The secret to explosive Daphnia and Moina cultures is greenwater — dense with live phytoplankton that provides continuous, nutritious food around the clock. Hydralife's concentrated phytoplankton starter cultures create greenwater quickly and reliably for any scale of live feed production. Order at hydralife.org.

Powdered algae supplements are convenient — but live phytoplankton is biologically superior. Active cells provide enzymes, intact fatty acids, and biochemical signals that dried products cannot replicate. For Daphnia, Moina, brine shrimp, and copepods, live beats dry every time. Order at hydralife.org.

Live feeding carries risk only when organisms are wild-caught or poorly cultured. Moina and Daphnia raised on Hydralife's clean, concentrated live phytoplankton grow in controlled conditions — free of pathogens and pollutants — delivering all the benefits of live feeding with complete peace of mind.
