Power Outages?

[spencerC]

Okay, so let's say there's a power outage.
I'm sure it varies from tank to tank,
but personally I (will, in a week) have a 75 gallon FOWLR, that will likely expand soon to have corals.

Without backup power, how long do i have before stuff starts to go downhill in the tank?

I'm wondering if i would be okay getting one of those big camping battery things from canadian tire to at least plug in the important stuff til the power comes back on.
But ealier this year the power was out for effing 30 hours at my house cause of a wind storm...
I don't think the battery would last that long...

How much is it to invest in a back-up system?
My dad is an eletrical salesman and i think he would be able to install it and what not i believe.
