Rated 5 out of 5 by from Tank indicator light on when empty I had problems with my 1/3 full light staying on in my black water tank after flushing it out. I used a pack tank blaster overnight and about a 100 mile trip to the campground in the morning. I dumped the black water tank and flushed it and was amazed how much heavy crud came out till it ran clean. It cleared an apparent buildup that my normal flushing wasn’t cleaning. Light has been out since when empty. I’ll use it next time it happens great stuff.

Rated 3 out of 5 by from Disappointing results, not the answer for fouled up tank sensors I've never been impressed with any of these enzymatic products or mechanical tank rinsers to clean my black holding tank sensors, which have always read full or 2/3. I ordered Tank Blaster right before I ordered the SeeLevel II tank monitoring system. They arrived together. After installing the SeeLevel (a difficult task in my coach), I proceeded to use the Tank Blaster. Filling a holding tank when it's empty yet reading full can be a problem since you won't know when it's full. Fortunately, the SeeLevel helped with that. It's very accurate. I followed the instructions on the Tank Blaster package. I let it sit overnight and then drained and rinsed the holding tank. It went from reading 2/3 full before cleaning to 1/3 full. I can often get that kind of temporary improvement with just rinsing the tank. The SeeLevel monitor said it was empty again. The Tank Blaster package comes with 4 envelopes of chemicals, so I could do it 3 more times. The package says that it might not work the 1st time, that repeated treatments might be needed. And that may be the case. But that would mean draining the tank, filling it up to the top, adding the chemicals, waiting overnight, draining the tank the next day, rinsing it out again 4 times! That's a lot of hours to put in to only have those sensors foul up again in the near future...

Rated 1 out of 5 by from Ineffective as advertised Used all four bags following directions each time with no benefit or change in sensor readings. Bought unit used so no clue how previous owners maintained the tank.

Rated 1 out of 5 by from I would not buy this product again. The pack I used didn't do anything no foam nothing.

How Does It Work?

Does the RV need motion for product to clean?
