I have the following thing sucking in power

2 X Aquaclear 50
1 X 200W Hagen heater
1 X Pump (it's rated @ 80Gallon)
1 X florecentlight (T12, 4')

everything is 24/7 the light is probably 8 to 10 hours a day, i wanna chart up and see how much it cost per month is there anyways to do this?

Contact your power company they should be able to tell you how to calculate power useage.

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

Welcome to FP warlock110.
Do as Keith suggested & you'll get the best answer possible.

You should be ble to calculate the usage based on watts for each electrical appliance with the exception of the heater as it cycles on and off dependent on the difference in your desired tank temperature and the ambient temperature of your residence.

Each unit has a watt "draw" and each unit runs 24/7 with the exception of your lighting and the aforementioned heater. Add the watts for the

Each unit has a watt "draw" and each unit runs 24/7 with the exception of your lighting and the aforementioned heater. Add the watts for the Aquaclear plus the second Aquaclear (AC) and the pump. This provides you with the base wattage per hour. If each AC draws 30 watts and your pump draws 40 watts. You then consume 100 watts or 0.1 kilowatts in one hour (kWh). To that number add the draw of your fixture.

as bob said add wattages together to come up with a total. at work i go on full load when doing calculations as this gives max cost . so say you had a 100w light, 100w filter and 300w heater= 500w. now power companies charge out kilowatt hours {1000w for 1 hour}. so in the example your using 12Kw hours a day so if its 10cents a Kw/h =$1.20 a day. so now all you have to do is work out how many Kw/h you use and how much you get charged to get an idea. i shudder to think how much my tanks cost each bill.

OH TOLEEDY!

I'd done a calculation on my 20 gallon tank a few winters back, just in case my sister ever complained about me using a larger portion of the electric bill (never mind it is my house ). At the time it had an AC 150, 1 30 watt bulb, and a 100 watt heater set on the lowest temp. By my estimates it used less than 20 watts an hour over a 24 hour period. Since I wasn't using my alarmclock anyway I simply unplugged that as compensation :%). Additionally I do keep my tanks insulated in winter, and fish that can handle a wider range of temperatures (68-90ish) so that I have more control over the temp of the tank and therefore the ammount of electricity wasted.
