HAPPY CAMPERS RV Holding Tank Treatment - 18 Treatments

While it doesn’t always get rid of poo smell. It has improved the smell in our camper remarkably well. Works better than anything else I’ve tried so far.

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,

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

Ot works as advertised! Was using pods for years and recently changed to this!

This was recommended by friends that are full time campers. We go out for a month at a time and please how easy our black water tank cleans up.

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”

This stuff gets excellent reviews and why I bought it. However, I’m not sure my results were that exciting. I was in FL where it hit 90s every day, so possibly there’s nothing on the market that will do well in high heat. But I found tank still stunk after 4 days and found myself flushing / rinsing the same interval with or without (this includes the aggressive Calgon / Dawn / pine-sol repeated flushing) many people do. Results are still up in the air for me.

I’ve used this for years and it is very effective and simple to use. No chemical smell just white granular you scoop and put directly into black tank.

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
