HAPPY CAMPERS RV Holding Tank Treatment - 18 Treatments

I’ve been using this for 3 years as I travel about 6 months a year. Easy to use and never had any issues with smells

I researched for over a year to find a black tank treatment for our RV. We empty regularly and flush it out but there was always that yucky black tank smell like rotten onions. I was hesitant to try this one due to some saying it landed like concrete in their tanks. Decided I tried everything else so got it. FOLLOW THE DIRECTIONS PEOPLE! If you mix it up like it says, and you do have to literally dissolve it and stir it, it works WONDERFULLY! Just make sure to dissolve it, we use a separate bucket to mix it and then pour it in with 3+gallons of water. No smell whatsoever! Have used for over 2 years now!

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!

Out of all the rv deodorizer for our black thank this product keeps Oder down the best , you definitely need to give it a try

Great delivery time. Very happy with order.

This works great! Best I have ever used!

We discovered this product in a small RV supply store 8 years ago. Until then we had lingering odors no matter what I did. After using it, nothing, ever again. At that time I had to track down the manufacturer to order more. It was never in Camping World! So happy to see it on Amazon!

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

I have been trying for so very long to find something to take the septic smell away from our rig. This product has worked to a point. Once our tanks get to about 67% the smell begins all over every time you flush. I have bought it a second time to see if it just is going to take some time. Our sensors continue to be clogged and the only way we’ve been able to clear the sensors is to run the cleaner wand after every dump. We are in South central Florida for now and going back to Indiana soon. This is now our home on wheels and I am really hoping this starts to work. I’ve read so many testimonies that rave about this product and I have quite a few friends who use this and swear by it.

Having used many brands for eliminating odor and cleaning sensors, this is the best I have used. Not as convenient as dropping a pod in the toilet, but much more effective. All of my level sensors are now working, after years of not having worked - a major improvement. I dont get the occasional whiff of a smell I used to get with other brands. I have a 09 DP bought used 6 years ago when no sensor worked.
