This is entirely dependant on the size of the reef tank and the equipment you choose to run it. I would estimate however that the average reef aquarium of between 40 and 90 US gallons uses somewhere in the neighborhood of 500-600 watts during the day(more due to lights), and about ~300 watts at night.
The larger the tank, the easier it is to maintain. So if you are new to this, stay with the 55 gallon, research a lot, and be patient with saltwater aquariums.
in kw we use
With the price of electricity high and expected to get much higher I do not use much electricity and waste even less
They use about 1200 watts of electricity, which is a LOT!
A lot of electricity a day
non ur business
14 electricity bolts per hour.
Trains don't use electricity it uses coal trams use however electricity.
In which area?
You cannot use the "word" coral reef in a sentence, but you can use the "words" coral and reef adjacent to each other in a sentence.
Depends on the size of said tank. Or if you are talking about a military tank then it depends on which tank you are talking about.
None. Light bulbs use electricity, they do not create electricity.
