I have a 2L Tetraselmis phytoplankton culture that doubles every four days. At present it goes into a 5G bucket of Apocalypse Copepods. In addittion to air bubbler this zooplankton culture is illuminated for 16hrs with 40W led grow light. It was my intention to continue growing phytoplankton as Copepods were consuming phyto. Also in 5G bucket is Red Grapes & Feather Caulerpa. When pod density in 5G bucket is self sustaining, I will add pods to a diy pod generator.
