Feeding corals

[Madreefer]

How's bout just don't feed your corals anything but good ol fish poop? I've never fed my corals anything for years and they grow really good.
But I'm trying an expirement at the moment. I've started feeding Coral Frenzy since begining of Jan. I see no difference other than more pea soup in my skimmer cup and an ugly paly that's decided to spread quite fast. I'm doing this until June.
