# 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?

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 __________________ “We didn’t underestimate them.

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. __________________ DBP Club #18

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. __________________

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

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.
