I currently have 2-175HQIs and 2-110VHOs on my 100gal SPS Reef (48x24x20H). I am looking for either a retro kit to go into my existing canopy, or get a fixuture and get rid of the canopy all together. However, I like the canopy because it keeps unwanted light from shinning into the room in the mornings/evenings. Almost all of my corals are within 10" of the waters surface (most have grown all the way to the surface). I was thinking 6 bulbs with individual reflectors, but I am wondering it 8 will be needed. Anyone have any input on how many I should run? Also, if you recommend a fixture, which one?
