I would keep a few gallons of water in the black tank with some treatment "stuff" to keep any remaining solids wet and prevent them from sticking to the tank. and I would not recommend using any treatment with formaldehyde in it, if they even sell any anymore, but a little bit of that certainly won't "kill" a septic tank.
and you really don't have to 'break down" anything, it is a holding tank, not a septic tank.

Just wanted to make sure that after you dump, you make sure to rinse a few times the black tank, either with a wand or some kind of flush system. Then add a little water and chemical. Good luck.
I'll give you our "dumping process" it has worked well for years and we have zero problems.
- Go to dump station and hook up clear elbow and sewer hose to camper dump valve. **the clear elbow is great so you can "see" when the tanks are clean and empty**
- Pull black dump handle
- Pull gray dump handle
- Wife inside camper now starts filling buckets of water from bath tub (we always make sure to leave enough water in our tank for this) and flushes clean water down toilet
- Keep looking at clear elbow to see when the water is clean (from wife flushing into toilet)
- Once water is clean (usually only two buckets into toilet), close black dump valve.
- Wife then dumps one final bucket of water/pine sol mix into toilet. This is what stays in there until we use in next. Never any smell!!!
Also, she usually keeps the water running in the tub so the gray tank gets rinsed too.
We have been doing this same procedure for years and it works well. I will always make sure we have enough water in our tank to do this and if we don't, I'll fill it a bit prior to dumping.

Thank you for putting it in steps for us. This weekend will be our first time doing the whole process.
The GEO method can be a little daunting for a newbie. Swing by your local camping supply, Walmart, whatever, and pickup some Odorlos Holding Tank Treatment. Follow the directions on the bottle or tub (depending if you prefer liquid or powder) and enjoy your new rig!
Well, I'm one of the guys you don't want to be behind at the dump station...
First, open & dump black tank, close valve.
Open & dump grey while filling black tank with water. I use a hose thru a window. My new trailer has a flush so I guess it'll be diferent now.
When black tank is full, close grey valve and open black. Then fill grey tank either by putting hose in tub or kitchen sink. Once full, close black and open grey. They both should be rinsed clean by now. I've never left any water in the tanks. A couple gallons would evaperate quickly anyway. Most of the time I leave the valves open & cap off.
