Just as promised!!
We recently used this on our 5th Wheel black tank and cannot say enough good stuff about it!! Our tank sensors began reading FULL after our second or third trip, even with excessive rinsing and cleaning after each trip. We are in our second year of our ownership and travel just accepted the fact that our sensors (as most complain about) would never work again. So we followed the directions on the bottle. Filled our black tank (49 gallon tank) added the bottle of cleaner to the tank and parked it for about 2 weeks (in between trips). We dumped our tanks when we arrived at our next campground, dumped our tank and rinsed well. No odor, no issues and best thing yet? Our sensors once again read accurately!!! It's a little thing, but it's a great feeling! We use a few of the Unique brand cleaners and treatments and have been thrilled with the ease of use, quality and performance of them. Good size bottles and I feel the price is well worth the results you receive. Nice to have products that are seal and tank friendly and safe to let sit in the tank for extended period if needed. Highly recommend this deep cleaner and all of the Unique products for care and maintenance of our rig!

Works!!
I was skeptical but it worked GREAT! We had a smell coming from the toilet. I left this in for an entire week then flushed the tank out twice and the smell was gone. Highly recommend!!

Outcome not definitive
Left in tank for 4 days following directions. Don't really think it did much. We flushed before filling tank with this product to give it best opportunity. We had no issues but rather preventive measure. We then flushed tank several times and finally WAND cleaned tank through toilet after several drain and refills. Did it loosen, and to this I respond, maybe! A full tank of clean water over time will also loosen things up also. We are by no means experts but with 30 years of RV experience think we have a pretty good knowledge base to make a determination. Maybe if we had towed with the product in tank we would have a different outcome as agitation may help. Will we buy again..... I think not..... but that is only one persons opinion. Your outcome may be different. We are relentless on flushing tanks as RV is no longer towed and don't want black tank problems. This clean was not done in response to problems but rather part of routine.

Works Great
This stuff does the trick for RV Black Tank Maintenance. Love the whole line this company offers and use it exclusively over the past 4 years of camper ownership. Great value for the money, doesn't smell bad & gets the job done. Just follow the instructions.

It worked great
This removed the "pyramid" from my black tank. I filled tank and added full bottle at home two days before a trip. Drove and dumped at the campsite. Shocking how much "stuff " came out of what was supposed to be an empty tank. Tank light back to E
