I want to use it to breed more copepods, last time I measure my salinity after adding in the salt it was at like 1.30+
Are you culturing in 2 liter bottles?
Poor choice for copepods.
nannochloropsis is generally a poor choice for copepods. I could be wrong, but Isocrysis would probably be a better phyto to use. Each phyto has different concentrations of protein, fats, DHAs, etc. Phyto is not the best choice to use, but probably the easiest to culture.
