My black tank sensors work most of the time but when they don't, it's annoying. I'm going to give this GEO Method a try. I like the fact that the Calgon water softener [don't use fabric softener] coupled with Dawn dishing washing detergent, lubes the tank wall sides and sensors. Got some Calgon 32oz size at Walmart for $5. Gonna do the grey tank as well. I'll do it once to see if the sensors read correctly and when there not, I'll add some more.
