I buy the cheapest power strips I can find which come in packs of 2 for $3.99 at Walmart. About the only thing that would be a power hog on an aquarium setup would be special reef lighting, but for me Im satisfies with using only 0.25 watts per gallon. The biggest hog on my 244 tank is my 300 watt heater which in AZ hardly get used (today's temp 85F). So in total Im using about 550 Watts max when the lights and heater are on momentarily each day and only 150 24/7. Compared to a PC that's peanuts and doesn't require many J.
