Do you use holding tank chemicals?

When I first started out, I use to put holding tank chemicals in after each dump. Then about a year or so ago, I decided to see what would happen if I didn't use any and I found no difference in odor.

Since I'm fulltiming and I'm not storing the trailer between usage may help(not sitting idle for a few weeks at a time). I also use my black water tank flush each time I dump.

Just wondering how you all handle this????

That's how it should work. you shouldn't need anything if everything's vented properly. maybe some of that enzymatic stuff that helps move the process of disolving things along....toxic chems used to cover up smells only pollute. What goes into that tank is the world's most biodegradable substance, if you just let it be.

Didn't you know? We Airstreamers don't have to use black tank chemicals, because .... ours don't stink!

I no longer use anything when the trailer is in use. If I happen touse the facilities when it is in the storage yard, I drop in a "Potty-Toddy-Tab" to aid in decomposition. I have a half-bottle of the tabs left over from the old days when I always used chemicals.

I never have any odor problems.

We do use a deoderizer, (non formeldahyde) if there is something in the tank between uses. Most of the time we have a "clean" tank between trips.

We have never found a need for anything in the grey water tank. For a weekend trip, we use nothing in the black either. For a longer stay, I do add a little Rid-X. Seems to work great.

no reason for chemicals in either the black or gray tanks if properly maintained.

for some ideas, tips, and links.

We normally have used an additive (environmently friendly) in our tank. As a matter of fact after dumping the tank prior to heading for home we usually add another treatment and add a gallon or so of water.

This year for the first time we started skipping that final step and found that we were getting nats growing a colony in the tank. When we would take the trailer out of storage the first few uses of the toilet found nats coming out when we flushed the toilet.

So we went back to adding the holding tank stuff before we departed for home. No nats on next use. It seems like the water in the tank with some chemical added keeps the bugs out.

Holding Tank Treatment

Our Safari is our first RV and when we received our dealer walk-through and orientation, we were given a complimentary trailer starter kit, which included some holding tank treatment samples. We were told that it is a good idea to add the treatment with a gallon of water to each tank. We then picked up a 68-oz. jug of Odorlos (No formaldehyde) from Campland and have been using it after each dump of the tanks (black and gray).

It seems to be working just fine. We have never had any trouble with odors. (rluhr may be on to something… see his note above). And we liked the idea that this product breaks down waste/tissue and lubricates valves.

We now have run out of the stuff and were looking for this product locally when we realized that there were a number of products on the local shelves at Wal-Mart and our local RV store (but not Odorlos). I also just became aware of the importance to the environment to use a non-formaldehyde treatment product.

So I thought… well that’s typical… every aspect of this trailer has required some research so that I had a chance to "get-it-right" the first time. While using the search engine here, I noticed that there were some who were having a problem with sewer odors. For example, TBRich:
And I thought it was curious that he did not say if he used holding tank treatments.

And then I found this thread… and I was amazed that most did not put treatments in their tanks!

But I was also equally amazed that the last post here was four years ago.
So now I think its about time to "bump the thread" and ask:

Do you use holding tank chemicals, treatments?

And, if so, why and what do you use?

And if not, why?

maybe that's because there is a black tank 'full' of annual threads on this topic...

with many details, so check the 'poop' sheets...

yes 'nothing' works, enzymes work, bacteria+enzymes work...

soapy water transferred to the black tank mucks up the process.

cleaning with chlorine mucks up the process.

parked units may need digestives, those trailers that are on the 'go' usually don't.

the 2-3 top tier products are still top tier...

not many new or different products, virtually NO ONE uses formaldehyde products anymore....

i've not seen formaldehyde products on a rv vendor shelf in years...

the 'f' issue was big 20 years ago but still gets playing time.

and the truth is many of the 'non-f' products have other agents that are equally bad.

the old sailing adage of 'don't put anything IN the toilet that you haven't eaten first' still applies.

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.

I have used chemicals for 8 years and no odors. I also completely rinse out both tanks then add some water and chemicals before leaving for home where the rig would be sitting until the next trip.
