Battery Powered Air Pumps

[TheTodd]

I purchased two today just in case power goes out at some point. Does anyone have ideas on how many should be used for a 60g cube and a standard 240g?

I used 1 in each of my tanks when the power went out for several days. My tanks range from 30-220 gallons, didn't lose any fish with 1 pump on each tank.
