Review: Sensor for black tank and cleans well with smell - Best stuff to clear black tank censors
Review: Works very well! - My Black Water tank sensor was not reading. I put this product in the empty tank, and filled 3/4 full with water. Within two hours, sensor started reading, looks to be accurate. Going to drive and let the cleaner slosh around anyway, but seems to do what it says--clean the sensors!

Have used this product several times as directed and it seems to help clear the black tank, but not completely. It could be a bad or stuck sensor that will not clear.
