You'll only need 3 MHs over your tank if you have mediocre reflectors like the little ones you get with the Outer Orbit. Two Lumenmax reflectors over my 72" tank covers the entire length just fine.
Really?! I bought 2 lumenmax's (mogul base) and I needed to add a third in the middle otherwise it was too dark. How high above the tank do you have them? I'd love to see a pic if you got one.
