Feed Your Reef From the Bottom Up

Give your reef a powerful boost of live, nutrient-rich phytoplankton with our Green Phytoplankton (Tetraselmis chui) and Gold Phytoplankton (Tisochrysis lutea).

These two premium live microalgae work together to help nourish corals, copepods, clams, sponges, feather dusters, filter feeders, rotifers, and other beneficial microfauna throughout your aquarium.

Instead of feeding just your corals, phytoplankton helps feed the entire reef ecosystem.

Why Reef Keepers Use Live Phytoplankton

Regular phytoplankton feeding can help:

• Increase copepod and microfauna populations

• Support stronger coral polyp extension

• Provide natural nutrition for filter feeders

• Feed clams, sponges, feather dusters, and NPS corals

• Support vibrant coral coloration and overall health

• Encourage greater biodiversity throughout your reef

• Provide an additional natural food source for your aquarium

Better Together

Why choose only one?

Green and Gold Phytoplankton offer different nutritional profiles, making them an excellent combination for reef keepers who want to provide their aquarium with a more diverse and complete live-food source.

Rotate between the two or use them together to provide your reef with a broader range of nutrients and help support everything from microscopic copepods to prized corals and clams.

Build a Healthier, More Active Reef

A thriving reef starts with the smallest organisms in the system.

Adding live phytoplankton helps support the microscopic food web that your corals, pods, and filter feeders depend on — creating a more active, diverse, and naturally fed aquarium.

Feed the reef. Feed the pods. Feed the ecosystem.

Feeding & Storage

Shake well before every use.

Dose into a high-flow area of the aquarium for maximum distribution or target feed animals that benefit from concentrated feeding.

Refrigerate after opening.

For best quality, use within approximately 4–6 weeks and follow the storage instructions on the bottle.
