HAPPY CAMPERS RV Holding Tank Treatment - 130 Treatments

We tried every liquid treatment under the sun and not one of them worked. One single treatment of this and all odors were completely gone! Follow the directions on amount needed and you will be amazed at how quickly your rig will be odor free.

We have been full timing at the Gulf Coast of Texas since May and not once have we had any odor issue. It breaks down the contents better than most. Extremely pleased and we would not use anything else.

If your black tank in the rv is smelling bad this product will solve the problem

Use it consistently in RV and tell all other RVers we use it

We are new trailer owners and happened upon Happy Campers for waste tank treatment on Amazon. How lucky were we! I was looking for a non liquid as I was trying to keep down weight. This is the best I tried! And the added benefit is can be used in Grey and Black tanks! Winner Winner! Never smelled any odors at all. Great Product!

I bought this for the quantity and the great reviews. We used it for the first time. A month ago now. I mixed per the directions in a gallon jug and put it in before we hit the road. It seemed to work fine. After two days of camping it started to smell. I added another dose and the smell went away almost immediately. I think next time I will up the dose. I believe it works well and the large quantity should last use a few years . I would recommend using more then the directions say.

It is a all in one product good for every tank

I purchased this product after purchasing many other holding tank treatments over the years and this one is the best by far. I have tried for years to clear the tanks so that my gauges would say 0% full after being dumped. At the most after using other products my tank gauge wouldnt read any less than 33% when they were completely empty. I emptied the gray and black tanks, mixed a scoop of this product with a gallon of water for each holding tank. I let it sit overnight and the next day I opened the tanks one by one, turned the flushing system on and watched thru the clear sewer elbow a huge pile of gunk pour out for a minute or so then nothing but clean water proceeded. I have never had the tanks clear that quickly. This stuff is amazing, I will be putting a scoop in after each dump for sure. Im so glad I took a chance because of the other fantastic reviews from other reviewers and I purchased the huge bucket. This product deserves a 10 if it was possible.

great product. have used for years. quick ship, good price

I was very excited for this product to arrive as I have read many reviews and it’s highly recommended in several FB RV groups but it arrived in a dented up package which cracked the container and spilled a lot of the product out of the box before even opening it.
