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

This one works the best of many we have tried.
