Yes the black spots are at the top of the bowl, 2 to 3 inches or more
above
the water line and eventually spreads to the underside of the seat, only
if
I do nothing (like when I was gone for 2 weeks), will the black stuff
spread
to below the water line -- I came home and my wife had an all black toilet
bowl.



Don't you all flush regularly?
