For feeding SPS (and really all corals), the 'pappone' method is best. Fresh oyster, clam, shrimp, mussel, chopped up/blended and fed in small quantities once or twice per week. At lights out, put in an amino acid supplement to tell corals to extend their polyps (that's really what the added aminos do, I haven't seen any data that suggests they are able to uptake amino acids from the water column before they are broken down), and one hour later, add the pappone, 5mL of it per 20 gallons or so. Turn your skimmer off during that night, or else all that food will be skimmed up long before the corals can take advantage of it.
All the protein in those foods can be broken down into dozens of amino acids, notably some which corals need. I've seen tanks fed with pappone (Italian tanks, that's where it started) that have immense coral growth in a much shorter time frame than in tanks not being fed (up to 34cm per year growth for most Acropora).
