I have a 30" deep tank, with the halides at 6" above the water surface I can grow SPS on the sand, they actually do better down there. If I were to raise the lighting about 12" I should be able to grow SPS effectively down to about 15" below the water surface or right about where the tops of my lower piles of rock work sits, which gives me the bottom half of the rock work for lower light coral.
Thoughts? I guess it doesn't hurt to try it out.
