I only feed my fish once a day... twice when they look hungry hehe.. but mostly only once.
Your corals will get the vast majority they need from excess stuff in the water and photosynthesis. I rarely feed any of my corals, and when I do I spot feed them. I have monitipora SPS, birdsnest SPS, zoos, torch, frogspawn, a plate coral (which I do occasionally feed a silverside just to watch him eat), a nice green tooth coral, galaxia, leather, and a few others I cant remember the name of. I've seen great growth, especially with the sps's with only feeding occasionally... just making sure everything has adequate flow and lighting.
I'm with the rest... if you are dosing B-Ionic you should be fine. Just read on the back of that bottle and see what all is in that stuff haha.
