Live Phytoplankton saltwater culture / HELP

[ScienceTeen]

I have a science experiment underway and have tried unsuccessfully this week to grow live phytoplankton ("Phyto Feast" from Reef Nutrition) in saltwater without success.
I don't have another week to try again, and would like to find an already-cultured sample this weekend (November 4-6) to keep going with experiment.
Please call (604) 220-5032 if you can point me in the right direction to purchase, or best, for free.
