Hi everyone. I was wondering what item for your tank uses the most electricity. I remember when I first started a larger tank (100 gallon) my mom almost had a heart attack because our electricity bill skyrocketed. I'm about to start a 240gallon tank but I don't want my wife to kill me when the energy bill comes. I'm thinking that my heaters would use the most energy. If they do, I'm probably going to get fish that won't require them, like fancy goldfish. My house is pretty well insulated so the temperature in the house is actually pretty comfortable. Anyone have any ideas regarding high energy usage? The Doctor
