I can run for 2 days with no power on my battery backups to the point where, in the winter falling tank temperatures might be the second greatest issue. That is another discussion since heaters draw so much power it wouldn't be feasible on battery backup, it would be generator time for something with that kind of load.

Yup, totally agree. With our big outage here in the lower mainland just over a month ago, I got caught without my battery/inverter backups available, and lost 4 fish due to O2 deprivation. Have made it through several power outages (and longer ones) in the past, and just kept a couple powerheads going in each tank, and never a problem. They take very little power. Even had enough battery power to turn on the heater periodically to keep the water from cooling too much. Did not need a generator (although had one of those available too, for the freezer).
