HAPPY CAMPERS RV Holding Tank Treatment - 18 Treatments

I like that you can use in toilet, sinks & shower, and not just in the black tank.

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!

Been using this product for over a year. Very satisfied. Little pricey but it works.

No scent! Works very well and is easy to use

Finally, no more smell in the bathroom!!

Awesome product

I’ve been using Happy Camper for 4 years. Never had a “smell” issue. This stuff is the Best!!

was having black tank smell in bathroom and now it is not there at all done with that blue stuff that didnt work this stuff is the best

this works well for deodorizing your tank and it does not add any chemicals smells to the tank. We have been using it for a few years now and are very happy with it,

Use in my rv, its the best!
