I'm just putting my experience out there, as a warning to others, to
make sure your filter is running immediately after power outages. I
wonder of others have experienced this problem.
========================
I've had a few Aquaclears to not start after an outage but no harm came
to the impeller well, the motor or the impeller itself. After cleaning
the slime off the impeller magnet, and the well itself - they'd start
right up again. My Fluval always started after a power outage.

This has been my experience as well (no damage), but I guess 30 hours
with extra heat from the magnetic field, and no cooling water to flow
past caused the hot spot to warp the plastic, further seizing the
impeller.

This is worrisome for office tanks which are left alone for the weekend,
and I don't see many practical preventatives (monitor electrical current
to interrupt power, monitor water flow to interrupt power or clean
impeller well religiously). I suspect different filters will have
different susceptibilities to this failure mode.

I have heard/seen this before (rarely) so I too am curious on what
equipment this has been seen before.
