I feed Live Phyto, Cyclopeze, H20 Life frozen coral food, and Mysis. Every 4 days I target everything, and alternate between 2 different blends of food.
Feeding is really dependent on your stock and your lighting. I have a lot of LPS, a non- photosynthetic Sun coral, and a Copperband Butterfly. The Sun coral and Butterfly get Mysis daily. I feel feeding with varied foods helps promote healthy stock, as long as your system and maintenance schedule can handle the nutrients
