Review on Treatzall - Optimal Holding Tank Treatment for Exceptional Results by Charles Davis

This holding tank treatment did not have a noticeable effect on my RV plumbing. As my tests showed, it actually contributed to clogging up the tank rather than maintaining it. While it is affordable and easy to use, the negative effects outweigh any potential benefits. Additionally, the packaging could use some improvement as it was difficult to pour out without making a mess. Overall, I would not recommend this product for automotive and RV plumbing use.
