Well, I am from california and worry constantly about our stupid power situation. My power has gone out on many occasions and everyone is fine, (I did loose a blue hippo tang) but the power went off and on 3 times in the same day. Now, when the power goes out, I call the electric company and find out how long they expect the power to be out, and if it isn't more than 2 hours, I just leave it alone but, if it is more than 2 hours, I unplug the pumps and skimmer oh, and the lights just to be safe. I am getting battery powered pumps and a converter for my boat battery so I can use that for long periods. Right now, a generator isn't in my budget. Also, doing the water change helps too. Good luck.
