want to create your own phytoplankton? ... i found a great site and have followed these directions for a good bit of time now with great results...only thing I did differently was bought my starter culture locally. this is the first step in the food chain...my personal plans this time is to raise ALL live food i can.. phytoplankton,rotifers,copepods,brine shrimp,and mysis. Only on a level to feed my tank, and if I have more culture than I can use, maybe it will make its way here.
