When spending your days in an RV with black and gray tanks, Unique products are a must. The Unique RV Digest-It Ultra RV Toilet Treatment works well, is effective at dealing with tank smells and breaking down waste. It is extra easy to use with the new measuring section of the bottle. A great value and works better than most products.

The media could not be loaded. I believe this stuff works great. Since using it, I’ve had no issues with clogs, dumping has been easier, and the tank sensors seem to be reading correctly so far. It definitely does what it claims in terms of breaking everything down, and I like that it works in different camping conditions. That said, the smell is pretty strong and honestly reminds me of straight urine when you pour it in. It doesn’t linger forever, but it’s noticeable at first. The odor of the product does make me feel iffy on using it but it does its job.

Have owned campers/RV for decades. I have used many different black tank chemicals. Some worked a little, some didn't work at all, this is the best treatment that I have ever used. I am done trying other products, this is the only one that I will be using. One oz per 40 gallons and when I dump black tank I have Never seen any solids or toilet paper going out. I have a clear straight pipe and a clear elbow to monitor the discharge. I back flush using tank clean out every time and still nothing but water leaving. Every so often I will use a flash light and look down into the toilet with the water turned off so I get a good view. Have seen Nothing but the clean tank bottom. Works Great.

If you’re irritated by our “do gooder” government doing away with formaldehyde in rv tank treatment as I was, then this is the new and improved “blue stuff” we use this in a porta potty at deer camp, the toilet gets emptied every 2 days and with this stuff there is zero sewage smell and when it comes out it’s just toilet paper and brown water, it literally turns the waste into liquid, it’s great! I can only image if you don’t empty an rv tank but once a week it may eat up the toilet paper also. Really good stuff.

Doesn’t contain odor as claimed, but does liquify waste effectively
