If the with is 36" i would go with the large lumenarcs 19"x19" withe the single end bulbs minimum 250's, if you can go with the 400" would be great if your tank is going to be mostly sps. you would get a larger area coverage with this reflector in my opinion and yes if you go 10k you would need vho or t5s suppliments.if the tank's 36" wide, you swtill have At least 16 t0 17" room for suppliment reflectors. the ice cap t5's take about 3" inches from each side. hope this helps
thanks everyone, I was looking to avoid the whole DIY thing...but looks like I will have to 'bite it'...the fixture I was considering was the sfiligoi infinity, but magnetic ballasts that aren't US made are a concern
