Review on 🚽 Camp Champ RV Super Digest (16oz) - Powerful Enzyme Blend for Complete Liquefaction of Organic Waste in Holding Tanks! by Mark Tarnowski

For reviewers complaining about bad smell, that's fine. This is not some kind of fruity scented black tank odor masking liquid. This product is a concentrated form of several bacteria that will safely clean your aquariums. If you know any science, you know that bacteria (especially the bacteria that break down black garbage) smell bad. Honestly the smell is so bad which is the only reason for the 3 star rating. I ended up using that with Camco Lemon Gray Water scent to even out the smell, it probably counteracts bacteria a bit with its detergents but it's better than smelling that stuff out of my tanks when I'm driving down the road. So TLDR: cleaning tanks is great, but bacteria smell like raw sewage. If you need something for general use this isn't it, but it's great for the occasional cleaning or breaking through any blockages or clogged sensors.
