How would you light up a sps dominant system?

I hear ya on the MH.

I still remember rocking the single ended 400s with huge reflectors. only took 2 to light my 180 and you could put sps everywhere! add 2 VHOs and Boom youre done!

if it weren't for the size of fixture/canopy/hood needed for it, i'd consider them for sure. if only I was doing an in-wall with a fishroom.

having said that, the DE MH fixtures I've used just didn't cut it on spread. i'm sure if you raise lights high enough the spread would be better, but I don't think I've ever had a fixture more than 8" above the tank.

You'd need more than 2 DE for sure. Jamie ran 2 x DE on his 120 with pretty good results!
