phytoplankton culture

[nuch]

I bought this package from Florida aqua farms. I got 3 discs and that's to many. I also have a full 2lt. in the fridge, so I got plenty. If it's done right this one disc can be split many times. So I'm selling or trading 1 disc and enough f2 fertilizer to split many times. If need be I will tell how too. but it's pretty simple. $20 or trade. I will ship priority mail if need be.
