Expensive but 1 tub lasts for years of touring. - I have tried all the caravan toilet treatements over 40 years. Uk dealer shops are stuffed with competing heavy, bulky liquid products. This is #1 in the USA primarily for their large live in units. I use 1/2 teaspoon of the white powder in the touring caravan WC waste tank. One tub lasts me years. Also this treatement works much better than 'our' smelly liquids in hot weather. I suspect not on (shop) sale in the UK because this would cut profits. Review: It really works! - I had heard about 'Happy Campers' when I was visiting some friends in Florida who had their own RV (apparently this stuff is legendary round US Campsites). I myself have a boat with a black waste holding tank, which has a tendency to emit some nasty smells whenever flushing or otherwise agitating the tank. The instructions are precise and following them, you wont go wrong (only niggle is its all in US Gallons, but this is an imported thing), just put one scoop in a toilet filled with water, and flush. My tank is around 250L, so around two large scoops with two full bowls of water should be enough. After using just one treatment, I've already noticed a huge difference - so far absolutely no odours! I'm shocked!! So much better than the Blue stuff that people use. As the package says, it doesn't mask odour, it eliminates odour. We are due a pump-out of the tank in a month, so will update so far as how it dissolves toilet paper and other material. ## Features - Causes serious eye damage. - Harmful if swallowed. - Very toxic to aquatic life with long lasting effects. - Very toxic to aquatic life. - Odor free: absolutely no chemical or sewer smell - Organic: biodegradable, environmentally friendly, septic tank friendly - Effective: in extreme hot & cold temperatures ( over 100ã‚â°f ) - Extended dump interval: keeps on working ( don't have to add more before dumping ) - Liquify: waste solids & most ordinary household tissue ( no expensive special tissue needed ) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005XEFADU | | Allergen Information | Allergen-Free | | Benefits | Controls black & gray tank odors | | Best Sellers Rank | 220,305 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 978 in Camping & Hiking Hygiene & Sanitation | | Brand | HAPPY CAMPERS | | Brand Name | HAPPY CAMPERS | | Contains Liquid Contents? | No | | Customer Reviews | 4.7 out of 5 stars 13,637 Reviews | | Item Form | Bar | | Item Volume | 18 Fluid Ounces | | Item Weight | 1.13 Pounds | | Item form | Bar | | Item volume | 18 Fluid Ounces | | Manufacturer | RV Concepts | | Material Features | Biodegradable, Natural, Organic | | Material Type Free | Formaldehyde Free | | Material feature | Biodegradable, Natural, Organic | | Model Number | HC-18-oz | | Number of Items | 1 | | Part Number | HC-18 | | Scent | Unscented | | Size | 1 count (Pack of 1) | | Special Features | Biodegradable, Concentrated | | Specific Uses For Product | RV Holding Tank | | Specific uses for product | RV Holding Tank | | Surface Recommendation | Sink, Toilet | | UPC | 186045000028 | | Unit Count | 1 count | ## Product Details - **Brand:** HAPPY CAMPERS - **Item form:** Bar - **Item volume:** 18 Fluid Ounces - **Material Type Free:** Formaldehyde Free - **Material feature:** Biodegradable, Natural, Organic - **Scent:** Unscented - **Special feature:** Biodegradable, Concentrated - **Specific uses for product:** RV Holding Tank - **Surface recommendation:** Sink, Toilet - **Unit count:** 1 count ## Images ![Organic RV Holding Tank Treatment - 18 Treatments | Controls Odors, Helps Prevent Clogs, Buildup & Sensor Issues, Black & Gray Tanks, Supports Reliable Dumping - Image 1](https://m.media-amazon.com/images/I/71QLIdZE91L.jpg) ## Questions & Answers **Q: What is Happy Campers RV Holding Tank Treatment?** A: Happy Campers is a highly concentrated and proprietary blend of minerals and micronutrients. It's a water-activated powder treatment designed to eliminate odors and break down waste in RV and marine black and gray holding tanks. **Q: How do you use Happy Campers Tank Treatment?** A: Just add One scoop (or one treatment) equals 2 tablespoons after every tank dump. 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: What if Happy Campers Doesn't Work?** A: We stand by our product and customers. However, if you try the treatment and still have odor problems, this is most commonly solved by adding more water or making sure to deep clean your tank prior to using the regular treatment. **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 ### ⭐⭐⭐⭐⭐ Best touring toilet holding tank treatement by far.
