I think you need to look at something else besides lack of food for your corals not thriving. What you're suggesting looks more like a recipe too keep your LFS guys well fed
I haven't found that any of my corals, except my sun coral, need to be fed to thrive. Feeding just speeds up their growth.
When I get my new tank stable, I'm going to start feeding "Pappone" a couple of times a week.
