I agree, many of the just plain water folks make quite a stink!

Oxykem packets

Been using Thetford with formaldehyde along with plenty of water for decades. We've never noticed any odor. But we can darn sure tell ya who don't use any holding tank treatment when we're parked next to'em!!!:M

Happy camping!!! See y'all down the road!!!:)

I put 4 gallons of water (or so) in the black tank before each trip- I don't use any chemicals and don't have any odors (yes from the tank!). I have a tank flusher and use it every time I dump the tanks. I have clear section of sewer pipe so I can see when the water is running clear. have been doing this the past few years and it works, the longest we have gone between trips is 4 weeks and still no smells from the tank.

Water........plain and simple.

I like The Geo Method.

The VERY best is lots and lots of water.

Pretty much the rest is up to whatever scent you like...pine forest, lemon mist, raspberry razzle, etc..

There is no BEST additive.
Correct dumping of the black water tank and grey water tanks will give you the trouble free use you seek.

Chemicals will just control odors and MAY minimally provide some breakdown of solids.

All I use is Bromine in the tank to control odors and have yet to have a problem

Happy Camper is a great product. I have used just about all the different stuff to pour down the toilet and this stuff is the best bar none

Someone will probably tell you to use the search function. I had a question about this last month, searched for "black tank cleaning" and ended up with a few hours' reading.

I decided on trying the Geo method (you'll find it during the search) and it worked great.

Happy hunting.
