Default Newbie question about blackwater tank

Recently bought a 1999 RT Popular. There are slot of different products for black water tank treatment. I tried the stuff left in the cabinet by the previous owner and the "deodorizer" smelled worse than the "odor" it was supposed to control.I like some recommendations and experiences from more experienced owners.
Thanks, Ed

Default No Particular Recommendation

I've used Camco RV Toilet Treatment and Thetford Aqua Kem. Both work well, in my opinion.

Why do you think you need to use chemicals in your tank?

A properly-functioning plumbing system needs no chemicals. All that junk is palliative for covering up a problem. If you have order, find and fix the leak.

Although I agree with avanti, I have always used a product by Happy Camper that doesn't have an odor and uses a bacterial base. I've lately wondered if many of the vault toilets in campgrounds that used to smell so much are now using a similar chemical. Their smell is much better overall.

I've been using Odorlos and it seems to work great. It is suppossed to help break waste down faster as well as neutralizing odors. One of the old timers on this forum suggested it.
Not having a p-trap in RV toilets means that sewage gas is going to escape whenever the flap is opened. A roof vent might help but I don't know I have a side vent so I installed a low power (SOG) inline vent fan.

my favorite black tank treatment is a half cup of dishwashing soap (like Dawn, not the stuff for automatic machines), and a half cup of Borax powder.

cheap, and works well!

Inexperienced here with a question. What level do you have in the black tank when you pour the ingredients in?

Welcome to the forum SnSC!

Best to never let your black tank run completely dry. After you dump it, add whatever your ingredients and about a half gallon of water.

If you keep your tank clean it doesn't stink. I regularly clean mine out. Dishwasher detergent and a couple bags of ice with a few gallons of water then go for a drive...

When you use it, clean it out asap. I do my best not to go #2 in my rig if I can help it though.

I always found chemicals to be worse than any smells and they seem to soak into the walls/fabrics in an RV...

Default Downy fabric softener; one cup

Downy fabric softener; one cup: coats the tank to prevent stickiness. Best benefit; smells great. Got this tip from this forum 2 years ago!

I didn't know that you're supposed to dry out you black tank and set it in the sun for a few hours before you clean it. WOW

Same here, except I use Dawn with Calgon. Works great, and yes I clean the sh** out of it about every 3rd dump.
