I also never rely on the sensors. I listen to the black tank when flushing and when it sounds gurgle and may blow a bubble when flushing I dump. Average is 5 days. Grey tanks fill fast from the kitchen due to dishes etc. Leave them open
I don't know if I would want to see a bubble... sounds like the start of trouble brewing.
On the other hand I don't know all that much about the black tank.
The black tank never been full when I dump. I do make sure it's at lease 2/3 full which takes a lot of effort with longer flushing since I camp solo and usually only 2-4 nights. Now the gray tank is another matter - no problem getting that tank filled completely.
Great choice for "Living within my means" and camping for one...
