Yes. It will work in the event of a power outage. I would just watch the
pond to see when the fish say they are needing more before dosing again. It
can be repeated as many times as needed, but do not overdose, since peroxide
is a sterilant and can burn the fish in overdoses.

would this work in the event of a power failure? how often can you add
hydrogen peroxide?
