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.
Nutrafin 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.
