Power outages-What do you do?

[RTRJR]

Don't overstock. The multi-day power outage we had last, we ran the fireplace 24/7, and have a smallish portable generator which ran a couple of radiant heaters in the pool room/tank room. I lost one tank of shrimp, no fish, not even a small group of rainbow fry. The biofilters were (SOP for me) dumped into shallow trays of aged water to avoid anoxia. No other special tank care.

If it's just a problem with still water for more than a day and not temperature I take a couple of 5 gallon buckets, siphon some water out and dump it back and forth between buckets a few times then dump it back into the tank. I do this a couple times for each large tank 2 or 3 times a day, I have not lost a fish yet. Small tanks actually usually have enough surface area that you just need to swish the water around it the tank a bit to keep from having problems. Temperature is another beast altogether, but as long as it stays above 60 and below 85 in the basement I don't have any problems.
