Do you want to create the natural food chain for your saltwater aquarium system? Aqua Medic has created a series of breeders including the Aquabreed 1000, the Plankton Light Reactor and the Plankton Reactor to help cultivate artemia cysts, phytoplankton and zooplankton, respectfully. The artemia cysts feed the phytoplankton which feeds the zooplankton which is used to feed your fish larvae and many invertebrates in your saltwater aquarium.
