Zoas and Zooplankton

[ZoWhat]

I've been brewing nanno phyto for well over a year and doing really well with it

QUESTION - What kind of zooplankton would be beneficial for additional health of zoas using the nanno phyto I already grow?

I cannot specifically answer this question (I have no coral experience). However (and hopefully I am following your line of thought), corals do not feed on phytoplankton (plants) which is different from the zooplankton (animals) which many of them can eat.
Or maybe your are referring to culturing zooplankton (like copepods) with phytoplankton?
