Phytoplankton starter culture - Calgary

[ivan]

Hi,
I want to start saline phytoplankton culture (green water) for feeding but I can't find starter culture here in Calgary. Any ideas where to find it?
I tried looking in local stores, but nobody seems to carry such risky item . Online prices were approachin $100 which seems little too much.
I do not need monoculture of specific strain, mix will do.

If you are in Calgary and have some green water in sea aquarium, please contact me at ivanivanca@yahoo.com

Thanks for your advices,

Ivan
