Chris/Paul: Yes, that was the order. There is also a Chlorella (or something like that) that DT's puts in their blended phyto. It might be something worth looking into.
Adam/Chris/Paul: I'm definitely game at sharing the cost of those cultures. I refuse to attempt to raise any fish larvae until I have at least Tahitian Isochrysis and Nannochloris or Nannochloropsis. Thanks to Adam, I have Nannochloris already. I don't need Tetraselmis to complete my task, but I like the immune system boost that they give growing larvae.
