Four years full time boondocking on the move, Unique has been an incredible product but always open to trying new stuff that is not a chemical scent bomb.

[@jameshodgins1937]

First test and second test same results. I would suggest to all the people that want better or different, please feel free to run your own tests and share your results with us. Todd, you guys do a great job.

Thank you for the support!

[@kevinclark1348]

I use Unique, have done so the last year and have zero issues. Breaks down great, flows out just fine when dumping. The clear elbow on the end of my sewer hose helps see how great this product is. Safe travels!!

I have been full-timing for 14+ years and Liquified was the clear winner. I was stubbornly holding on to my belief that Happy Camper was going to be the clear winner, but noticed that Happy Camper was taking 4 scoops in order to even come close to the same performance ... I digress! Liquified dissolved into tiny pieces all of the less-than-perfect brands of TP so that we had no more build-up in our tank. It DID NOT do anything for our gray tank which was experiencing a buildup of grease on our sensors. Liquified needs to come up with a gray tank cleaner as well. -Davey

[@dwaineesch1344]

why couldn't you just add Liquified to the grey tank?

[@KU9L]

@@dwaineesch1344 I did double the dose in the gray tank twice over a couple of weeks, but it did nothing for the sensors in the gray tank, grease takes different chemicals to remove it.

[@josephharrell5724]

To be completely scientific there should have been a third sample with just water to see how much it dissolves with no product at all. This would be the control group.

Thank you for the comment. Did you see our previous video where e did just that? Here's the link! kzbin.info/www/bejne/gZeQip1_mZKpY8U

[@randygonzalez6250]

Actually to be completely scientific he would've used two separate teaspoons thereby not contaminating the "Liquified" sample with the "Digest-It", but why not have a deliberate test of both products combined to begin with, in addition to your precious control group? Enzymes are critical for digestion but so are probiotics, so I don't understand the purpose of restricting this experiment to an "either or" scenario. Not that I care, I just teleport my black tank contents into a black hole via interdimensional portal technology.

I used Unique this last summer. It did very well at breaking down the waste, but I was not impressed with the Oder elimination(or lack of)! I am definitely going to try Liquified this summer.

[@severecracker3640]

Been using Liquified, It works well. I’ll stick with it.

[@tywebb9879]

Great video Todd, and agree with your analysis but water is your friend. Good (tested) chemicals, good level of fluids, good rinse is your friend.

[@mikewatkins978]

Hi Todd, 5 months later, I purchased the Unique before watching this vid and decided to go ahead and use it this year, Each time I dumped the tank it only took one maybe two complete fill & drains of the tank for the clear elbow to be clean running tank water. After two complete fill & drains of the tank with clean water so to test the difference best I could, half way into the trip I switched over to a drop in packet style of tank treatment, Not pleased, not near the break down of solids or paper in the same time period between dumps,,, and within two days my sensors started to misread leading to several stops only to end up draining a 1/4 full tank. To use Unique you have to pre treat the tank to remove the enzyme based treatments before using a bacteria based treatment I was stuck finishing the trip out using the packet treatments. At one stop, I flushed the tank several times and solids were still present, where as with the Unique when finishing the second flush there were none seen in the clear dump elbow section of my dump hose. Home now and using the Unique pretreatment, that I had also already purchased, to clean the tank of the packet formula Due to the expense of the products I will wait until the Unique is used up before trying the Liquified. As far as odor is concerned, if you have the air conditioning on or a roof vent fan it's going to draw the odor up out of the tank when flushing, I suggest that you shut off the fans & AC during the use of the toilet so it's not near as bad.

[@TheBirdandEagle]

Its no real poop, but close. Great video. Thank you.

[@riseup3117]

Great analysis Todd. The problem addressed by a Guy who does tank cleaning for a business with many years of experience claims this slurry created by both products coats the walls of tank creating overtime a large layer which will shut off the tank sensors.

[@EarlBalentine]

Great video.

[@NationalRVTrainingAcademy]

Glad you enjoyed it!

[@uberpain1]

User Unique last year and worked well but still had occasional odors while traveling. Going to try liquify now after your testing. Thank you so much for the great content and straightforward presentation. Have 3 ladies, DW and 2 daughters so the toilet paper is key for me!

[@NationalRVTrainingAcademy]

Thanks for sharing!

[@mikewatkins978]

Good morning Todd, it was interesting to hear that Unique needs a deodorizer additive, must have something to do with them residing together before use, I will have to get some for my testing this year. The "comment" section testimonials are also very helpful and I think that's where we're going to find our "Real World" results. Not until you do a video on this topic do you get that feedback so thanks for taking the time to put together this video. Maybe compile a file of those to refer to, Also maybe a co-operational/interview video with real world tank cleaning companies and independent tank service people to get their "Very Real World" feedback. Some comments have stated that you didn't agitate the test tanks and that would change the results, well for those people, you would have to drive like a nut case to get much agitation in the tanks, I've seen a test done that way too and it made no difference so when you tell your story to the state cop be sure to tell them that you're testing your holding tank treatment. For those wondering about the treatments helping clean sensors, maybe in the gray tank if you rinse a LOT of grease off your cookware, but if your sensors are not working then 99% of the time it's an electrical issue, the ones I've fixed just needed the wire connections cleaned & secured. they're exposed to a lot of road dirt & salt Again, thank you Todd & company for your efforts.

[@JandAReview1]

We use aqua max not only in the black tank, we put it in the gray tanks. We have noticed it help with the sensors too have it in the tanks as we travel. Definitely helps with kitchen gray tank from not smelling so bad.

[@NationalRVTrainingAcademy]

Thanks for the comment!

We use RV Digest It and it works well for us. We don't have odor problems at all using it. I'm sure others will like something else so just use what works for you.

[@mondavou9408]

I have used Digest for years (weekly dump schedule) and have found it to work well. I'm looking forward to trying Liquified. I appreciate the exposure to a new product, that has been tested rather than just shamefully promoted.

[@mikep8085]

when dumping black tanks, does sludge exit the tank like solid would? To me, it seems like the sludge would just settle at the bottom of the tank.

[@scottd143]

Great test, it is amazing how many people want to critique and complain about your process. Funny thing, there were two commercials during the video, one was for champagne and had a girl singing "go, go. go," and the second, Taco Bell.

[@GaryNichols50]

GO LIQUIFIED!!!!!

[@BassFever4Ever]

I tried Unique last year after I got my rv back home from a weekend trip. I filled up my black tank about a third and put the treatment in and let it set overnight. There was quite a bit of matter that came out. The next handful of times we went out, we used the Unique product. After getting home each time, I would repeat what I did above, and the liquid was pretty much clear. The only issue was black tank odor. I will give Liquified a try. Thanks for the video! BTW, I have a dump connection to my septic system just in case some might think I'm dumping on the ground lol

[@chip812]

Looks like Liquified works slightly better, but it looks like either one will work just fine.

[@rickpaul4627]

Todd, we have a newer RV with macerating toilets so TP and "solids" are not an issue. Also the tank sensors are external so buildup has not been an issue. We typically dump every 5 days but only add a product about once a month with water while driving. Just wondering if any of your recommendations or testing would be different in this situation. Thanks!

[@ketorising81]

Still having some odor issues here. Is it safe to add some detergent or dish soap to a black tank treated with Liquified?

[@sopascat7]

… I use Liquified a few times for my grey & gallery tanks. I use Green Gobbler (for RVs) in my black tank. Still had a bit of oder…Kleen Tank RV company said use a good amount of water when flushing. The smell reduced since flushing w/more water.

[@vincentgonzales8917]

I have a 38ft 5th with 6 point LCI landing gear and between wheel stabilizers. I also use strong arm bars. When my grandkids are playing around in side you still get some motion, which may not be much but is still going to swish the liquid in the tanks some. So maybe a gentle swish mimicking that motion would have been a real life senerio. Both products would've done a bit better.

Just remember, a black tank is a HOLDING TANK, not a septic system. Use the RV toilet paper and plenty of water.

[@timothyordway6460]

When you add water to your black holding tank how much water is in the tank? Some say 3 gallons is about average. But how much of that water goes down the pipe to the shut off? A 3" pipe holds 0.4 gallons of water per foot. So on my RV the pipe is 6 feet long from tank to valve, which is 2.4 gallons. I put 5 gallons of water in my tank which leaves about 2.6 gallons in my tank. Now I know there is water in my tank Thank you for all you do Todd

[@NationalRVTrainingAcademy]

I agree 5 gal minimum. You would be surprised of how little water is added each time you go. So starting off with SUFFICIENT water covering the entire bottom of the tank.

When they say ad water - common sense tells me that water covering odor on the sides of the tank that doesn’t mean that it’s any better than any other product. You can fill it up to the top and cover poo walls with any product It’s when it’s empty and then rinsed out. Does the smell still stay? That’s my question so I am using Unique now and still smell odor so we will see and we use lots and lots of water.

With all these videos comparing the different brands... the only thing that isn't being replicated is that our RV black/grey tanks are not air tight, they have roof vents.
