Power is going to be down for approx 2 hours

So on Tuesday I am having my battery back up replaced, and everything that is connected to my aquarium is connected to that. I don’t think two hours itself will be a big deal, and I’ll be running a uv sterilizer on a long extension from another room anyway, but I was wondering if anyone had any advice for what to keep ready “in case” something goes wrong.

Unless you are worried about temperature swings...i would say just a bubbler and air stone that you can run off an outlet.

I keep one of these on hand just in case and it worked well the one time I had to rely on it. It holds a charge for a long time as well. It has a nice feature where it will automatically kick on when it detects power loss.

2 hours is nothing to worry about and uv would be the last thing I would run an extension cord for why not your return pump or a powerhead

A power head is sufficient. Heater only if necessary

The only thing that actually needs to be running during that short timespan is your powerheads. Run an extension cord and power strip to your tank and plug those in there until the work is complete.

While not required, also plugging in your lights, return pump, skimmer, and one heater will cause even less stress during this period.

UV is not needed at all during this period.
