  • Marine Aquarists have found Phytoplankton to be beneficial in maintaining Corals, Sponges, Clams, Scallops,Tubeworms, Sea Squirts and almost all filter feeding animals.

  • They have also found that Phytoplankton helps to balance their systems PH by removing excess Carbon Dioxide and adding Oxygen.

  • As well as a water conditioner and food, Phytoplankton has been found to supply less understood benefits.

  • Theraputic, almost antibiotic- like effects have been reported on fish and other marine animals.

  • This may be a clue to compounds expelled by the algae itself rather than by the removal of nutrients and chemicals from the water.

  • Phytoplankton will feed and help to increase the biomass of Zooplankton within a marine system, such as Ciliates, Copepods, Rotifers, and some marine Shrimps which are considered essential for the survival of some fishes and inverts.
