I have a 90 gal corner tank with roughly the same dimensions as yours. I have one MH 10K across the middle towards the back and 2x36" T5 across the front (1xfiji purple and 1x10K). The single MH in the back covers that smaller area pretty well and the 2-T5s are enough for the front area. I have SPS growing well throughout the tank. Photo period: T5: 9:00am to 9:00 pm and MH: noon to 8:00 pm. Moonlights on .5 hours before and after.
See the video I took 3 months ago below. Just after that was taken I changed the T5 bulbs as they were getting old. They were a 14Kand a super actinic. The tank is quite a bit brighter with the new bulbs.
