    • It REALLY works!!!
Just retired. So we’ve been doing a lot of camping this summer. We’ve used a product that are orange pouches that you drop into the black tank. Problem was an odor that crept into the bathroom within a couple of days. Didn’t smell good. So we found this product and used it this past week while camping and NO ODOR! It does exactly what it says it will do! ... show more

    • Does not work for Porta Potti
Initially i bought happy campers treatment to be used for my thetford porta potti 365. i only use the porta potti for no. 1 and only needed to be emptied around once a week. previously i use walex porta pak so i tried switching to happy campers treatment because everybody was singing praises about this product but unfortunately for me, happy campers treatment is unable to cover the odor because i could always smell urine whenever i use the porta potti and by the end of the week where i empty the waste tank, it reeks horribly :( i am not sure if my dosage is not enough or is it because the previous usage of walex porta pak has some residues remain that lower the effectiveness of happy campers but the waste tank smell horrible at the end of the week when i empty it. i tried cleaning the tank and give another shot but the smell is still bad and emptying it at the end of the week is horrible. after reading that happy campers treatment requires oxygen and does not do well in airtight environment like a porta potti, i guess i will stick back to walex porta pak for my waste tank. so i started using happy campers treatment for my grey tank instead and to my surprise, it works amazingly well! usually my grey tank will smell bad at the end of the week but ever since using happy campers treatment, the grey tank has no smell at all. it's a miracle and emptying my grey tank is a breeze now. ... show more

    • No More Stink
Didn't want to write a review until I had used it more than once. I live full time in a RV so I deal with the black tank on a weekly basis. I have tried all of the other items from the rv section that promise to make it smell like orange or lavender, those products do not do what they say. Through one of my FB groups I saw that a lot of people used Happy Camper so I decided to give it a try. This stuff works better than anything I have ever tried. It says one scoop, but I do 1 and a quarter to a half in my large black tank. I don't worry about odor unless my tank is almost 100% full. I have bought this again, and will continue using this over any other product. I am 100% satisfied with the results. Its a little pricy, but it works well enough to offset the cost. Hope this helps! ... show more

    • THIS is the tank treatment solution you want!
Amazing product! I live full time in a fifth wheel camper and was previously using Bio-Pak tabs for black tank treatment; they worked decently, but this powder? Whole other level. I dump the black tank once weekly on Sunday, prefill the freshly emptied tank with about 4 gallons of water and one Happy Campers treatment before resuming regular use, and have no odor come back up through the toilet until Friday or Saturday. The odor that does come up is still much less offensive than when I was using Bio-Pak. Even dumping the tank is less smelly and faster, as it breaks down everything very efficiently. Happy Campers may seem more expensive than brands upfront, but per treatment it's only about 10 to 15 cents more (on average) than less effective competitors - WELL worth it! If you want true odor elimination, a faster dump time, and a cleaner black tank, Happy Campers is the product you want. ... show more
