TankTechsRx - RV Holding Tank Treatment & Cleaner - 33.8 ounce = 68 treatments - All Natural Probiotics for RV, marine, camping, portable toilets

You will never know just how good this product is and how well it will eliminate any odor problems that you might have in both your black water and in your grey water holding tanks unless you order a bottle and try it out yourself. For the past year or so my wife, who has a sense of smell that would rival a bloodhound, has been complaining of a terrible odor each and every time the toilet was flushed. Since I can't smell at all I never noticed it. I tried everything in the book to try and eliminate that problem. I flushed the tank good, bought and used a tank wand, used different chemicals both specialized products for RV's as well as a few home remedies from YouTube. Alas nothing I did made one bit of difference. Still had that odor. One night I was surfing through YouTube trying to latch on to some new ideas when I happened to run across a video advertising TankTechsRx. Needless to say I was a bit skeptical. I'm wondering why if this is such a great product for an RV holding tank then why does Camping World not stock it and sell it? I decided to research a little further and ended up watching a lot of YouTube videos of people who had used this product and reading every review I could find. In all the watching and reading I didn't see a single negative comment so I decided that I would order a bottle and try it myself. Well let me tell you friends, this had to be the best thirty something dollars I have ever spent. I flushed out the black water tank as per the instructions on the bottle, put about 5 gallons of water in and added about 2 ozs, yes you heard right 2 ozs and let it perform it's magic for about a week. My wife and I spent the past weekend in the RV and not one single complaint from her. THIS STUFF WORKS!!!!!!! Do yourself a favor and order a bottle. I don't believe you will ever regret it. I can't speak to the claim that it will clean and restore the level sensors in your tank because my RV is only a couple of years old and I am not having sensor problems as of yet. I have absolutely no doubt that it will do everything it is advertised to do. Bless the man who invented this product. All smiles here.

I have been an RVer all of my adult life. I bought my first travel trailer in 1973. I'm in my third motor home. Had a two head Bayliner for seven years. I always (years and years) used formaldehyde (six bottles in a box from Walmart) I learned about this (TT) product on YouTube. This product does the job all others claim. They don't, Tank Tech does ! I have no regrets for my past....... well there was that one time in Vegas, but in my future I will ONLY use Tank Tech in my Country Coach tanks (B & G) I go two+ weeks between dumping (black). Don't flush more than once...only when necessary 😉😉. This product obviates all others. FOLLOW DIRECTIONS TO THE LETTER ! Don't waste good product. Used properly the is the most economical tank treatment in existence. You'll see !

This stuff drastically reduces the odor in our black tank. I forgot to add some tank techs rx after draining & rinsing the black tank recently. Within less than a week the odor was terrible every time we flushed the toilet. I added some tank techs rx and the odor was gone within a few hours. Also, we have been living in our rv full time for the past 8 months & the tank sensors are still working properly. Update; We have been living in our 5th wheel rv for over a year and our sensors are still working properly. No issue with black tank clogs or odors. I drain & thoroughly flush the black tank when it gets full (about every 2 or 3 weeks). I do disagree with the instructions to leave some waste in the tank. It seems like asking for trouble with the possibility of a bit of solids getting stuck in the drain valve & causing it to leak. I put around 3 or 4 ounces of tank techs rx in the toilet after rinsing the black tank and then run a couple of gallons of water down the toilet. Works great for us.

Bought a used 5th wheel in 11/18 which had been treated with tank tech. After reviewing their web page and videos I decided that it looked like a plausible solution to the various problems of sewage treatment in an RV (odor, mis reading stank sensors and sludge buildup. We have used it for over a year and it is definitely great at reducing odor. We haven't noticed any appreciable difference in erroneous tank readings and I assume build ups are being handled. Sometimes I wish they put inspection windows in the holding tanks. After 40+ years of RVing this product aooears to be as good or better than any we have used before.

We bought a destination trailer to live in while building our new home. The trailer came with a sample bottle of this TankTechRX product for us to use. We are new to RV living and knew nothing about black tank maintenance. Rookie or not, it won’t take you long to figure out what works and what doesn’t work, especially when you get foul odors every time you flush. After flushing out our black tank for the first time, we decided to try other tank products without success and ordered more TankTechRX. We are TankTechRX customers as long as we own this trailer. Two (2) ounces is all you need per treatment cycle. No fuss, no mess, no smell.
