After following this all day, I couldn't take it anymore so I caved in and I just ordered the battery backup for my 2 vortech MP10's. Ecotech claims that the battery can run the mp10 for over 30 hours at a low setting (should be enough to keep my corals happy). So If I can 2 MP10's I should get at least 12 hours out of the battery which I think is pretty good since I never really use power for more then 2 or 3 hours max. Good luck everyone that has lost power today. Hope everything works out well.
