What happens when power goes out???

[Ti_CLaD]

I own a 26gallons tank with one F8 puffer... We're having a situation in Quebec, Canada with ice storms, we've received icy rain, roughly ¾" thick on branches I've seen... Villages to the south of my home and to the east had power outrage for a few days now and are starting to be hooked up... I've been lucky, power has cut often but never exceeding 30seconds... But lost internet for 4days, better that than power I think...

But that reminded me that in 1998 we've loss power for 10 days and some of my friends in other towns had lost it for 23+days... What would happen to the fish??? How long could it go without reoxygenizing (is this even a word???) the water??? I can have access to a generator, but could have to share if my father happens to need it too...

Any alternative possible??? Like mixing the water by repouring it in itself a few times for a certain amount a time to keep it "ok" for some other period of time??? How to test oxygen in water??? I'd hate to see the fish die because power went out for a long period of time... It stopped raining for 1½day now and not calling anymore, so unless a branch would break on wires we should be in the clear!!!

I did that all night with Hubby for 9 tanks. We bought a generator after that one...
There are smaller battery backup pumps.

I've lost power before in the winter and wrapped the tanks with comforters...Then, because I have natural gas and city water, I filled 3-4 2ltr soda bottles with hot tap water and placed them together alongside the front glass, under the comforters. Worked quite well...Just keep roatating the bottles out.

without a generator - all of the above
with a generator - fish are happy, all problems solved including house lighting & heating, TV, stereo, cooking, life is good!

we were lucky enough to miss that part of the storm being north of Montreal. Last year we were out of power for 40ish hours and bought a small generator to run our tanks. puffer ghoti and I traded 4 hour night shifts to keep the gen running. We are hoping to buy a bigger generator so we can run more tanks without switching them out every couple of hours as well as being able to provide some hot food/drinks. We have 2 wood burning fires so that helped keep temps up in the house.
