I know it's a little too little and a little too late, but future reference for those of you caught in a power outage. If you don't have batteries, and you are worried about oxygenating your water, Hydrogen Peroxide works great. In a pinch... some hobbyists have had success using 3% Hydrogen Peroxide (from the drugstore) to instantly increase dissolved oxygen. The dose is about one ounce per 25 gallons, more or less, so to speak. It should be added near the bottom of the aquarium (a sprayer bottle would be ideal) and distributed quickly around the tank so fish do not come into contact with the concentrated form. This is a risky treatment that should only be attempted if it is obvious that fish will begin dying soon from lack of oxygen.
