Have you tested calcium, alkalinity, and magnesium? How about nitrate an phosphate? Do you keep your tank at a proper reef specific gravity of 1.026 or 35 ppt? If these are all within proper range, and you have fish in there that you feed, then your corals are likely quite happy between the fish poop, excess fish food (hopefully not much), and the elements in the salt mix.
If you insist on trying
something, then I suggest you try target feeding some of the LPS with an LPS pellet like Fauna Marin LPS Pellets (my fav). Keep in mind that feeding the corals is the same as feeding the fish as far as nutrient load goes, so watch for algae.
I don't recommend feeding into the water column unless you have a really good protein skimmer, a really good clean up crew, and a good amount of experience in the hobby to see the signs of impending algae bloom
before it happens.
EDIT: I just realized these 3 threads are all from you.
Skip the questions in the first paragraph, I saw the answers in your other thread and made comments in your other threads regarding those values.
