Living nutrition
Nannochloropsis supplies proteins and beneficial fatty acids, including EPA. Its nutrition moves through the food web as organisms consume it.
100% LIVE NANNOCHLOROPSIS
Feed life to
your reef.
Living phytoplankton for corals, filter feeders, and the marine life that makes your reef thrive.
ALL NATURAL · NO PRESERVATIVES · NO ADDITIVES
LIVE NUTRITION. THRIVING REEF.
A living culture.A consistent feeding routine.A reef full of life.
SMALL CELLS. A BIG ROLE.
Nutrition starts at the
base of the food web.
Phytoplankton are microscopic algae. They turn light and nutrients into biomass that helps feed the smaller organisms in a marine ecosystem.
Feed the small mouths
Live phytoplankton can support suitable filter feeders and live-food cultures. Feeding response varies with species and the size of particles they can capture.
Support your reef routine
Use measured portions, observe your animals, and monitor water quality. Phytoplankton complements a varied feeding plan and regular reef care.

LABEL-BASED DOSING CALCULATOR
How much for your reef?
mL per dose
Starting label guidance: 5 mL per 10 gallons, 3–4 times per week.
Use actual water volume after rock and sand displacement. This calculation follows the label; adjust based on your reef’s response and water quality.

Grow phytoplankton
with a clean, consistent process.
A successful culture starts with healthy starter cells, clean equipment, suitable culture water, nutrients, light, and aeration.
01 Prepare a dedicated setup
Use a clean, transparent culture vessel with airline tubing, an air pump, a light, and a timer. Keep culture tools separate from aquarium equipment to reduce contamination.
02 Match your culture water and nutrients
Prepare clean saltwater and follow the starter supplier’s salinity guidance. Use a microalgae culture medium at its specified dose. Record your salinity and nutrient additions so each batch is repeatable.
03 Keep light and aeration consistent
Provide steady illumination on a timer and continuous gentle aeration to keep cells suspended. Avoid direct sun and overheating. Follow your culture supplier’s light and temperature guidance.
04 Watch the culture, not just the calendar
Record color, growth, temperature, and batch dates. A culture should grow progressively denser. Sudden clearing, unusual clumping, or an off odor may indicate a problem; isolate that batch and investigate before using it.
05 Harvest carefully and keep a backup
Use clean tools and retain a healthy starter for the next batch. A separate backup culture helps you recover if a batch fails. Follow a validated culture protocol for harvesting and storage.

GOOD TO KNOW
Before you feed.
Can phytoplankton replace other foods?
Keep a varied diet suited to your livestock. Not every coral or filter feeder consumes the same particles, and fish typically need additional foods.
How should I store my bottle?
Follow the bottle’s refrigeration instructions and use-by date. Our label specifies refrigeration after opening at 34–42 °F. Shake well before dosing.
