What is Happy Campers RV Holding Tank Treatment?

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.

How do you use Happy Campers Tank Treatment?

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.

Is Happy Campers safe for RV plumbing and septic systems?

Absolutely. Happy Campers is safe for RV plumbing and home septic systems. It contains no formaldehyde or harsh chemicals that would damage seals.

What if Happy Campers Doesn't Work?

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.

Does Happy Campers work in all types of campers, holding tanks, and cassette toilets?

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.
