Imo, SPS do not need to be fed unless you're achieving ULNS (ultra low nutrient system) via carbon dosing whether that be biopellets, Zeovit, vodka, Fauna Marin, Prodibio, vinegar, etc. If you have achieved ULNS your tank will have no algae, extremely low phosphate and nitrate, and your SPS will be pale/pastel colored. Otherwise, I don't think there is much benefit to feeding SPS corals, and find that feeding attempts tend to spark algae blooms more than anything. The corals should get enough nutrients from photosynthesis and miniscule bits of fish food in the water column.
