## 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 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.
