    I am looking at getting a lighting hood as follows: 1.2m (for a 1.5 meter tank 820 deepwith numerous lps corals) which has two 250 watt metal halides and four 54 watt t5's. Can someone advise me on how to calculate the monthly electricity costs? Alternatively can i go t5's only? Say 8 39watt?

    Take the wattage, multiply with the number of hours it will run per day, multiply that by 31 days of a month. This is the total wattage in a month. Divide this by 1000 to get to kilowatt hours and then multiply with your electricity tariff. It wont be 100 percent accurate as you will have stepped tariffs but it will give you an idea.

    Also remember that the halides will take more than 250watts each as the ballast also uses some. In my case my magnetic ballasts take the same as the globe so i have a total wattage of 1000w on my 2 250w halides.
    As an example, i use 2 250w halides for 11 hours and 2 54w t5s for 12.5 hours. A guestimate for electricity is 440 per month.

    What would i need for a 1500l x 600w x 820h? in order to have a complete operating unit?

    What are the costs and is this also suspended above the tank?
