Monthly Electric Cost For Your Tank

[braselton4]

All,

Over the past 3 months I have noticed a dramatic increase in my in my electric usage. Unfortunately, the GA Pwr website will not let me go back any further than a year so I do not know my usage history since I put in my tank in June/July of last year. The increase is pretty significant, averaged over the last 3 months, I have used around 1200 kwh's more each month than the same periods last year. Here is a list of what I am running:

2 65w PC bulbs
2 96w PC bulbs
2 Hydor powerheads
1 Iwaki mag40
1 9.5b submersible pump
1 1200 maxijet pump in my RO tank
2 300 watt heaters

I recently added a 20k Metal Halide but that was only 2 weeks ago.

I just want to know if this is normal usage for a tank or is my tank not to blame? Thanks in advance.

Take the wattage of whatever you have, multiply by the number of hours its running per day, divide by 1000 and you have how many kilowatt hours your take uses each day.

Multiply that by 30(days a month), then multiply that by your current rate from the power company.

MATH!

My 480 system and 150g QT system runs me around $200 a month on average.

Considering my power bill is around $100 with 3 tanks running I dont worry about my power bill...

 

[jello!]

Our power bill is 61$ with a 10gal, 12gal, 37cube, and two 55's running. There hasnt been any significant difference. It used to be 50$ something before starting up all the tanks.

You could go to one of the big box stores and buy a "P3 Kill-A-Watt" device which you can then put inline with you equipment to get a real-time cost monitor. It's basically an automatic calculator for figuring power consumption cost. I got one and have used it on lots of stuff (computers, lights, etc...) to better understand my power bill.

most likely the heat is what's killing you over the last 3 months.

7 return pumps
6 skimmers
1 filter(mandarin/pipefish)
44 t-5 bulbs

I wish I could have had them all plummed together! I had no idea the hobby would have become an obsession!!:lol2:

+1. HD usually has the for about $30.

I used it around the house to figure out how much other stuff was sucking out of me while it was "off".

My tank costs me around $30 a month for everything.

Here is the math. A day has 24 hours. On average a month has 30 days. Therefore there are 720 hours in a month. 1 kwh is 1000 watts running for 1 hour. So 1200 kwh is 1,200,000 wh. Divide that by 720 and you get 1666 watts running per hour. 1666 watts divided by 120 volts equals 13.88 amps. While a good size set up could draw that it would be from the time you set it up. It could not have increased that much all at once three months ago.
