My Tank Thread
Do you have access to commercial products from Kent or Seachem? If so, I'd suggust looking at their vitamin/trace element products and use these to formulate Arman's F/2+ solution. You'll be famous! It might not be Guillard's exactly, but it would be close enough.
Also, were are you getting your phyto culture from? I would think they would have the supplies available for culturing.
