Hey

Do i need 3 MH over 72" or can i get away with just 2.

I would go with 3 at least. They say 1 halide for every 2 feet.

You`ll need to go with three or the top braces will cast shadows in your tank.

IMO the only way you could consider getting away with it would be to use some really good reflectors like the Sunlight Supply Lumen Max reflectors, they cover a ridicolous area.

I agree they cover a big area but there will always be the top braces on your tank that will cast shadows on some areas of your tank. You wont be able to escape them unless you have all three areas covered.

A local guy here has always ran 2 400's on his 125. Not sure about the shadow issue though. I never noticed one though. I think 3 would be the best route.
