Oyster Feast is by far the best coral food on the market for SPS. I also use Roti Feast. I alternate feeding days with each of these products. 1 TSP OysterFeast one day, 3 TSPs RotiFeast the next. Hard to beat Reef Nutrition stuff. I've never seen such good PE with any other food and my groeth and color lately has been great. Of course, its not readily available in the LFS by me in Orlando, FL. I order it from Aquarium Specialty online.
On the weekends, before my weekly water change, I spot feed all corals with Cyclopeeze and Coral Vibrance for SPS and Mysis and Rods for LPS.
