What else is there to know about Cycle?
Fish keeping, like life, is all about balance. Fish will only thrive when their water is in perfect harmony, with enough good bacteria available to neutralize harmful ammonia and nitrite. Nutrafin Cycle works to keep balance your aquarium water so your fish have the ideal environment to live in.
Technical InformationNutrafin Cycle significantly increases the speed at which robust beneficial bacteria populate the aquarium and is also able to immediately metabolize greater quantities of ammonia and nitrite. The Cycle formulation has been supercharged and adapts and responds to demanding conditions. 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.
Lab testing has clearly demonstrated Cycle to be able to metabolize up to 40mg per liter of ammonia in approximately 24 hours. Nutrafin Cycle features a robust group of bacteria that are highly adaptive and responsive.
