Hi Gianluca,
Sorry, I've been out of sync with this reef forum. I'm looking for a new car and have been involving in more activity in my car forums.
My tank dimension is rough 30"x20". The fixture is about 8" from the water line. I feel the coverage is quite good. With 28"x28", I think you should be able to cover it. I'm using 100% blue, 100% pure blue, and 60% white. You'll have to hang the fixture higher and bump up the intensity. I worryabout the 28" width of your tank. Since the fixture is only about 6" wide, it might present a problem. Not sure....
Lighting the tank is one thing but are LEDs THE light for reef tank? I believe the light intensity, not I'm not sure on the light spectrum.
I'm not sure if it's my tank chemistry(which I think I got under control and rock stable) or it's the light but my SPS are not going that great. Some SPS are growing, some are not. For the ones that grow, it's mostly green corals. For the ones that don't grow, the color turns to green. I feel like this LED fixture is turning my SPS to green slowly regardless of the original color of the SPS! My plan is to keep the LED lit without messing with the intensity for another 2 months and see if the colors of the SPS indeed change to green or not. If it does, I'm hanging my Elos planet II(250W DE w/ 4 24W T5) back on the tank. I just want to see this LED technology to succeed in a reef so I'm giving it more time. But so far, I'm not very impress with the color.
Interestingly though, all my clams and LPS are doing great!
I'll have some update this weekend with full tank pics and some of my growth and colors.
