Welcome to the HAPPY CAMPERS STORE . . . #1 Selling Organic, Eco-friendly RV Tank Treatment and Cleaner on the market!


How Much Should I use per dosage?

Black Tank:

Fill your toilet with approximately 1 gallon (full bowl) of water, then sprinkle and stir one scoop of Happy Campers and IMMEDIATELY flush. For hot climates and tanks over 40 gallons, repeat the above and then add two more gallons of water. IMPORTANT: Never add more than one scoop to approximately 1 gallon of water. Simply adding more water will improve your tank functions. Note: if you stir in with your toilet brush, it will stay nice and clean too!

Gray Tank:

You do not need to treat this tank every time you dump, but if your gray tank gets an odor the bad stuff usually grows from the top of the tank down. If this happens, you need to treat it with happy Campers (two or three scoops should do it) . Easiest way to treat the odor is to sprinkle and stir 2 or 3 scoops into a large bucket until well dissolved and pour down kitchen sink. Then finish filling tank and let sit over night. If you are moving right away you can do the same, even better by filling the tank to approximately 2/3 full for agitation while traveling and rinsing it when arriving at your next destination.

Will this work on old solids that have been in the tank for a while? Our sensors are dirty and have not been working for a long time.

Happy Campers Holding Tank Treatments is used to eliminate odors. If your tanks need a good cleaning, try our Extreme Cleaner to remove solids in your tanks. Click on the words in the tab above "Tips For Tanks" and go to section titled EXTREME CLEANER for more information.

Does this product take the place of the orange, blue or green pucks you add after each dump and before using the toilet again or does it serve a different purpose?

Happy Campers Holding Tank Treatments replaces your existing chemical treatments.

Will this product work in a tank that has previously been treated with a formaldehyde product?

Happy Campers Holding Tank Treatments can definitely be used if you have previously used a formaldehyde product. We recommend flushing out the tanks before beginning the use of Happy Campers, but our product is designed to break down solids and eliminate odor effectively.

Can you use Happy Campers for grey water too?

Absolutely! You can use Happy Campers products for both black and grey water tanks. It is much more convenient than liquids and has a proven track record for completely eliminating odor, not simply masking it.

Does Happy Campers treatment work in a boat tank?

Yes. An RV holding tank is typically just a larger version of a boat holding tank. The Plumbing is all the same material for the most part, and waste is… well… waste!
