WATTAGE calculation
OK I don't really see the difference in power between these T5 tanks and a MH tank.
The first tank is 350g and tank dims (converted) are 6.5' long x 36 D x 24H. For lighting its using: 10 x ATI Aquablue special 80 Watt which equals 800 watts 4 x ATI Blue plus 80 Watt which equals 320 watts 6 x ATI Aquablue special 39 Watt which equals 234 watts 2 x ATI Blue plus 39 Watt which equals 78 watts Thats a grand total of 1432 watts over that tank. Second tank is 250g and tank dims are 6.5" L x 36 D x 28 H. 12 x 80 Watt ATI Powermodul which is a total of 960 watts. I think the main advantage the T5s have over MH is the even distribution of light throughout the tank.

Hey Chin,
On a 3' wide tank, you can't get really good coverage via MH ime. You'd have to put up two mh's back to back or use a light mover (light movers rule, btw). So in the first tank you listed out up there, to get adequate mh coverage without a light mover you'd need 6 mh lamps.. 6 x 400w = 2400w + actinics. Or you could probably get away with a couple of actinics and 2? mh's on a light mover, which imo would be pretty cool, although it would make the display look kinda funky (and would be tough for taking pics) but would probably be awesome for all around coral growth due to light coverage? Would be a fun experiment, too bad the wife won't let me have more then one tank. In any event, I think the original post was to validate the use of T5 lighting to grow SPS coral. I think T5's have been proven worthy of SPS so many times over it's a not a question of if you can run a successful SPS tank with them, but it's now become a just a matter of preference.

another thing to remember is a lot of these photos are staged for photo shoots and posted to hype a type of light. I find it strange that most of the "WOW" T5 photos are from europe, and that everyone has seen the pics but no one seams to have seen the tank in person.
Also if you look at that pic it is only an 87 pixel shot so itis very grainey to start so you can realy get a good look at the edges of the corals when you zoom in, and when viewing normaly you can just make out a "green" tint to things that shouldent be grren, like the shadows. these are some tricks that used to be used for "adding colour" or "oversaturation" I beleive a few of us posted pics a few years back that were doctered to hell, but we stated they were. If I would have reduced the pixels from 300 to 80 and reduced the size you would have never knowen. for all we know this tank coul dhave been set up just for the phot shoot, or could have been run with MH or what ever.
