    • Keeps tank from clogging
To ensure the proper functioning of your RV's black water tank, it is recommended to pre-fill it with approximately five gallons of water before use. This helps to create a sufficient liquid base, which facilitates the efficient breakdown and disposal of waste. By taking this simple step, you can help maintain the cleanliness and longevity of your RV's plumbing system, making your camping experience more comfortable and hassle-free. ... show more

    • Best camper product!
This is a game changer in camper septic! We have tried several other brands and this is by far the only one that has worked at eliminating odors, breaking down partials, etc!

    • It's worth the high price you pay for this stuff.
Gets rid of the offensive odors. I want to believe this exists right in the middle my business.

    • Works - used for 5 years
This works. Used it in our TT holding tank for five years of camping. This combined with using plenty of water, we never had a problem getting the black tank empty - no pyramids. We also avoided horrible odors coming up. We also used this in the black tank with a small amount of water when we winterized. Read and follow the instructions and it will work as it should. ... show more

    • THIS is the tank treatment solution you want!
Amazing product! I live full time in a fifth wheel camper and was previously using Bio-Pak tabs for black tank treatment; they worked decently, but this powder? Whole other level. I dump the black tank once weekly on Sunday, prefill the freshly emptied tank with about 4 gallons of water and one Happy Campers treatment before resuming regular use, and have no odor come back up through the toilet until Friday or Saturday. The odor that does come up is still much less offensive than when I was using Bio-Pak. Even dumping the tank is less smelly and faster, as it breaks down everything very efficiently. Happy Campers may seem more expensive than brands upfront, but per treatment it's only about 10 to 15 cents more (on average) than less effective competitors - WELL worth it! If you want true odor elimination, a faster dump time, and a cleaner black tank, Happy Campers is the product you want. ... show more
