During season usage... After emptying I squirt some dawn dish detergent and about a gallon of water. That is it. Last dump of the season I leave it (black tank) empty after a thorough rinse and clean! I do not use any other treatments!
Or you can leave the valve closed until tank is full and then dump!
In our trailer, that would work on all of the tanks except the galley tank. The valve for it, in Keystone's infinite wisdom, is under the slide, just aft of the rear axle. When set up for camping, the only way to access that valve is to crawl under the slide, negotiate the rear ram on the slide and then shinny under the trailer to reach the valve. While it's "OK" in some parks, to use the words from an old Ray Stephens song, unless you "crawl on your belly like a reptile", you ain't getting to that valve.
It's much easier to leave the galley valve open, use that "Chinese finger" hose holder to maintain the slope and let the end dangle and create a P trap to stop the gasses from migrating up the hose.

You sure have a good point John, I guess there are always circumstances that can make a difference on the best practices.

We have a washing machine going into the bath grey tank along with the shower & lavatory, so I have 2 choices, #1 leave it open which is what I do or #2 go out & pull the handle daily, which ain't happenin'. When laying out your sewer hose it takes about a millisecond to drop a sag in it then leave the valve open. Now if your just laying the hose out like a big snake on the ground it's hard to leave sag in it.

Agree. We've used both of these products in the gray and black tanks; no smells and our sensors now work. Also, we use the wand a couple times a years to get all the tanks extra clean. View their web site and watch the video's http://tanktechsrx.com/https://uniquemm.com/
We always put another packet in, with about 4 gallons of water, after the dumping is done. Since we have done that method, never had any issues with odors. Sometimes its only 2 gallons, but I kinda play that on the weather (to combat evaporation).
