Power Failure and Cannister Filters

I was without power for almost 30 hours. It started at 10 am and I made sure that my cannister was unplugged last night because I remembered someone at the latest aquarium society meeting mentioning that their filter went anerobic after eight hours without power. Once the power was on again I went into the basement to flush out the cannister. Wow! The odor was overpowering. I took the cannister outside and rinsed all of the hardware with bleach, rinsed the media for baking at a later date when the wife isn't around and made trip to the local pet shop to get some fresh media to start over again.

I don't know if I needed to get that extreme but I thought it may be necessary. Has anyone else had any experiences (good or bad) with their cannister filter after power failures?

If I expect a cannister filter to be off for more than an hour or so I would disconnect it from the tank and drain it, but not open it. This gets plenty of air (read oxygen) into it that will keep the aerobic bacteria alive as long as the media is still wet, which it will be for quite a while if the canniser is kept closed.

They can survive for a lot longer in a moist environment like this than if kept submerged in a still body of water, where they will quickly deplete the available oxgyen and then start dying.

Hurricane passed nearby a couple of years ago. We were worst off in the area - power poles tilted over by a falling tree. Without power for 28 hours. All I did was aerate the water in the tank a little using a bucket and dropping water from a few inches up - did this every couple of hours. No fish losses, no canister filter issues (never even unplugged it or think to clean it). Maybe I was lucky . . .
