HAPPY CAMPERS RV Holding Tank Treatment - 130 Treatments

This is the only product we trust.

Great product. Have been using it for years, and it works as described.

We live in our 5th wheel and this is the best stuff Ive found. I use twice the amount instructions tell to use, but it is because it works so much better when I do that in regards to odor, etc.

So the next time you launch a bomb in your RVs black tank, you should feel comfortable knowing that this magic stuff will go to work right away to dissolve the solids and eliminate the, er, stink. Not a substitute for the Fantastic Vent above the toilet, but it sure does knock down odors for good that might find their way out of your tank. I have 48-gallon tanks and I put 2 scoops in the black and 1 scoop in the grays. SO glad they released this bigger size.

Happy camper is a great product , it works well and I will order it again.

We bought Happy Camper in 2013 (biggest size), lived in our 5th wheel for 3 months, and yearly since for short trips. Never had an odor problem, lasts forever, and takes up almost no space in the RV what more can you ask for? Just now reordering.

I have been using this product for the last two years in an RV and have no complaints. By far one of the best products on the market for your holding tanks. It is difficult to find in camping stores, so Ive always purchased it online form either Amazon or the manufactures website. If you can store the large container, this is the best price around, especially since the shipping was free.

This product works great.

Works good, my nose is a happy camper. The bulk size makes this a very affordable. Got tired of running to the store burning gas and paying lots more for the smaller sizes.

Easy to use seems to work fine although for the few weeks it was over 90 degrees we did get some foul odor....
