So seeing as this thread talks about the immovable opinions of high horse riders, I'll modify my previous statements on the board.

Ok, you don't NEED MH, you can run a successful SPS tank, or any other tank, with T5s. I wouldn't, and it's not about color or growth. I've never used them other than for actinic supplementation, but for me, the value in MH is the point source lighting. This gives my tank a sparkle that is not possible with T5, at least not to a degree I'm happy with. I've been to real reefs, and want mine to look real, and for me, only MH can give me that. If you're happy with a flatter (less contrasty ?) look, then T5 will probably work just fine. I also don't need to tune my color, I want the color to look like a reef at noon, and mine does with 14k AC bulbs. I've never been to Fiji, so I'm not sure if Fiji really is purple, but boasting a lighting system based on Fiji purple or Tonga Tourquiose, to me, is not keeping a natural look. Again, not everyone is looking for the "look" I am, so use whatever you want.
Growth? Who cares? The coral is going to grow under any sufficiently bright light, and really, I've always tried to slow my growth, makes for more room on the picnic table.
As for coral color, there are so many factors beyond lighting, that most people ignore, it's not even worth discussing in a lighting thread. I don't care what kind of light you use, if these other items are not addressed, you're going to have brown coral. If these items are addressed, you're going to have colorful corals, regardless of whether you use T5 or MH. Sure, there appear to be some pigmentation differences between the two types, again falling to personal preference.

So sure, you don't NEED MH, but I do. It gives me what I want in a tank, regardless of any other concern (power, heat, cost, etc). The end point in this hobby is me coming home to look at my tank, with the look I want, and for me, this can only be done with MH. I need MH.

(oh, and Greg, you need MH too)
