Hi,
We just lost power for 24 hours as well so I can tell you what I did. We didn't have a battery backup or generator and Home Depot was already closed. From what people had posted I thought I was looking at a disaster after a few hours so I didn't think pouring the water was going to be enough. I believed that Oxygen, temperature, and circulation were the things to focus on. At least hourly I used a battery powered milk frother I have to create bubbles for a few minutes. Before I thought of the frother I was going to use a manual egg beater to do the same thing. I don't have a mechanical thermometer so I wasn't sure the temperature but the water felt cool. I started filling large bottles with boiled water from our gas stove, made sure they wouldn't leak, and floated them in the water while using the frother to slightly circulate the water. This worked well but I should have been more aggressive since the temperature got much lower than I realized - 71.8 degrees.
By the next morning (after 12 hours) everything appeared alive and I kept hearing from DWP that the power would come back on so I didn't buy a generator, even after Home Depot opened. It turned out that the power would be off anther 12 hours. When the power came back everything was alive and looked ok. Weirdly my Acros had really good PE. It's been 15 hours since the power came back and one Acro is RTNing but everything else looks fine.
I hope your power comes back soon and everything ends up fine!
