From what I understand, you can get one of the computer APC battery backup systems and just hook your heater and one of your pumps up to it. They're only like $30-$40 and should run for at least a few hours.
Me, I just make sure when the pumps go off, nothing overflows, and I have an air hose near by...and good lungs.
Fortunately I work for a place that has several small Honda generators that I use when I am out splicing fiber optic cable in the middle of no where. I get to keep on in my garage at all times unless I'm going out of town. I have thought about a UPS but I want something that will sustain at least 1 heater up here in the GWN along with at least my return from the sump as well, and with outages lasting several hours to a full day around here... It is near the top of my new ordering list however.
HOW MUCH IS A HONDA generator?
think we will look into the apc backup,lol maybe a few .
Going tonight to get a huge rubbermaid tub ,to catch the overflow lol
During the recent hurricanes, I used a handful of battery-operated air pumps. Seeing as how it was already warm, etc. during the summer, I had to worry about keeping it cool. It worked though and I had zero losses, even after a week without power.
I use an APC battery (1400w) as well as have a backup generator in the garage. Only had to start up the generator once to save fish tanks.
When your initially setting up your tank though I would pull the power at least 10x and watch carefully to see how everything works. Repair as needed. There is always something that gets overlooked (at least in my case there was) and a flood ensues. Check and double check your overflows.. back syphon issues.. pump restarts.. things like that.
I have blankets if it's cold, bags of ice if it's hot and a piece of hose and my lungs for air! We don't get too many powercuts here and I've only ever had one powercut that lasted 24hrs and everything was fine.
