How much does it cost to run your tank?
 

I want to know how much it costs to run a tank because my mom thinks it's "expensive" to keep the lights on for longer than 4 hours.
For example, a light uses 30watts? How much does it cost per hr? A 300 watt heater + 30watt light for 10hrs a day + HOB= how much a month? I will find out my kilowatts price, but I don't know how to solve the above. If you could post how much it costs u to run a tank, it would really be helpful. I don't want to sound like a brat, I'm really greatful for even being able to run a tank, just a heads up. ;)
KWH price is 15 cents in California, is it the same as KW price?

Watts X how many hours in a day the lights are on x 365 / 1000 = x how much you pay per KWH =

Example 24 watts x 12 = 288 x 365= 105120 / 1000 = 105KW x .11 cents per KWH = $11.56 per year

I think i worked out once that just to run my 75 gallon, it costs around $650 a year. You also have to consider that fish tanks will produce heat... which will then contribute to your AC coming on for longer too !

*EDIT*
$650 for my 75 gallon & 30 gallon

it cost about $25-$35 a month for my 135 gallon during the winter. the main usage are the heaters i have. its cheaper in the summer since i dont even plug in my heaters.

My 30g costs $10 mth less in summer , with 2 canisters and 2x24w bulbs running 8hr a day ( thats at 23c pKw )

It's about $1/day for my 240 gallon.

I didn't know it was that expensive. O.O
My mom says the monthly electricity bill is 300$.

after much calculation and the assumption i'll refill my co2 tank monthly. my 75 gallon will cost me
$15.96 for electricity
and $39.24 for electricity + co2 + tax

water might cost me 1 dollar

Do what you can to bring the electricity bill down and then she might be more willing to let you have a tank. Turn the house lights off when you don't need them, open the blinds, use natural light. Don't use electricity when you don't have to. Unplug things you do not use. If she sees the bill going down, she will be more likely to let you run the tank.

AS a Mom of two sons- I completely agree with ABOVE ^^^^^^^^^

You gotta remember too that the heaters don't run 24/7. They only turn on when they're needed (when the temp drops below the set temp)

Switch to more efficient equipment if you have the money, LED lights for one.

why not use one of these to see exactly what you're using. then offer to pay for the power used

I read in a form that some public libraries have 1 of those kilo watt meters that you can check out and plug into anything you need in order to determine electricity usage

300 for a month is pretty expensive. Mine is about $100-120. Never turn on central ac/ heater.

i agree. ours is around 120-150. we've seen 188 depending on the time of year. we also have oil heat, so that helps with the electrical.

your tank should cos 12.97 per month..
this is assuming your 300 watt heater stays on 33% of the time which is 8 % higher than the standard accepted value of 25%
ur light assuming its efficiency is normal should use 33 watts
and your filter im assuming 27 watts at 24/h per day

heater - 8.56
light - 1.49
filter - 2.92
