UPS battery backup question

[hillegom]

I think one of the best things you can do in the case of a power outage is to create water movement, which is what u wanted to do with that 5W pump.
You might want to think about running a battery powered air pump.
Mine is plugged into 120V, the wall outlet. When the power goes out, the air pump starts automatically. D batteries run it for at least 24 hrs.
The air line goes under a rock.
