Feeding corals?

[msmith619]

I have been doing a lot of reading, here, reef central, google-ing etc and get a lot of different, sometimes conflicting info on coral feeding.
I keep soft corals, zoas, and LPS corals. Currently I have 4 different Zoas, 3 different green star polyps, 2 different brain corals, several kenya trees, a toadstool leather, and a pipe organ coral. They all look great and no losses.
Some articles say they don't need to be fed, photosynthesis is all they need- bright lighting (T5 or metal halides). Some say phyto-plankton, some say zoo-plankton and yet others say if you feed your fish, the excess as well as the fish waste feed the corals. My kenya trees and green star polyps are growng but everything else is staying the same size. I have had no new pylyps in the 6 weeks I have had the Zoas.
I run T5 actinics 12 hours and the T5 whites 10 hours a day and feed a lot of frozen food (3 times daily) and there is a lot of milky discharge from the frozen food and I only target feed my green BTA half to 1/3 of a silverside. The BTA moves if it is not fed 1 or 2 times a week. With feedings it is happy, swells and looks great.
What do you feed?
Also, does the time of day make a difference? i.e evening before the lights go off, etc.
