Live Phytoplankton

Nannochlorpsis oculata* (not acquired from CSIRO Microalgae supply service). Great for feeding live rotifers or dosing an aquarium to feed zooplankton (such as harpacticoid copepods). It can also form part of an aquarium's biofiltration as phytoplankton utilizes nitrogen and phosphate in its growth phase. This culture is grown using media specifically formulated for phytoplankton, not terrestrial plant fertilizers, which can result in unwanted excess nutrients or heavy metals.

* This strain is believed to be Nannochlorpsis oculata. However, as it is not kept under stringent axenic conditions, purity can not be guaranteed.

Suggested Dosage Instructions:

To feed rotifer culture: feed until rotifer culture is lightly tinted (ideally twice daily or as necessary).

To feed aquarium: 5ml per 50 litres daily


If kept refrigerated, it will last for up to a month from harvest date (noted on the underside).



250ml culture of Harpacticoid copepods (adult size less than 1mm). Ideal for boosting copepod population or for directly feeding fish like Mandarins and Coral gobies.
