Couple of Questions on Growing Phytoplankton

[AUFishGuy]

My LFS sells DT's Phytoplankton, can i start a culture with this product? Where besides aqua-farms can i buy Micro Algae Grow? Or is there another fertilizer product you suggest

I don't know but being in a fridge would make it not the best culture starter. It looks like it is actually 3 types of Phytoplantkton and most cultures are usually only one pure strain. Biological supply houses carry many different types of pure cultures along with the products you need to have to grow them.
