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.

This stuff WORKS!!...even on a stubborn Pyramid Plug!We had a problem...a big, messy problem. Bought a used RV and you never know how the previous owner used the tank, how well they cleaned it, etc. Our problem showed up while camping...stopped up toilet pipe. Apparently we had what is called a Pyramid Plug, which totally clogged the pipe and wouldn't let water from toilet drain into tank. Hubby tried using a plumbing snake with no results. So research led me to the Tank Tech RX site where they told how to make a tool from hardware store supplies to put a hole in the clog for drainage. While this was a good temporary fix, the problem plug was still there and would rear its ugly head if we didn't kill the monster. I will say that in my desperation I put a dose of the minty smelling chemical holding tank granules that I had in stock in the RV in hopes that during the trip home and subsequent (3 week) storage it'd work to clear the clog. That didn't happen. So I ordered TankTechsRX, put 2 ounces in, filled the tank to about 2/3rds, and let it sit for 3 weeks. Result? CLOG GONE!! A whole bucket of water dumped into the toilet doesn't shoot back up into the room. (a sign that there is a clog or near-clog). And the tank sensor is reading correctly for the first time since we've owned this camper. We've been through 5 day camping trip of using the toilet for both liquids and solids and Angel Soft toilet tissue and have had no problems whatsoever! Kudos to TTRX for not only working so well, but clearing up a definite plug problem. You gotta love natural products that work so well...you go, you tiny probiotics!!

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.
