I would think the bacteria would start to die that many hours without
a fresh flow of oxygen rich water. I personally wouldn't do that.

The bacteria certainly wouldn't die. Nitrosomonas and nitrobacter bacteria
are a lot more resilient than people give credit.

What would happen is that the lack of circulation would prevent the
bacteria from doing its job properly. The low levels of dissolved O2
combined with the high concentration of ammonia present by morning would
mean it would take time for it to be processed out of the system once the
filter is switched back on.

The pH would being to climb the moment circulation resumes as all the
built-up CO2 is forced out of the system, making the lingering ammonia all
the more dangerous.

This may be true but many filters, like the ACs have a deep 2 sponge well
that would quickly go anaerobic under the sponges after several hours.
Perhaps the shape and depth of the filtering material would make the
difference. I know when we lose power at night and I get them started again
come morning, I can sometimes smell a funky odor they don't emit when not
stopped for who knows how many hours. For some reason ACs don't always start
by themselves when the power comes back on.

That doesn't sound too good..... :-(

It's just not a good idea to shut them off.

Hypoxia won't directly kill off aerobic bacteria, it simply prevents them
from obtaining food through nitrification. The hypoxic conditions need to
persist for an extended period of time for the nitrifying bacteria to begin
to die off rapidly due to, essentially, starvation.

The odor you are smelling could be a lot of things, the least of which are
dead nitrosomonos. My first guess would be sulfuric gasses produced by
anaerobic bacteria.

This is generally due to some force of resistance on the impeller, usually
friction between the impeller and the impeller shaft or the impeller blades
and the plastic guard which sits above it. If you gently touch the
impeller bade with a plyable object that won't do damage to the plastic
blades, it should spring to life.

============================
That's exactly what I do! :-) I move the intake over and give the impeller
blades a little nudge with a piece of plastic from a Q-tip. I have noticed
if there's a lot of slime on the impeller and impeller walls they wont start
themselves either.

This problem happens a lot less often if you regularly clean the impeller,
shaft, and motor well.

My AC motor cleaning kit consists of a pipe cleaner brush and an old tooth
brush. I remove the impeller and clean it with the tooth brush, then yank
out the impeller shaft with a pair of pliers and clean it with a soft rag
or paper towel, then I clean the inside of the motor well with the pipe
cleaner brush. I suppose a very fine pipe cleaner would work well to clean
the inside of the impeller magnet and remove any metallic fray from the
inside of the magnet, but I've never found it necessary to spend the time
trying to obtain one fine enough to fit.

Cleaning the motor regularly also cuts down on the wear and the amount of
noise the AC filters tend to make after operating for a few months.

You're right. I should do them more often. I squeeze out the sponges every
week or so but only clean the impellers/wells once a month.

I'm not that particular. I also use an old toothbrush to clean the magnet
and blades, but a Q-tip to do the well. I don't remove the pin or shaft.

I don't doubt that a bit. I've been fortunate in that only one of my ACs
has an irritating grumble. It's in the sunroom so we're not bothered by the
sound.

I do partial water changes twice weekly. I look at the water flow out
of the filter. Slow flow is the signal to clean the filter media. If
the flow is still slow after changing the media, I know I need to
clean the impeller, magnet and motor well. Good time to check the
intake plumbing as well.
