Welcome to the forum from me too!

Nope, don't trust the sensors. They get grime and foreign matter stuck on them and they are false nearly all the time. We dump the galley twice a week and the gray stays open all the time in the summer. The black gets dumped when the toilet burps. Then the black tank gets the wash of its life, but the sensors still read full. I've never had sensors that worked correctly after the first month or so of use.

On edit: Calgon is a popular additive to the tanks. We cannot get Calgon in Alaska, so we use Cascade. They both help by keeping the tank slick so things can flow out better.
