F2 Phytoplankton Fertilizer – 20g (Guillard’s f/2 Formula)

Achieve clean, consistent, and nutrient-balanced phytoplankton growth with OceanSix F2 Phytoplankton Fertilizer — a premium nutrient blend made 100% true to Guillard’s original f/2 recipe. Perfect for both home and professional hatchery cultures, this formula provides the precise ratio of nitrate, phosphate, trace metals, and vitamins required for strong, healthy phytoplankton development.

True to Guillard’s Proven Formula

Developed to match the time-tested Guillard’s f/2 medium, OceanSix F2 ensures your phytoplankton cultures receive the ideal nutrient balance for growth, reproduction, and cell stability. This tried-and-tested nutrient mix has long been the standard in marine hatcheries, research laboratories, and reef hobbyist setups around the world. With OceanSix F2, you can enjoy that same laboratory-grade consistency in your home cultures.

Complete Nutrition for Phytoplankton Growth

F2 provides a comprehensive mix of macronutrients and micronutrients that phytoplankton need to thrive:

• Nitrate and phosphate salts deliver essential nitrogen and phosphorus for cellular structure and energy.

• Chelated trace metals — including iron (Fe), manganese (Mn), zinc (Zn), cobalt (Co), copper (Cu), and molybdenum (Mo) — support vital metabolic processes and pigment formation.

• Essential vitamins B1 (thiamine), B7 (biotin), and B12 (cyanocobalamin) promote enzyme activity, DNA synthesis, and healthy cell division.

The result is a nutrient-rich growth medium that produces dense, vibrant, and clean phytoplankton cultures ideal for feeding copepods, rotifers, corals, and filter-feeding invertebrates.

Easy to Mix and Use

OceanSix F2 is available in both powder and liquid forms for your convenience:

Powder (20g):

• Mix 20 g of powder in 100 ml of RO/DI water to create a concentrated stock solution.

• Dose 1 ml of this concentrate per 1 litre of phytoplankton culture for standard f/2 strength.

• Shake before each use to ensure even nutrient distribution.

Liquid (Pre-mixed 125 ml):

• Dose 1 ml per 1 litre of phytoplankton culture directly.

• Shake well before every use.

This simple dosing method makes OceanSix F2 suitable for both manual culture setups and automated dosing systems, allowing you to maintain stable, consistent nutrient levels without guesswork.

Clean and Consistent Results

Because OceanSix follows the exact Guillard’s f/2 formulation, you can rely on predictable performance with every batch. Your phytoplankton will grow cleanly — free from unwanted contaminants or excess nutrients — and maintain optimal nutritional value for your reef ecosystem.

Safe and Reliable Ingredients

OceanSix F2 uses high-purity laboratory-grade chemicals to ensure accuracy, solubility, and consistency. The chelated metals remain bioavailable to phytoplankton while preventing unwanted precipitation in the culture vessel. This results in a stable, clear culture that’s easy to harvest and feed to your marine livestock.

Storage Instructions

• Store the powder sealed in a cool, dry place.

• Refrigerate any liquid F2 or powder-made stock solution after opening.

• For best performance, use within 6 months of mixing or opening.

Proper storage ensures your F2 maintains its full potency and guarantees reliable nutrient delivery to your phytoplankton cultures over time.
