UPS power backup for aquarium - what do you use?

[Wooki]

For those that have SW reef or fish only setups, what are you using for power backup in case of a power failure.  We had a 3 hour power failure a few weeks ago that I was home for and was able to keep the tank circulation up manually. I have a battery powered air pump with an air stone that kicks in when the power goes out, but this doesn't seem like it will keep the whole tank oxygenated when the fish stop swimming (in the dark).

I have a bunch of corals (lots of LPS, some SPS) and about 10 fish (A few big active tangs).
I'm thinking about getting a computer UPS just to provide power backup to a few of the Koralia powerheads to keep the circulation and oxygen up in case I'm not home during the next power outage.

I'm wondering what people are using for their power backups for their reef aquariums?

Thanks

I personally have a generator that will take care of the system incase of any long power failure.  Computer Battery Backup is  nice to have for powerheads, thats for sure.

I had posted about this not too long ago... I have a computer UPS battery backup that kept my powerheads and heater running for about 4hrs and could probably have gone lots longer.

The only think I wasn't keen on, that I'm sure (might) be configurable via software is the constant "BEEP!" every 2 or 3 minutes the power was off.

Simple trick I used to do, cut the wires to the speaker   haha.

Thanks.  How many VoltAmps is your UPS rated at?
