Gets rid of bad smells .
Our waist had to wait to be drained for 2 months. I continued to use it through those months and we were able to drain the tank after the two mo the and the waist ran clear. Amazing product. Really works well

Did My Research After Trying Many Others โ This Is the One!
Did My Research After Trying Many Others โ This Is the One! After trying several RV toilet treatments over the years with mixed results, I finally did some serious research before my next purchaseโand Unique RV Digest-It+ is the one I landed on, and so far I'm convinced it's the best I've used. The extra-strength formula does an impressive job of liquifying waste and breaking down all brands of toilet paper without leaving anything behind in the tank, which is exactly what you need for a clean, problem-free black tank. The odor elimination is noticeably effectiveโno chemical smell, no unpleasant odors coming back up through the toilet, just genuinely fresh results. For RV use where black tank maintenance is a critical part of every trip, having a treatment you can actually trust makes a real difference in the overall experience. It's also reassuring that it's safe for all RV and marine holding tanks and septic systems, so there's no concern about damaging seals or sensors. After testing many products, this one stands out for its effectiveness, reliability, and clean results. If you've been bouncing between RV toilet treatments looking for the right one, do yourself a favor and make this your last stop.

Great Black Tank Cleanerโฆ
If youโre looking for a chemical that does a really good job then look no further than. I noticed since I started using this companies chemical my black tank No Longer smells! It really does a good job on getting my Black tank cleaner. Instead of cleaning my black tank 3 to 4 timesโฆ. Iโm now doing it just Twice. Thumbs up for this product!

Amazing Tank Treatment โ Works Exactly as Promised
This stuff is amazing. Iโve been using it for about a year now, and it truly breaks down all the solids in the holding tank into a liquid or sludge, which makes dumping so much easier. It does exactly what you want a tank treatment to do โ everything dissolves properly, and thereโs no buildup left behind. One of the biggest benefits Iโve noticed is that my tank sensors have become much more accurate since using it. Anyone who owns an RV knows how frustrating those sensors can be, so that improvement alone makes this product worth it. Overall, itโs effective, reliable, and makes tank maintenance far less of a headache. Highly recommended for any RV owner.

It worked, but I had to use the whole bottle and it was a little pricey
I like it I would buy it again. I do say it was the best toilet treatment that I ever used for my RVs. I did have a pyramid plug, but I did have to use the whole bottle. It worked with breaking up tissue and breaking up the pyramid Plug, but I still had some lingering smells. Iโm going to at least keep it in my toilet for 3+ weeks because my septic system is not full yet and I only get it dumped out about twice a year because I have a large septic system so it will have a lot of time in my system to work but at the same time it took the whole bottle to be able to get rid of the smell and actually work I know it stated that it was 32 treatments. It was a little less than $30 and it was only one treatment for me. I did use about 20 gallons of water after just to push everything through the system. I live off grid where I donโt have a lot of water to spare when flushing I do the best I can so I probably wouldnโt have this problem if I had endless water to where I can use as much as I needed it to flush and also keep some water in my toilet bowl afterwards, but it did help me with my problem, but I did have to use the whole bottle so it was worth the $30 to help me with my problem, but most definitelyexpect to use the whole bottle at least half of the bottle when purchasing

Does the trick and has lasted the full camping season.
When the black tank is drained, waste flows easily because it is broken down ... no more clogs and no more stinkies.
