I feed quite a bit, and it works wonders. 130 gallon display, but I use the same ratio for my propagation tanks whether they have sps or not because feeding helps everything.
Daily: Reef nutrition phytoplankton, roughly 1 drop per gallon. Oyster feast, rotifers, or nauplii rotating throughout the week. Also dose acropower.
For LPS I feed a mixture of small high protein pellets, medium pellets, mysis, and krill if the polyps are big enough.
My philosophy is this, corals have their entire body dedicated to catching food, and feed voraciously on the reef, why on earth shouldn't we feed them in our reef systems. Sure, it adds some issues with nutrient control but we can always control it, so we should.
