Nutrafin Cycle Biological Aquarium Supplement immediately establishes a safe biological aquarium environment for your fish. The Nutrafin Cycle Biological Aquarium Supplement features a new high concentration formula that reduces fish loss and establishes essential conditions in new aquarium set-ups. Potentially toxic ammonia and nitrite are rendered harmless to your aquarium inhabitants.
Cycle is composed of 5 strains of nitrifying bacteria. In addition to this, heterotrophic bacteria are also included to complement the actions of the included nitrifyers by converting organic waste to inorganic (ammonia & nitrite) compounds for conversion to nitrate.
