HAPPY CAMPERS RV Holding Tank Treatment - 18 Treatments

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

I like that product

I usually flush my black tank 3 to 4 times with the other products I usually use. I have noticed that it is only taking 2 flushes until the water runs clear. It took about three cycles to get to this point but I am very happy with the results. I am very satisfied with this product and I will be buying Happy Camper again.

I’ve been using the stuff in the trailer for years. We bought a trailer that had its black tank built up. We emptied and refill the tank every three days for a week and it cleared out all the build up. Simply the best!

First of all, we live in Texas where it gets really hot. All of the tank additives we have used before have not worked on the odor. We throw our toilet paper in the garbage and only flush the “natural stuff.” In 100+ degree weather, our tanks have always gotten horrible smelling within 3 days of dumping no matter what we used. But, since we started using Happy Camper, we are happy campers. We can go a week to 10 days between dumping without odor running us out! And, there is minimal odor while dumping! We are so happy! We will be putting Happy Camper on scheduled delivery!

Just the right size container

Works great
