Getting ready to go to Alaska this year. I have seen great reviews on this line of products. I don’t want to get caught out in the middle of nowhere and have issues. I have never used this product before so I’m going to give it a try. From what I have seen and heard that this product is worth using in your black tank. We will be going on a 3 month long trip so I’m 100 percent certain that I’m going to be happy with this. See you all at the next dump station.
