Lights are probably a culprit but they're not the only one that contribute to a power bill sticker shock. Your choice in pumps can make a huge difference. Powerheads and Tunze's are peanuts to run, but something like a Little Giant or two can add up. Heaven help you if you run a hot tub pump.
I don't know what to say. Unfortunately it's not a cheap hobby. If it's any consolation, we all have spouses who get irritated by the power bills.
Just ask mine. One piece of advice: be prepared to run when the expletives start.
I'm with Jonathan, if my bill comes in at <$230, I go out to dinner to celebrate. And buy a biiiiig steak or something.
