I use oyster feast I just add it by my mp 40 so it gets blown around for my lps I'll hand feed mysis once In a while
have to watch trying to feed corals, that you dont get a nutrient build up, other then spot feeding you are taking this chance, i do not feed my corals at all other then what they might catch from what i feed fish and fish poop
If you want to feed some LPS frags, what I do is I set up a 2.5 gallon with a heater and a frag rack in it and I just take a gallon from my main tank and put all the corals I want to spot feed on the frag rack and feed them mysis. Very easy to do.
