Wild Phytoplankton as seen under a microscope.
Phytoplankton is a free-floating, microscopic plankton that exists naturally in the oceans, lakes, and rivers of the world. Phytoplankton, which are the bottom of the food chain, make up the primary food source for marine corals, claims, and filter feeding invertabrates
What does this mean to you?
In a closed system, such as a home aquarium, food sources are limited to what is added to the tank. Considering the needs of the various life kept in the system, a regular source of food must be added to mimic the constant availability of food in the ocean.
A must for any reef hobbiest!
