I found a battery pump that says it turns on automatically if plugged in when power goes off. If so , that would be great for us long distance/boarding style fishkeepers.
Thing is when the power goes out, it's usually too dangerious to drive to the fish, because there te ds to be a weather problem that made the power go out in the first place.
