Black & Grey tank chemicals - What do you use ?
I'm using Calgon & deorderizer in the black tank now. What else can I do ?

We don't use anything and haven't for 2 years. We use the black tank rinse at every opportunity. No smells at all. Our trailer before this had a black tank rinse also but e hardly used it and had more some stinky situations. I'm a firm believer in the rinse cycle.
