Backup power units?

[justinl]

i use an APC for my tank but i only run one powerhead on backup power. the other things i put on surge protection. I don't see the need for 24/7 heating as the heater will really suck up power fast. water movement is more important imo. besides, you can just put hot water in a water bottles and float them if the outage is long. or just plug in/out the heater every half hour or so.
