DTE is saying 9:30-11:00 pm tonight for us....
about the generator, yes, they are nearly a must have for reef keeping.
we have a box where you can control everything in the house, if you want to run it from the power line or the generator just by flicking a switch. as for the generator just plugs into the house. super convenient. would recommend this to everyone as it takes me about 5 min to get the generator from the barn, start it, plug it in and switch the fridge and aquariums to the generator.
