hey everybody just wanted to say how important it is to have a back-up plan when you lose electricity. we had a huge snow storm (i live near harrisburg, pa) and our electricity went off for 7 hours! my aquarium lost 3 degrees in about 1/2 hour until i got the generator working! i really don't know what i would have done without it. we had no heat in the house and the inside temp went down to 63 degrees before our power was restored it's supposed to go down to 27 tonight so i'm glad we have power although our lights have flickered twice since then. more bad weather is possible throughout the winter so if you can i'd recommend a generator if at all possible. i know it saved my fish.
