HAPPY CAMPERS RV Holding Tank Treatment - 18 Treatments

Great product

By far the best rv toilet tank treatment I have ever used. And the smell is very nice and lasts.

We tried other products but this one by far ranks the best! Literally no bad smell while using it for weeks, plus when dumping the smell is far not bad at all like the others. Would recommend too anyone with odor issues as it does as it states or money back.

Ive been RVing for years, and this is the best black tank treatment Ive ever used. A scoop into the tank, add some water, and done. No smell, the waste breaks down and is easily dumped when the tank is full. I dont think Ill ever use the blue liquid again!

This product was recommended by a mobile RV repair man, I had tried many other products but never found one that didnt smell awful. I am so happy with this product, easy to use, and no smell. I will never use anything else and recommend it to all RV owners.

Great product for controlling tank orders. Only down side is has to be mixed in container with 1gal of water before adding to tank. Highly recommend for controlling black and gray tank orders.

Awesome product

Good product. No perfumes or strong scent to mask odor, and no tank odor. Only downside is that it must be mixed in a gallon of water before pouring down toilet. Recommended.

I was sceptical reading all of the glowing reviews. Not anymore. As others have stated, what type of wizardry IS this? No more malodorous olfactory offending events occurring right from the very first use. Amazing. I did intentionally buy the smaller size for my first purchase, Ill be buying the larger size and Ill keep transferring product from the larger to the smaller to save space (and still have the factory labelling, directions, warnings, etc.) I decided to keep a 1 gallon jug in with the product (and a small widemouth funnel to facilitate getting the scoopful into the jug) which makes it easy to mix up the partially filled jug, then top it off and shake again. When Im done dumping its a cinch to then pour the solution down the loo to refresh the magic and wizardry. Life is good.

I’m just going to go ahead and give this 10 stars, 5 doesn’t do it justice. We had a horrible smell coming from the black tanks into the camper. After using different treatments and deep cleaning them nothing worked. We were at our wits end. My husband decided to try this and ordered a small jar and the next day after putting it in both toilets, the smell was completely gone. We were amazed. I will definitely keep ordering this and recommending it to everyone we know with a camper. We are now ”happy campers”
