If temperature isn’t an issue I let my tanks go 4 hours b4 connecting back to generator. In between hook ups I scoop tank water and pour it back in from a foot above to add oxygen to the water

Besides getting them for your tank also get one for your sump . Their are battery backups that you can hook your pumps up to . I use the ecotech battery hooked up to their pumps

When Michael hit we lost power for almost a week. I somehow made it through without running any of my tanks on a generator or using battery operated bubblers. Would have killed for bubblers. Lol. (Why I have so many now.) Didn’t lose anything, but these were all freshwater tanks. Aerate the heck out of the water like @Fishnut said, and hook up the generator if you need a break.
