Battery backup air pump

[CNDReef]

What battery operated air pump would you recommend in case of a power outage? How long will it last ? How many per gallon?

Any battery-powered air pump would be useful in an emergency. Most are used for fishermen who want to keep their fish alive. I would say that 1 air pump per 20 gallons would be a rough estimate. You can also get a solar powered air pump if you live in a relatively sunny area.

I ordered a pen plax b11
It turns on when the ac power is interrupted.
Also got told they’re good for 25-30gallons
Ty for the reply
