I found feeding corals just polluted the water (tried the Papone thing). My 7" Regal Tang provides plenty of food for my corals anyway. As for color, I noticed a big improvement when I stared dosing Iodine.

what size food should SPS be getting?

i thought reefroids was good for them :(

maybe it was one of the other foods i bought that had smaller sized food particles.

cyclop-eeze or whatever it's called works well, size wise.

fauna marine ultralith is all i add to my tank now. My po4 and nitrate levels are almost to zero now. my water is as clear as air now. and my corals color are taking off. i love this system. about 30 bucks a month i bet on my 120 sps tank.
