Those battery air pumps are a great idea!
I also used automatic ones that switch over to battery power fails.
One other idea that we used in our LFS during the LA, CA rolling
blackouts was a RV battery (or two in parallel) with a Modified sine
wave inverter, this also ran our electronics during this time.
===================
That would be a ideal for a hobbyist with a load of tanks. We have the
type fishermen use to keep their bait alive. They run for a long time on
batter power. They cost around $5 each and have lasted for years.

I have been buying them from a chinese supplier.
They cost me around $2 Aus each if I get a box of 25
they do last for quite a while too.
If you have an inverter you can run off a car you can power an entire fish
room.
Most of my setups run off one large air pump
so this has been my panic solution up until now.

I like the idea of a seperate redundency tho.
