Steve/Folks:
OK, I think I got it! It's true that the little Aqua-Chem, etc. bottles are more practical (and cheaper) that one gallon of chlorine, so for normal flush use (not "sanitize"!) and odor control that will be more suitable. Perhaps I misunderstood the RV technician about the chlorine stuff.
Thanks to all for the invaluable advice!

You add chemicals to the black tank to control odor and help break down solids--not to "sanitize"--at least the way that most RVers use that term. Sanitize usually refers to the drinking water system where humans are actually going to consume the water. That needs to be sanitized periodically with a clorox solution to kill the germs, but thats only the fresh water tank. You dont need to sanitize the gray or black water system--just flush it out periodically. Some people dont even use any chemicals at all in the black water tank and this may be fine, especially when its cooler weather and you flush each time with plenty of water.

The cheapest solution is what a lot of us out here use - nothing except water.
The septic system is sealed except for the roof vent/vents and if you get an odor then there is something wrong with the system that needs to be corrected.

I have a friend who uses clorox during hunting season in his tank. I have read on this forum that this is not a good idea. the two ways that are and make sense is the GEO method and using black tank chemicals. I have used just about every thing on the market in my black tank over the many years I've been camping. I heard about a chemical called Happy Camper. This stuff works, bar none. I bought mine on the Internet. I bought the big box and gave some to my kids in coffee cans. It is more than I will use in my life time. I have a quickie flush in my tank and with that and the happy camper, I have a clean tank and a non smelling tank.

I recently bought the Happy Camper stuff and had no tank odor during a 4-day, 95 degree camping stay.
Here is their website with ordering instructions:

Uh.... actually, most of us have found that you do NOT want to turn on the fan on your roof vent when opening/flushing the toilet. Because the fan can pull the odors from the tank into the bathroom!

What works best in the black tank is biological action .. The very last thing you want to do is sanitize it You want bacteria to break down the solids so they flush out.. The best thing to use if dumping often is WATER
If you are going to be sitting w/o dumping for an extended period, Then a good BIOLOGICAL such as Odorlo's or waste dig ester
DO not use chemicals at all

Just as someone mentioned above, the Geo Method is a great and very inexpensive way of taking care of your tank. But do not use an entire gallon. Bleach isn't used to sanitize a black tank, it is used in combination with laundry detergent to keep the odor down.

Actually, it IS a septic tank. Use the properly designated tank additives so that the biological process can continue. Bleach, or most any other "household" cleaners are a no-no.
There are many threads on this topic here.

So that you can create a vacuum where you are, thus sucking the odors directly into your face? No, thanks.

All you need is some natural bacteria which can be put in there with Ridex or some other packets. Don't put Chlorine down your black tank. It eats the seals and destroys the natural bacteria eating your solids.
Use plenty of water, flush out the tank regularly and don't dump unless you have 75% of your tank full.
You should never have a problem.
