I agree with a drain blockage of some sort.

FWIW (and the adjustment I didn't do on my first sump) I always block the drain and insure the sump runs dry before the upper container (usually the display) floods.

looks like when you clean the drier vent you should also clean the overflow.

That's amazing, and I thought my first tank had a bad case of bristal worms. I wonder what quality of cleaning service they were providing.
