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.
Review: Does what it says on the label - I live in an American RV in the UK. I previously used different options for the black tank. There was always a lingering smell, especially when it got hot in the summer. I was recommended this product by another RV'r, and I must admit it is very good. There is zero smell, and being organic, I can use it in the RV park, which doesn't allow chemicals. Very happy to recommend this. Yes it is expensive but it is shipped from the USA

## 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: 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.

At last….. drain grey water in public without the nasty odours, cannot believe how this product just simply banishes grey tank stink. Even in very hot temperatures open the valve, no smell, marvellous.
