Metal halides

Hey guys I just got offered a 400watt metal halide set up for free for my 55 bow front I'm just wondering how I can set it up like the height from the water and if I should run fans to cool it down this is the set up

Is that 2 x 400 watts? That's going to heat up the tank and the room. That's also a lot of light. Are you doing an sps tank?

it all depends on what your running now and height that it is, also keep in mind that free light will cost you $150 a year in new bulbs and higher energy cost thru out the year. Try and find out how old the bulbs are as they may need changed out be4 it goes into service

They don't make 200 watt halides, so they are either 150, 250, or 400 a piece. You can change the color with different lamps, but you cannot change the wattage by changing the lamps.
I would recommend Phoenix 14k, XM 20k, or Radium 20k. That will give you a nice, bluish look.

Excess heating of the water will be your biggest challenge without a chiller, especially in the summer time.

If I run a few fans on the tank to cool blow some of the heat around it would help at all the tanks I'm my bed room for now but may be getting shut down for a bit due to me having a babe and no room in the house

Babes first, fish tanks second?
That way dramatically increases evaporation, but can help.

I have two 400 watt metal halides on my 300 gallon tank. Ran them 8 hrs per day. They raised the tank temperature 4-6 degrees even being over a foot above the tank with a fan running and open top. I would be wary about putting them over a 55 gallon tank.
