Liquid Life Phytoplankton for reef aquariums. MUST BE SHIPPED OVERNIGHT Frozen product. 32 ml bottle with pump dispenser. Contains three different strains of live Phytoplankton. One of the most important needs of a captive reef habitat is to have the nutrient needs of its biological process meet. Though captive reef tanks can live without feeding phytoplankton, inhabitants survive but do not thrive. Meeting the minimum needs produces a minimum return. Yet in captive environments, aquarists use filtration methods that remove and often strip water of vital organic and inorganic elements causing captive reef environments to be less than ideal. Using planktonic feeds allows you to put back Mother Nature's Liquid Life by transferring essential fatty acids and vitamins from algae to captive inhabitants. Zooplankton, Clams, Hard and Soft Corals, and Filter feeding Invertebrates can all uptake BioPlankton either by Direct or Indirect Feeding. BioPlankton will help organisms to have higher growth rates, survivability, and presentation. Coral reefs accommodate a diverse and complex community. Population density and diversity are affected by availability and acceptability of food. To meet these demands, BioPlankton starts at the bottom of the food chain. The three different algae contained in BioPlankton provide a variety of feed particle sizes and nutritional profiles that meets each organism's feeding need. Direct feeding is accomplished by an organism directly ingesting a passing Phytoplankton cell in its natural state. For example, a filter feeding sponge, tunicate, feather duster, clam, bivalve, or coral that captures and feeds on Phytoplankton. Idirect Feeding is the product of a Zooplankton organism uptaking the Phytoplankton, and enriching itself before being consumed by another animal itself. Now with the enrichment of a reef's Zooplankton that is present in the substrate and rock.
