is there a easy formula to work out power consumption per wattage.
trying to work out how much itll cost to run my heat/lights/filters etc over a period of time.
i need to know before i go an buy heaps of setups, i dont want to get my power bill and get any nasty shocks..
i cant work it out, admittedly my brain cell count is a li'l on the low side,
when i first got my li'l360 my power bill doubled, i dont use it as much now, although "gears of war" is about to be released so i might be in trouble
