This is a common and widely used general enriched seawater medium designed for growing coastal marine algae. The concentration of the original formulation, termed "f Medium" (Guillard and Ryther 1962), has been reduced by half.
This media is disinfected using UV radiation.
The default is WITHOUT silica. Please comment if you would like it with silica (for diatoms and other silica requiring organisms).
Great for dinoflagellates, especially bioluminescent Pyrocystis fusiformis!
