    so i'm thinking about grabbing a metal halide from someone on craigslist for an awesome price. Not including the LED's, it has an output of about 720 watts. that's about 9 watts per gallon for my 75g tank. is this to much?

    i dont want to hang the light from the ceiling so it's only going to be on the stands.

    Thats fine. I actually have more than that. Just be sure to acclimate your corals.

    or! what if i were to replace the 250w halides with 150w ones? would the ballasts cause them to have a shorter life span?

    You could pull it off if you slowly acclimate the corals to the light intensity but IME why would you WANT to use so much wattage... Energy bill is gonna spike and most of your corals will photosaturate at PAR levels lower than what you will be providing...
