Heres an option no-one has mentioned, T-5 lighting is what I use and with the sunlight supply kits with their parabolic reflectiors they allow you to keep everything! Low power comsumption, almost non existant heat issues, and you replace the bulbs every year and a half! For your tank you could get a 4 54 watt retrokit with icecap ballasts (ice cap because they overdrive the bulbs and actually some how increase life to two years) and that would give you, with overdrive 320 watts, perfect for everything! I'm going to attach a pic of rjwilson's tank to show you how it works. I use the 3 foot bulbs on my 58 wich is the same as your 75, just a foot shorter
