What i do is take a shot glass, and add some reef roids or reef chili, and tank water. Let the stuff soak for a few min, then I add Fauna Marin LPS pellets to that "mixture" and let the pellets sit for like a min or so (just to get water logged). Then I just use a turkey baster and suck up a few pellets at a time and feed each LPS coral in my tank. Doing it this way means that each time you squirt some pellets on your LPS, they also get a bunch of the tiny food particles that are in the other foods mentioned that drop down on them as well, providing more of a "mixed" food source. In my opinion just seeing the feeding response alone from a scolymia should tell you that they def eat in the ocean, thus should be fed in our tanks.
As far as you question on NLS pellets, I do use those for fish but would recommend a coral specific pellet food. The fish pellets have some fillers in them, as well as more fish specific foods added where as the pellets are more so made out of plankton etc and thus would prolly be closer to a more "balanced" food for the corals. Again I personally would not use fish pellets long term, but I'm sure others have successfully. In the mean time if you don't have any coral pellets, frozen foods like mysis would work great for the scoly as well. I would place an order from some coral specific pellets though as they are just much easier to feed consistently (i.e. at least 2 times a week). Don't overfeed them, I typically give each soclymia in my tank anywhere from 5-10 pellets depending on how large the specific coral is.
