Lighting suggestions?

[gqlmao]

Hello, Im going to build a canopy for my tank, its been topless for a couple months now, I need suggestions!. I'm currently running 4 t-5s right now. SPS frags seem to do okay. My tank is a cube its 30x30x24 which is pretty deep. When im done my canopy I'm thinking of adding either an mh 400 or 250 watt or another 4 bulbs of t-5s which one do you guys prefer? the t-5s are 24 inch by the way.

Since I have two bigger angels I'm just keeping sps and other hard species of corals. What would be best in the long run? I know that I'm going to need excessive fan cooling in the summer with MH as my tank gets hot now. But I do adore that shimmer .

Based on experience, cost, and expertise what do canreefers have to say?
