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.
With the price of electricity high and expected to get much higher I do not use much electricity and waste even less
in kw we use
They use about 1200 watts of electricity, which is a LOT!
non ur business
A lot of electricity a day
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.
