A tank of this length and depth would reguire no more than HO T5's in my opinion. My tank has a 33 footprint and all I have is normal output tubes-yes a whopping 90watts=3 per gallon. By the time you add sand and rockwork, one should have more than enough areas to keep softies, LPS, and yes even SPS

I agree. MH should be used for punching through the water of deeper tanks, but T-5's are adequate to keep SPS in shallower ones.
Aqualine (makers of the Aquaspacelight) has now come out with an all T-5 light fixture. I think Wai's has them in stock now here in Calgary.
