Nutrafin Cycle Biological Aquarium Supplement features a high-concentration formula that immediately establishes a safe biological aquarium environment. Cycle goes to work fast, releasing massive amounts of beneficial bacteria that eliminate toxic ammonia and nitrites and creates a biologically well-balanced aquarium for healthy fish to thrive. It is also ideal for quickly establishing safe and essential conditions in new aquarium setups, so that you can introduce fish to new aquariums immediately. Regular application of Nutrafin Cycle helps to competitively exclude the establishment of undesirable bacteria in aquariums. Nutrafin Cycle is an all-natural product that will not harm plants, animals or humans. It does not require refrigeration and it can be used in fresh and saltwater aquariums. Cycle provides consistent results thanks to the unique and proprietary bio-floc technology that preserves product stability, efficacy and shelf life. High-quality production processes ensure that every container of Cycle contains pure, safe bacterial colonies free of undesirable contaminants.
#### When to Use Nutrafin Cycle
1\. When starting any new aquarium. 2\. When adding new fish. 3\. When cleaning or replacing media inserts. 4\. After medicating. 5\. In case of fish loss. 6\. As a weekly supplement to maintain optimum water quality. **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 Information
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.
#### Product Benefits
