ValterraV23128 Pure Power Blue Waste Digester and Odor Eliminator - 128-Ounce Bottle

The price of this huge bottle was excellent. I use it in my RV and it works great and it smells great.

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.

We have been using this product for years. Very satisfied with it. Does what it is supposed to do.

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.

I had a guy out fixing my roof on my RV and mention if he new of a product that would clean my black water tank. He told me about this product. I have used it and it clean it nicely. No more bad smell all the time. This product smells very good as well. He Suggest I poor a whole bottle in and let it sit for 24 hours. As bad as the black water tank was he said I may have to do it more than once. So I did it, but I let the first treatment (full 32 ounce bottle) hold for 3 days and the 2nd treatment (full 32 ounce bottle) for 3 days and the 3rd treatment (1/2 of the 32 ounce bottle) for 24 hours. And all was good and I mean no more bad smell coming from the black water tank. He said this would work on the grey water tank as well. Mine didn't needed it yet but when it does I will use this product.

My husband and I were recommended to this product by a master RV mechanic. This stuff works wonders. When we get every order in the mail, it is packaged well and we have yet to experience any leaking during shipping. We love the fact that the container is labeled with OZ and instructions so we know exactly how much we need to use in our black and grey tanks.

This product is easy to use and leaves the tank odor free with a clean scent. I wouldn't use anything else.

Product works as described. Seems to break down waste well and has a pleasant not overpowering smell!

I don't normally write reviews however in this case I had to. We have 2 outhouses installed at our flying clubs field. They were a horrible mess. The smell was bad inside and the flies were unbearable.After a thorough cleaning and disinfecting we put a half of the 128oz jug down each hole and added some water to get things going. That was 2 months ago. It has been a very hot summer and there is no smell and 0 flies!! There is still a faint mint scent from the product. We will be getting more to add shortly and will continue to do this process every 2-3 months from April until November.

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.

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.

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.
