My own bias is to caution against coral feeding. Its difficult enough to control the nutrient cycle in our little glass boxes without adding organic matter. Fish food, fish poop, nutrients from the subsrtate and bacteria etc., should provide all the nutrients your corals need without risking nutrient build up, nitrates, algae blooms etc. And keep in mind, many or even most corals rely primarily on embedde photosynthetic algae which rely on light energy to produce nutrients for the host corals. Marketers will have you believe that you can't live without their products. I don't feed anything but the fish and corals grow like weeds. Having said that, there are a few corals that do require nutrients directly from the water colum since they have no photosynthetic capability (e.g., dendronepthia, scleronethia, sun polyps etc) however I typically recommend against owning these for that reason.
