DT’s Plankton Farm produces two unique products, specifically for feeding marine invertebrates kept in home aquariums and for research.
DT's Live Marine Phytoplankton
Live phytoplankton is an extremely important food for a great many animals that are maintained in reef aquariums. DT’s Live Marine Phytoplankton is concentrated and cleaned to provide nutritious live phytoplankton without the contamination of excessive nutrients or metals from the culture media. It is very rare for phytoplankton species to survive refrigerated storage. DT’s Plankton Farm only uses species that have been proven to survive refrigerated storage for the entire five month shelf life our “best if used by” date is based on. Marine reef aquariums can be populated with a variety of phytoplankton feeding animals. Although some of these animals may feed on preserved phytoplankton, some will reject dead phytoplankton or detritus as food and not consume it. Clams have been shown to reject nonliving partials, passing them instead as pseudo-feces.  Only live phytoplankton will be accepted by all phytoplankton feeding animals.
DT's Natural Reef Diet - Oyster Eggs
Oyster eggs are harvested and packaged as a food for corals. Oyster eggs are highly nutritious, with high levels of protein and omega3 fatty acids. The particle size is extremely small at approximately 45 microns. The combination of small size and soft texture makes this an easily captured food particle. Corals for which this food is particularly useful are those with poor prey capture responses and those with very small polyps.  Included are Porites, montipora, Goniopora, gorgonians, soft corals, and the oyster eggs even show some success with the maintenance of previously difficult or impossible to maintain azooxanthellate soft corals and seafans.

There is a research article concerning the nutritional quality of phytoplankton products in the aquarium trade. This was serious research that has been peer-reviewed and published in a research journal that has been made available by the researchers involved.
