Tell us more about this interesting tank! I hope you can access it from all 4
sides, otherwise it's time to buy a diving mask and aspirin for the backaches.
Following Victor Eng, suppose that a 400w MH does illuminate only 24"x24".
Maybe that's enough. Do you really need intense lighting at the edges? (if you
answer no, won't you have less algae to scrape?)
I saw a square tank once that had MH in the middle and purplish Gro-Lux-type
bulbs along the outer edges. The cardinal tetras looked great!
