    So far this is the best black water tank treatment I've found. Will echo it eliminates the holding tank odors but am also impressed that I have had my 2011 camper for a couple years and have been trying several products and ways to clean out as the sensors do not operate correctly. After a couple treatments of Happy Camper I'm getting better accuracy on the sensors. I've also added to the gray water tank following instructions on package and can say that's also improved and a cleaner tank. I bought the one time use holding tank cleaner too, but haven't had the chance to use. I'll probably use just before when winterizing the camper. Great product. Wish it came in convenient packs but understand a scoop of this needs to be dissolved in a gallon of water first otherwise the product will get hard as cement and be like chunks of gravel.

    We are COMPLETELY in love with Happy Campers holding tank treatment. I discovered it on line several years ago, and after years of camping FINALLY found a product that really keeps the black tank odors away. We are seasonal campers and use it 6 months of the year. As long as you follow the instructions and remember that water is your best friend, it works like a charm. We have recommended this to at least 6 other camping friends who also use it as their only method to keep their tanks clean. I recently could not get a supply on line at Amazon and literally went into a frenzy thinking the product was not being made!! Thankfully, I went directly to your website and was able to restock. It's one of those products that if it wasn't made any longer, I'd be beside myself if we had to replace it for something else!!!!!!!

    Received the tub in a timely manner. Set 1 scoop in both the gray and black tanks. Waited 24 hours and we now have no odor when the tank is opened. It really works! and works well.

    We have used Happy Camper holding tank treatment since about 2005 and we think it is the best. It works great in grey tank, also, so that it doesn't have any odor when the tank is dumped, or, worse yet, leaks. Use Happy Camper with lots of water in the black thank and you should never have a problem.
