| Brucey cultureing your own is definately the way to go, its not only cheap its a better product. On the acro's or any sps they dont touch Phytoplankton (not on thier menu), really what you are doing is feeding particular critters, mosts clams/acros/lps dont touch phyto. You are however feeding larvae, some dusters and som sponges (although sponges go both ways. Phytoplanton is almost pure organic phosphate and can actually hurt the growth (calcification) of hard corals, so i would try to limit your feeding to what you know is going to use it and then skim like no other to remove the left over as well as you can, that way you can avoid a build up over time, On a side note lets see a pic of your tank, I dont think I have seen it yet.
