I rent out my rv and a client was dry camping and clogged the toilet and tank. I dumped 1/2 of this down the toilet where I could see solid waste. 10 minutes later when I was going to add water I could already see that it was liquifying the waste. Saved the day removed all smells and I was able to deliver to my next client.

Haven't been out in the trailer since I got this but reviews are good. So hopefully it works better than what I was using.

To all the thousand +++ RV Folks out there; look no further for your Black/Gray system tank treatment products. This additive to your tanks REALLY DOES WORK, I mean Seriously the biodegradable contents eats away at all this nasty stuff, cleaning your tanks, positively REMOVES ALL THE ODOR COMING FROM THE SEPTIC TANK! The product comes in different scents (Citious my favorite). I’ve tried them all, nothing compares to this product. Try it, you will not be disappointed, Trust me, I wouldn’t say it, if I didn’t mean it. 6 Stars in my book

Have tried numerous other black water tank additives and this one has worked the best!! It turns the entire solution into a uniform light brown & seems to breakdown all the toilet paper as no pieces are seen when draining tank. No issues with smells coming up out of black water tank when flushing.
