Do you put in black tank treatment pod prior to storage?

During camping season, after I dump tanks, I add treatment to the black tank and add several gallons of water. It helps if there is an odor issue and is ready for the next trip. Perhaps I over do it with the treatment. Find one whose "perfume" you prefer/tolerate.
For winter, I also add treatment, and a couple gallons of water, AND RV anti-freeze. I haven't had a problem in several years of this process.

Cheers,
