F2
F2 is Oceansix’s phytoplankton fertilizer made 100% true to Guillard’s f/2 recipe. It delivers the classic balance of nitrate, phosphate, chelated trace metals and vitamins for clean, consistent phytoplankton growth in home and hatchery cultures alike.
Directions

Liquid: Dose 1 ml per 1 litre of phytoplankton culture. Shake well before use.
What’s Inside
