Unique RV Digest-It Liquid RV Holding Tank Treatment, 32 oz

★★★★★ 5 out of 5 stars If you're fighting flies, drain moths, or mosquitoes that seem to be coming up through your sewer lines in an RV, mobile home, fifth wheel, or portable toilet, this product is absolutely worth trying. I bought Digest-It Ultra after it was recommended by my friend Ralph, ChatGPT AI. I had reached the point where I was completely over battling the invasion of insects. I followed the directions exactly as written and even gave my sewer system a thorough flush beforehand to give the treatment the best chance of success. The live enzymes in the Ultra formula really do the heavy lifting. It helps break down waste, reduces odors, minimizes buildup in the plumbing, and most importantly, it helped eliminate the breeding ground for the insects. I noticed a significant improvement after about 3 days, and by 7 days the flies and other unwanted visitors were completely gone. After 30 days, the plumbing line from my toilet to the sewer hookup looked noticeably cleaner than it had in a long time. My advice is simple: buy the Ultra version, not the standard Digest-It. Use it exactly as directed and stick with the monthly maintenance schedule. For me, it's money well spent, and I'll definitely continue purchasing it.

Good product. Reduced odor in tanks

Did My Research After Trying Many Others – 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 purchase—and 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 effective—no 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.

this helps with the odor. The scent is not too strong it doesn’t really digest it so to speak, (are there any that really do?) but it does the job of helping keep the odor away in your black tank. I love how you can squeeze it and it measures it by itself or in the little thing and then you just pour it over and you’re not pouring too much. I’d love that part I would buy this again and again seems super safe and easy to pour.

Worked great! Cleaned the black tank out well. All sensors were cleaned, flush ran clear and no residue in the tank. Bought more Unique RV products because of the excellent quality and results.

We’ve been using this in our RV, and it’s been working great. It helps keep the holding tank under control and does a good job with odors. Easy to use, and a little goes a long way. I’ll definitely keep buying it for our RV. Highly recommend!

Great product and the only one we use for the treatment on our 5th wheel. We've had no issues.

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. I’m 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 don’t have a lot of water to spare when flushing I do the best I can so I probably wouldn’t 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
