To much chemical

[Russellvh]

If I’m going to be driving several days I was thinking about doubling the chemicals in my black tank for a good cleaning due to the movement. Would the extra chemicals do any harm or would I just be waisting the extra chemicals?

I'd say the normal dose of chemical would be best. Chemicals are used to help neutralize any odor.

Cleaning is best done by high-pressure washing or the power wash if the feature is available in the tank.

On my last RV it didn't have a black tank flush so I would fill it about half way full of water and throw in about a half cup of powder washing detergent. Then empty my black tank at the campground before setting up. Did that for eight years and never had a problem.

A better solution, when at a campsite that has sewer connections, keep the black tank and grey tank valves closed until one is ready to dump. Perhaps once a day or every other day if needed.

By leaving them open all of the time, the liquids will discharge continually, leaving the solids behind.
