Been using a liquid no formaldehyde black tank digester and thought it was working fine until a friend bought Happy Camper and said that the black tank smell he was having now disappeared. So when my current treatment was used up, I order this and am pleasantly surprised that I also have no stray black tank odor at my toilet. It is easy to measure and I have mixed it in a plastic gallon jug to make it easy to just pour in my tank. It seems a bit pricey but I will get plenty of scoops out of the size I purchased. For me just one scoop per tank size is all I need. Cheaper per unit measure than the liquid in pour size bottles that “Happy Camper”. 😆🚽

I've been using a different RV tank treatment since we bought our travel trailer 11 years ago, but there was often a very unpleasant odor from the black water tank that wafted through the trailer when the valve on the toilet was cycled. This Happy Camper treatment was highly regarded by other RVers based on other reviews I read from various sources, so I gave it a try. We've been using it for our last few trips, and I couldn't be more pleased. It's really easy to store and dispense, and eliminates almost all of the odor emanating from the black water tank even when it's moderately full.

Wow this stuff is amazing. We live in a camper our black tank was starting to smell every couple of days and we tried everything and nothing worked until we bought Happy Camper, it lasts is easy to use and is very effective at getting rid of odors. Use it by the directions on the label.
