HAPPY CAMPERS RV Holding Tank Treatment - 130 Treatments

The only brand we will use.

Tank treatment works well and as advertised.

Great product

Ive tried other additives in the form of both liquid and single pouch style but came back to Happy Camper because it works the best

Happy Camper is wonderful for keeping RV tanks clean.

Hard to get excited about an enzymatic agent one adds to ones travel trailer black water tank. But - This stuff is environmentally friendly, very easy to use - and does what its supposed to do. As a few other reviewers have noted, weve found that one must add double the amount of product recommended by the manufacturer to the tank if ones goal is to have a totally odor-free experience upon emptying the tank. Weve found that the recommended amount DOES break down the organic matter in the tank, however, and greatly reduces the odor. As were not royalty, we manage happily with the recommended measure. :)

This is our third purchase of this product. Its the best that we have found to deal with odor from the black tank on our 5th wheel trailer. Definitely recommend this product.

UPDATE: Ive been using this stuff now for more than 18 months (about six months on the road) and its working still great. My sensors never did recover fully (see mention of sensors below), but we experience no odor whatsoever. I think I do use more than the recommended dosage. I use about 1/3 cup as an initial dose if we will be in one location for a week or more. I also add another modest dose (about 1/4 cup) at the end of a week if we will not be dumping for another few days. Weve now gone as long as 12 days on the two doses. ORIGINAL POST: This stuff works. Ive been using it for three months, 90% dry camping and boondocking with up to 11 days between trips to a dump station. This has been a fairly severe test. Also, my tank level lights which have been useless for a couple of years (always reading 2/3 or full) are starting to come back to life. Recently I had to replace my RV toilet while the black tank was 80% full with 8 days of sewage in it. While doing the change I also had to fish an object (long story) out of the 3.5 inch; pipe from the toilet down to the tank (using a flexible extension camera from Harbor Freight and a home made noose). There are two 45s in this pipe! The object was stuck at the bottom and causing a frequent clog. It took more than two hours to successfully get ahold of it and bring it up. I (actually, we) did this after the old toilet was removed and before installing the new one. I did add a second dose of this digester stuff a day before this undertaking and Im sure that helped. There was virtually no oder during this operation. DW was assisting and never complained of an oder (she would have had there been one!). I probably use a bit more of the treatment than necessary, but at this price thats acceptable. Its looking like Ill get at least 5 years from the tub (4 months per year in the RV). Its far cheaper than the pellet things which run $1 or more each (and I often used two at a time trying to make them effective). Im sold on this product ... no more oder complaints from the DW. Enough said.

We have used this product for several years and just love it. The packaging wasnt the best in the world. When received the item the box was tore completely apart.

Works very well. Easy to use.
