I have a 150 watt heater, a 75 watt heater and a 50 watt heater. My
lighting consists of 4 T8 bulbs 32 watts each and 1 small 18 watt reptile
light. All I can think is that one of my heaters is shorting out and
causing all this extra electricity use. It doesn't make sense.

Something non-fish? Perhaps an electric kettle? Tumble dryer? Storage
heater?
