Description:
After years of using 2 part nutrient options, we sourced the true F2 Gilliard's formula.
This globally preferred enrichment solution is used in the culture of marine phytoplankton.
Directions: Simply add 1 ml of F2 concentrate to 1 L of fresh saltwater at ~1.019 s.g., add your starter culture and light ~16 hours per day. 250ml is enough for approximately 250 liters at f/2 concentration.
Keep in a cool, dark area and shake prior to use. Use a clean syringe and secure cap correctly after use. Use within 6 months of opening.
