I might be wrong, but it is an algae not a phytoplankton.

Has anyone ever desolved organic spirulina plankton tablets and then
feed their corals ect...

I have been told by my LFS that the only kind of plankton to use is
when its frozen. why cant I just disolve plankton tablets and use
this, as the spirulina plankton tablets also are a very nutrient rich
food. I dont mind spending the $25.00 for the frozen Liquid life bio
plankton but I bet using desolved plankton tablets will work? At less
then .10 cent a tablet I'm sure they must provide the same results.
just a thought
