    • It's real, it works
We have been using this since we bought our motorhome 2 years ago. We have no odor problems, we have had no clogs. This stuff does what it says it will do. When dumping the black tank everything is liquid as it should be to keep everything flowing smoothly. But, when you clean your toilet do NOT use products that will kill the good bacteria In Unique. They have a cleaner for your toilet that also contains the bacteria that keeps your tank working properly. Try this, if used properly you will not regret it! ... show more

    • Better than the pods.
So thought I would try this product out. I was always using the TST pods. I bought a small bottle to give it a try. Well worked great. I then bought the big one. You can also use this in your gray tank. Which the TST pods are only good for blk tank. Smell. Nope. Only use 1/2 cup. It's a must have for me now. Versatile ... show more

    • So far the best RV holding tank stuff I've tried.
I've used 5 other types/ brands but I've had best results from this. I've been a full-time RV life for around 12 years. I recommended it to quite a few others, in fact I gave a bottle of the accompanied toilet bowl cleaner to a friend who had just bought a new 5th wheel RV.

    • It WORKS!
We camp a lot and I've tried various ways to keep our black tank operating smoothly. I can safely say that Unique RV Digest-It Holding Tank Treatment is the best I've found. It just simply works as advertised. Use it as directed and you should get a black tank that works like its suppose to. I use it on the grey tanks as well to remove grease and oils. Keeps everything smelling better too. ... show more

    • Best product we found
This one has been the only product that solved the odor issue in bathroom RV. It got it under control. We buy it by the gallon which lasts us some time. Easy to use & order.

    • Excellent Product
There are lots of products out there that claim to be the best for cleaning the black tank in an RV. There are many that I have purchased in the big box stores that leave a great scent but do a lousy job at preventing "poop pyramids". This product, which contains microbes that naturally dissolve the paper and solids in the tank. It is the best product I have used in the the 35+ years in RV'ing. ... show more
