Happy CampersHappy Campers RV Toilet Treatment 18 - Extra Strength Odor Eliminator for Black and Gray Holding Tanks

This is a 5 star product. Just add each time you drain the black water tank and no problems. No funky smells ever. No perfume or chemical smell.Just ALWAYS cover your toilet donut with approximately 2 inches of water.

We have tried several different products and like the Happy Camper the best. We no longer have black tank odors like we have had with so many other products when staying at one place for several weeks. The only thing is that when driving, there is a smell due to sloshing of the "stuff" in the tank, but the odor id gone an hour or so after we stop. Even with that, this is the best we have found for when we are parked! Just ordered a second jar and will continue to use this as our primary black tank treatment.

This works so well! It is a must-have! The smell from our black tank went away and it completely liquifies everything. It's so perfect. We use Angel Soft TP. Works great.

This works better on odors than anything we have used. I put in one scoop each week (and then dumped at the end of the weekend) and it worked great.

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.

Good stuff for the camper. Keeps the stink to a minimum.

As an avid RV enthusiast, I recently tried the Happy Campers RV Toilet Treatment and I am very impressed with its performance.The treatment is very easy to use and quickly breaks down waste and toilet paper, leaving my RV's holding tank clean and odor-free. I appreciate that it is made with natural and biodegradable ingredients, making it safe for the environment and my RV's plumbing system.One of the things I like about this product is that it is very effective at controlling odors. Even after several days of use, my RV's bathroom still smelled fresh and clean. The treatment also helps to extend the time between pump-outs, which is convenient when I am on longer trips.The treatment is also very affordable and provides good value for the cost. A little bit goes a long way, so a single container lasts for several uses.Overall, I am very satisfied with the Happy Campers RV Toilet Treatment. It is a reliable and effective way to keep my RV's holding tank clean and odor-free. If you are in need of a quality RV toilet treatment, I would highly recommend giving this product a try.

I don’t know what they put in this stuff, but it is the best toilet chemical deodorizer I have ever used. We have had an RV for over 20 years now, and have tried everything. I kept hearing about this, but held off because of the cost. We had a situation come up where we couldn’t dump our black tank for 2 weeks. This happened a year ago as well, and we used the chemicals from the big box store back then. We added twice the amount called for to keep odors down, and the odors were soooooo bad after two weeks! It took us at least a month to finally get the odors out. So, when this same situation came up, we were desperate, and decided to buy this. We used overnight shipping so we could get the chemicals in there fast. After two weeks, I entered my camper’s bathroom, expecting to smell at least a little odor. Nope! I shook my head in disbelief as I opened the toilet seat, expecting to faint because of the odor. Not one odor vapor was to be found! Zero stench! Zero!In conclusion, this stuff is pricey, but ohhhhhh so worth it if you find you can’t dump your tank for a few weeks. I am totally sold!
