemicals
With all of the choices on the market, some even opting to not use any at all, what do you use and why?

It's a holding tank not a septic tank so you don't need to add anything to it. If you have odor problems then you have a leak. I live in my travel trailer out of town 3 nights a week and I don't use anything for the tank other than water and I've never had any odors either unless I forget and flush while the vent fan is running.
