  • Use the best, forget the rest
Style: Extra-Strength Size: 32 Fl Oz (Pack of 1)
Use this. Follow the directions. Don't worry about your RV's black tank ever again. I started with the Camco stuff, and after reading about Unique, I would never use anything else. It's pricier, but it dissolves waste and keeps your black tank functioning exactly as you need. No unpleasant odors, even after months of the RV being parked. ... show more

  • PROOF IS IN THE PUDDING-LIKE DIGESTED DOG KIBBLE
Style: Classic Size: 32 Fl Oz (Pack of 1)
A few years ago, I conducted a similar experiment, comparing black and gray water tank treatments using dog poop. In that experiment, TankTechsRx came out the winner over the other product (I’m sorry, I no longer remember that product’s name), as it did a much better job of reducing the odor. I recently encountered this product, which had good reviews, so I bought a bottle of it—Unique RV Digest-It—to compare with my TankTechsRx. Unique showed how their product would digest dog kibble, and that it has a similar composition to human waste: protein, fat, carbohydrate. So I tried it myself. The experiment was this: I mixed a capful of each product with water to nearly fill a small glass, and then I placed five pieces of small dog food kibble in each glass and let them sit. The photo showing the glass with the brown colored liquid is the one with TankTechsRx product, which is naturally brown. Result: Within 12 hours or so, the Unique RV Digest-It had reduced the kibble to a sludge at the bottom of the glass, whereas the glass with the TankTechsRx still held solid chunks of kibble. The odor was also different, with the TankTechsRx glass smelling a bit funky, while the Unique RV Digest-It glass had a faint, but rather pleasant, almost floral, smell to it. I will be using Unique RV Digest-It from now on in my gray water tank. We have a composting toilet, so we don’t use a black water tank. However, we have been spraying a mixture of water and TankTechsRx in our composting toilet, which has seemed to help with the composting process and odor control. I will now be trying the Unique RV Digest-It in the same way, expecting good results. I would surmise from my experiment that Unique RV Digest-It would work well in a black water tank and accomplishing what it advertises: 1. BREAKS DOWN SOLID WASTE INSIDE TANKS. Liquifies human waste and all brands of toilet paper. Digests residual sludge from years of build-up. Works in black and gray tanks. 2. ELIMINATES TOILET & TANK ODORS without masking. Extra strength activated cleaners eliminate odors at their source without covering them with overpowering perfumes. 3. HELPS PREVENT SENSOR MALFUNCTION. Cleans and removes solid waste and paper before it can cling to sensor probes, preventing misreads. Yes, I have no association with either company. Yes, I suggest others give Digest-It a try. ... show more

  • One of the better RV tank deodorants
Style: Classic Size: 32 Fl Oz (Pack of 3)
This is one of the better RV tank additives. It was recommended by our RV tech who had to clean a "poopcicle" from our tank. This keeps things liquid and no clogs in over 2 years. We live in our RV, so a good tank chemical is paramount to keeping things fresh and flowing. Cost wise, it is comparable with TSS and much better than the Thetford we were using. Admittedly, since we live in TX, in the summer we have to add a bit more to the tank to keep summer septic odors from leaking back into the living area. We empty into our son's septic system once weekly and use a macerator. The blades don't struggly with the processing of the tank contents like they did with the Thetford. Solid waste and toilet paper (quick dissolve) isquickly ground and disposed of. No clogs, which makes my son happy. ... show more

  • The stuff works
Style: Extra-Strength Size: 32 Fl Oz (Pack of 1)
I’ve used this about four times. Three times as my traveling treatment and another as a clean out. It works as advertised. No funny odors just clean poop. That’s why I bought it again.

  • Not as unscented as it claims
Style: Extra-Strength Size: 32 Fl Oz (Pack of 1)
It works okay. I chose this product over the others, because it said it had no scent. I have MCS, MCAS, and allergies to ingredients in fragrances, so it is important that no fragrance be in products that I use. The Unique RV Digest-It+ definitely has a slight floral scent. It was very mild and might not have been noticed by most people, but it did cause me reactions. ... show more

  • Such a relief
Style: Classic Size: 32 Fl Oz (Pack of 3)
Unique RV Digest-It works better than described and better than other products that we've tried. We've also used other products that Unique offers and have never been disappointed.
