lighing for 240 gallon

[castor]

It's a 240 gallon but I am going to only be using half of it for zoas. I was thinking two 2 bulb t5. Two fixtures so I could space them. Would that be plenty of light for them?

not really. Over a 240 i would run atleast 3 250 watt halides.

This is only going over half the tank, 4 feet, so think 120g
