Once hatched, I would have them in a growout bottle and fed them greenwater made from spirulina powder from BrineShrimpDirect.com.
From that, I would remove enough for a day and then enrich for two 12 hour stages with new water and new enrichment for each stage. (bacteria reasons)
Nauplii are gut loaded after 12 hours, but after the second 12 hour period they have already assimilated the nutrients into their flesh, making them much better as a food.
So, while I enrich daily, I only enrich each day what I need for the next.
