Backup battery

[Perthegallon]

Okay so I’m getting ready for the winter in a few months and I know my power will go out maybe 1 or two times I may have a power shortage at around 12 hours at most in one day. My tank runs not much electricity I really just need the return pump and heater to stay on about 100 watts to keep both of those going at the same time is there anything I can get out there that I just put d battery’s in and can just change it out when it runs low or anything else anyone suggest I wasn’t a big fan of ups unitsy and didn’t want a generator since they cost a lot

Get a cheap battery powered air pump used for fishing. They'll cost around $10 and they'll run as long as you have batteries for them. Aeration should be good enough to get you through most failures.

And don't worry about a heater. You'll need a huge battery bank to run even a 100W heater for a substantial amount of time.
