New 75G light setup

[Jason7181]

I am setting up a 75G reef tank and was wondering what lighting system I should go with. I want to keep some SPS and a clam or 2. Can anyone suggest a light setup? I wanted to maybe go with a DIY LED setup but I don't know which way to go MH or LED.

Metal Halides gets my vote. 2 150w halides and some T5 actinics would do a wonderful job on that size tank.....I am working on a 75g with 40 breeder sump myself.

Would I have to get a chiller if I have a canopy?
