⚗️ What It Does

Phytoplankton are the foundation of aquatic food webs — feeding copepods, rotifers, corals, clams, and filter feeders. For these microorganisms to thrive, they need precise ratios of nitrogen, phosphorus, trace metals, and vitamins. Oceansix F2 Liquid reproduces this balance with laboratory accuracy, ensuring dense, green, and nutrient-rich cultures without excess nutrients or instability.

Each millilitre contains the optimal balance of:

• Nitrate and Phosphate Salts – Core macronutrients for photosynthesis and cell division.

• Chelated Trace Metals – Iron (Fe), Manganese (Mn), Zinc (Zn), Cobalt (Co), Copper (Cu), and Molybdenum (Mo) to support enzyme activity and pigment formation.

• Essential Vitamins – B1 (Thiamine), B7 (Biotin), and B12 (Cyanocobalamin) for healthy metabolic and reproductive processes.

Together, these components create an environment where phytoplankton grow rapidly and remain nutritionally complete for feeding reef and aquaculture species.

💧 How to Use

1. Shake well before every use to evenly disperse nutrients.

2. Dose 1 ml per 1 litre of phytoplankton culture medium.

3. Aerate and illuminate your culture vessel as usual for optimal growth.

4. Once harvested, restart with freshly sterilized seawater and repeat dosing for continuous production.

💡 Tip: If you notice culture slowdown or light coloration, check your salinity and temperature before increasing dosage slightly.
