its been a long time since i had to think about this,
but i am under the impression that corals (in general) eat zooplanktons, not phytoplankton. meat not plants. When you feed your tank phytoplanktons what your actually doing if feeding the infauna in the live rocks and sand bed, and its their nauplii that are feeding the corals.
Now some non-photosynthetic corals requires phytos (dendronepthias come to mind), and others like suncorals require larger zooplanktons.
actually many corals do better if they are fed, as it supplements their nutrition they receive from photosynthesis
feeding the tank w/ phytos and rotifers is a good thing, but you might not be directly feeding the corals w/ what you think.
Interesting...I just buy coral food and never understood the details.
