Valterra V23017 'Pure Power Blue' Waste Digester and Odor Eliminator - 4 oz. Bottle, (Pack of 6)

I’ve used this in my black and veg Ray tanks for several years. I live and camp in the desert SW, and it gets HOT here. This product does the job! No odor in the trailer even with nearly full tanks in July. I have one of the smaller bottles with the built in 2 oz measure and I refill with this. I highly recommend this product. Just remember to flush your tanks well and add 2 oz and some water after each trip.

This is some good stuff. Works great and smells good too. Totally recommend. Easy to use

I used this product for the first season and a half with my travel trailer. When it ran out, my wife bought some pods that were supposed to do the same job. NOT EVEN CLOSE. After three months of using the pods, sewer smells were leaking into the camper. I bought another gallon of this, and with two uses, all smells stopped.

I've tried maybe not all of them but some of what are supposed to be the best. We live full time in a 5th wheel with two bathrooms and it gets pretty hot down south. Some of the others dissolve stuff pretty well but within three days winter and summer, the stank is there again. While I do use a little more than what they suggested especially in hot weather, I'm good about a week with this stuff which makes me happy and if I'm dumping at 3/4 full, there's little to no smell at all. My only disappointment is that just about every time I've gone to buy it ........ it gets more expensive. That's one reason why I switched from what many say is the very best to this. The best was wayyyy too expensive. Seems like this has gone up 5 to 6 dollars more in just a few months. Bought 128 ounces this time to cut down on cost but if the price keeps going up I'll have to start my search again. I hope that doesn't happen.

This works very well in my trailer's grey and black water tanks

Kept the portable camping toilet, smell free for 4 days.

Excellent for gray and black tanks!

We had a clogged RV Black Tank and the sensors had been incorrect on it since we aquired it and the sensors were also incorrect on the gray tank as well. We stopped and had our tank pumped out by an actual Septic Pumpout Service and to no avail the whoole ride we were still smelling grossness. So then we pulled over at a RV supply store and bought a tank wand that squirts high pressured water like a crazy sprinkler inside and some tissue digester. That entire weekend we used the tissue digester and even used it and ice on the ride home after dumping thinking it would clean muck up and then dumped the tank when we got home and still smelt grossness the whole ride and still had sensors blocked up not knowing what the true levels were at. SOOOOOO - I went online and found a review that a rv tester guy said this stuff was the best around and had a video of the regualr stuff vs this stuff and regular charmin toilet tissue in a cup.... the other stuff didnt break down the tissue but this stuff broke down the tissue into particles in a few minutes!!! I was convinced I had to buy it - so by the time we went on another trip the directions said to use 2 oz per gal I think - well um no I used almost a half of a bottle by the time we were done tih that trip because I poured some into the "empty" tank on our way to where we were going and figured it would swish around and get it deteriorated and we were ri9ght it was swishing so much it started to stink again so i would pour more and more power blue down the toilets everytime it stunk lol - well that goes to tell you that tank wasnt empty - we pulled over before we got to where we were camping at liquid masses of the nastiest water i have seen came out of that tank and poured a little in the gray tank also to see if i could get crud off sensrors to read right and whtchya know all the sensors were reading right - tanks were finally truly empty for the first time since we have ownbed it for an entire year and the entire trip there we were off grid and didnt smell a stinky drop and could smell the great freshness from power blue!!! I am going to use it correctly this time so it will last longer now that we have finally fixed the major clog we have had until we found this miracle!!!! Thank you internet rv tester product guy because of your video we found the miracle to getting rid of stinky, clogged rv tanks!!!!! Oh yea and my husband thought I was going to burn like oven cleaner when i got alot of it on me from hitting a bump while pouring it into the toilet when he was driving but not a bit - it wiped right off my skin didnt stain didnt burn and even washed out of bath floor mats no problem no staining at all~~~

Use for grey water tank, reduces odours effectively

I am constantly buying this stuff for my RV and my home. First, for the RV, it's great for killing the smell in both they grey and the black tanks. It only takes a little bit, and it works like a charm. At the beginning of the season, I usually buy a smaller bottle and pour the entire contents into my black tank, then fill the tank with water and drive around for a bit to mix it all together. Then I let it sit for a day and dump it after that. It clears everything off of the sensors etc in the black tank.Secondly, for my house, any slow drain or clogged drain can be fixed with this stuff. Simply pour in about 4 oz and let it sit for a few hours. It's environmentally friendly and wont destroy your pipes like the commercial drain cleaners. It's never let me down. I've had problems with my drains in the past and when the plumber comes out, they used to sell me a liquid that they told me to put a cap-full into my sink drain once a week to remove the build-up. It was $64 for a 32oz bottle, but now that I can buy a 64 oz bottle of this stuff for $32, I no longer need to buy from the plumber. And this stuff works and smells better.Even if you don't own an RV, buy some of this for around your house. It doesn't hurt to add it into your bathroom sink and let it sit over night in the drain just to clear out all the gunk that builds up. I've recommended this product to numerous people.

Purchased a jug, 128oz of Power Blue.1-price is good if you go by the directions of 2oz/40 gal. tank. Works out to 64 tanks, compare that to other single drop ins.2-I've left Power Blue in the original container under the sink in the cabinet. We havent noticed any over powering smell as many have said here.3-I've only had Power Blue long enough to do one dump of all 3 tanks. No odour at all from the any tank. Toilet paper seem to be more pulpy like.4-Havent seen any difference on the gauges but then again this was only my first dump.In a nut shell I will buy another jug of Power Blue. Its definitely no worse than any other additive I've tried, may even be a touch betterBut the for the price (use as directed) its only 54¢ per tank (128÷2=64 tanks)I purchased this when it was $38.

I'm on my second bottle and it works well meaning it does what it's supposed to do and does it well. The scent is a bit strong when pouring into your toilet but disappears relatively quickly. Bottom line is that it keeps the tank clean.Recommended.

Great smell, I've never had the revered sewage smell in an the years of using this brand in any of our RVs. The large bottle lasts a long time of you use the correct amounts.
