How long would one of those last? I checked into one to drive the basics for my
125 gallon (mainly the heaters), and the ones I saw wouldn't last long. The
local electric company ran a "rolling blackout" one winter, and I remember
watching the temperature fall in my tank and being unable to do anything.
Not a good feeling.

Interesting...
What temperature drops have you observed and how fast ?
How long this blackout usually lasted ?

The idea with backup power is NOT ment for the heaters - they consume
too much power and the battery will exhaust very quickly...
They are ment to sustain water movement/aeration becuse the lack of
oxygen will kill your animals much faster than a slow temperature drop.
