If my power went out, I'd just power my return pump and skimmer. Corals can go a couple of days with no lights. Don't forget about your freezer so that your fish food can stay frozen.
Sal I think it's been postponed to the first week of October and it will be from 10:30 pm Sunday to 6:30 am Monday. I logged on Edison website and typed in the outage number and it's said it's been postponed. So that means it's only about 8 hours or less now.
