Please don't follow a watt per gallon rule when looking at lighting your tank.
I would also say to go with T-5's for your tank. A lot less headach then MH. While halides are nice and they will give the water a shimmer affect the T-5's will last longer and wont heat up the water as much. They will also cost you less each month.
Yes my vote would be the T-5's all the way.............
MH lighting is nice for reflections and shadowing due to their point source properties. The shimmer is nice...BUT...The heat , continual need for bulb replacement and power cost over time are making them the second choice for many these days.....
With the quality of reflector fitted T-5' out there today the MH just does not match up anymore..(I have the Nova Extreme Pro on my 72 and can keep just about anything)... It has a low initial cost, and has all you need in the box. Two decent fans, a decent electronic ballast, legs and bulb shield all included..I did change some color combination with the first bulb replacements last year....The original bulbs provide a very bright "white light" appearance.This is the same 48 inch wide size light as you will need.
Times are changing. If you had ask this question 5 years back MH would have been my choice, but not today......
Someone also mentioned PC lighting........ I like Dinosaurs too but this is the 21st century. they are the next thing to obsolete. They should already be "extinct" ..........Also the old "watts per gallon" statements are somewhat misleading in figuring out what one needs....... PAR light reflective values are better at determining depth penetration, which is far more important than total wattage........
Maybe the old "watts per gallon" ideas and PC lights can share the same grave ..........
Remember that your lighting is probably the single most important investment in having a quality Reef Tank...... Good Luck....Warren
