It's a water-activated powder treatment designed to neutralize odors and break down waste in RV and marine black and gray holding tanks. **Q: I lost my scoop, how much is in one scoop?** A: One scoop (or one treatment) equals 2 tablespoons. Use one treatment per 40 gallons of holding tank capacity. For example; if you have an 80 gallon tank, you would use 2 scoops with 5-6 gallons of water to prime tank. **Q: Is Happy Campers safe for RV plumbing and septic systems?** A: Absolutely. Happy Campers is safe for RV plumbing and home septic systems. It contains no formaldehyde or harsh chemicals that would damage seals. **Q: Why can’t Happy Campers be shipped to California?** A: California SB 317, pertaining to chemical RV tank treatments, contains language broad enough that Happy Campers decided not to sell into California for compliance concerns, though the product does not contain any of the listed banned ingredients. **Q: Does Happy Campers work in all types of campers, holding tanks, and cassette toilets?** A: Yes. It works for all marine, RV, camper and portable tanks and toilets. For smaller tanks (e.g., a 6-gallon cassette toilet), use a reduced amount, such as 1/4 to 1/2 scoop, mixed with 1-2 gallons of water. Adjust as necessary. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by C***R on April 29, 2026* So far so good, our tank was a little smelly for the first time.

Perfect item. ### ⭐⭐⭐⭐⭐ Work greatbto eliminate odor *by P***K on May 24, 2026* It works really great! We have a sailboat and put it in our holding tank and the odor disappeared. Really good product!! ### ⭐⭐⭐⭐⭐ The Failproof Recipe *by T***H on March 15, 2015* I've had to travel for decades for my type of work (energy industry) never had any problems until my recent purchase of a 1 yr old 5th wheel. Unit is like brand new. Obviously the previous owner failed to dump properly and had some build up. So I thought I'd share what worked for me in this situation and try to help others. From the MSDS (material safety data sheet) Happy Campers consists of Zinc salts and unnamed minerals. Worked extremely well for me in regards to cleaning up the black tank. Using product as specified. They also make an extreme cleaner for really serious problems. To keep your black tank and sensors working perfectly.... Here is what works like a champ for me, and maybe it will help you. Understand that water is your best friend for holding tanks. Just common sense follows. Each time after I dump my tanks, I take a common 5 gallon bucket and fill almost full with water. Then take 5-6 ounces of Dawn dishwashing liquid mix into. If Hard water is a problem in the area that you are at.. Add A cup of Calgon water softener. If unavailable use old fashion Borax. Pour straight into the toilet. To start your "new" tank. This only takes a few minutes and you are giving your tank a head start. The dishwashing liquid and Calgon keeps the tank walls slick and sensors clean and reading properly. Mix the Happy Camper in the bowl with water and flush and your ready to go! For a heavily sedimented tank this may take 2-3 regular cycles of dumping to clean your sensors and clean your tanks. Happy Campers product truly does virtually liquefy all solid waste and toilet tissue. I personally have never used a holding tank product that works so well. This simple method that I'm writing has worked perfectly for myself and many many others that I known and is not just a wishful thinking type deal... I promise you. It only takes 1 time of black tank problems for folks to get real interested in holding tank maintenance! Lol 1. Dump only when tanks are 2/3 or more full. I try to get mine s full as possible by adding pure old tap water if necessary before dumping. The more water will certainly always help move any sediments. 2. There has been zero odors of any kind using this method. 3. You can use any brand of toilet tissue you like using these instructions. It truly liquefys everything! 4. Has worked for myself and friends in all temperatures below zero and 110+ climates. 5. I think you'll be quite happy with the results and please pass it on to other RVers if you get the chance. 6. Sensors make take few cycles to begin reading properly and to be clean enough to read properly, but it will happen. I hope my experiences help a few folks out there. Have a good day. ## Frequently Bought Together - Happy Campers 64 Powerful RV Holding Tank Treatments for Total Odor Control of Holding Tanks - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Water Filter - Made in USA - Camping Essentials for Fresh Drinking Water (40043) - Scott Rapid-Dissolving Toilet Paper, 12 Double Rolls, Sustainable, Septic-Safe, Toilet Paper --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/704171900-happy-campers-rv-toilet-treatment-and-holding-tank-treatment-controls](https://www.desertcart.us/products/704171900-happy-campers-rv-toilet-treatment-and-holding-tank-treatment-controls) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-12*
