QUESTION:
We have been using the standard fertilization regime
for our microalgae cultures of Isochrysis and Chaetoceros in the oyster
hatchery. I would like to try using local fertilizer ingredients to mix up a
suitable replacement for the F/2 fertilizer that we have been purchasing. At
the moment, I'm less concerned with optimizing the media fertility levels as
I am with the cost of the fertilizer.
Does anyone have a simple recipe using local
ingredients such as 10-10-10, urea or Miracle-Gro for growing marine
microalgae?

COMMENTS 1:
We have successfully been using a product called
AquasolTM (HorticoTM Pty Ltd, Australia) to grow these algal species. It is
a soluble fertiliser with a N:P:K ratio of 23:4:18. Also need to add sodium
meta-silicate and iron chelate for diatoms
