here's what i add twice a week - i know, most of it is too large for my sps, but i have lots of lps and zoas, not to mention clams. i add this stuff into the clam tank so they get first shot at it.

three capfulls (15mL)coral stimulator from CB pets

one capfull of each of these:
phytoplex, zooplex, microvert, and chromaplex

4 drops of ZoeCon (this shuts down my skimmer for a few hours, so the liquid food isnt pulled out immediately)

keep in mind, i have about a 400 gallon system, so it isnt as much as it seems.

on the days i add this stuff - some of my sps have 1/2" long polyps - im not kidding.
