    Default Do you know how much it costs/month to run your tank?

    today my fish tank was pinned on the high electricity bill so that made me wonder how much my tank was actually costing to run/month. the total came out to about $36 to run my 120. so if any of you ever wondered how to figure out the costs of your tank just do these few easy steps.

    1. Total up the watts per day for the item to get total watts/day.
    2. Divide total watts/day by 1000 to get the total kilowatt hours (Kwh) per day.
    3. Multiply the Kwh/day times the cost per Kwh to get your total cost/day.
    4. To find out the average total cost per month, multiply the total cost/day by 30. (Power company monthly billing cycles vary from 28-33 days)

    here is the equipment I run 24-7
    heater = 100w
    AI modules = 75w*2
    Ocean runner 3000 return pump = 65w
    Sedra 2500 skimmer pump = 25w
    Mp40 powerhead = 28w

    the total comes out at 368watts
    so now you want to calculate the amount you consume per day simple multiply by 24 hours
    368w*24 hours =8832w/day

    now you take the watts per day and divide by 1000 to get the kilowatt hours which for me should come out to
    8.8kwh.

    then just multiply the kilowatt hours by your power companys rate, ours is $0.14/kwh
    which should come out to about $1.20 to run/day for my tank
    then multiply by 30 to get the total about monthly which came out to $36.95/month.

    of course it wont be exact because some things like the lights and heaters dont actually run full capacity 24-7 but its a good estimate of how much your tank actually costs to run monthly hope this helps, im actually a little curious to see how much its costs some of our members with multiple tanks or very large tanks!

    I don't even want to know...but I figure about $100 a mth. Since setting up the cube and the 60g, it's about 100 more a month on my bill.....so I'm just assuming.

    Frys Electronics has Kill A Watt meters on sale all the time for $15. Plug the tank in to one of those and you can get an exact amount of energy it uses and if you have the upgraded Kill A Watt it even calculates costs and other usage patterns.
    I bought one 5 years ago when I added a chiller and 3 years ago sold the chiller in favor of fans.
    I also found my lighting was the main culprit so converted to LED 3 months ago and cut my tanks electric usage by $50 a month. It does not take long to pay for LED with savings like that especially when I sold my MH/VHO retro for $200 to help with the cost of the new lights.

    Sorry not shot down...just trying to help.

    Good topic though. I researched my current equipment on my 29 biocube and came up with the numbers below... ~$8/month.

    energy costs - Do you know how much it costs/month to run your tank?

    electrical costs2 - Do you know how much it costs/month to run your tank?
