Phaeodactylum tricornutum is a marine diatom widely used in aquaculture and live-feed culture. It provides EPA and natural pigments, including fucoxanthin, which can help broaden the nutritional profile offered to copepods, rotifers, filter feeders, and other small marine organisms.

This species is a good choice for customers who want more variety than a single green phytoplankton strain. It can be fed directly to an aquarium or used to enrich live food cultures before they are fed to fish and corals. Its naturally golden-brown color is normal for this species.

Phaeodactylum is unusual among diatoms because it can grow without added silicate under many culture conditions. Customers culturing it at home should still use clean saltwater, proper fertilizer, steady aeration, and daylight-spectrum lighting.

Grown, harvested, and bottled in Texas. Refrigerate after delivery and shake gently before each use.
