Nutrafin Cycle is a concentrated biological aquarium supplement containing beneficial bacteria that help establish and maintain a healthy biological filter in both new and established aquariums.
The beneficial bacteria go to work quickly to help break down toxic ammonia and nitrite, supporting stable water conditions and a healthier environment for fish and other aquatic inhabitants.
Cycle is especially useful when starting a new aquarium, adding new fish, performing water changes, or maintaining an established filtration system. Regular use helps maintain populations of beneficial bacteria and supports overall biological balance.
Nutrafin’s proprietary Bio-Floc technology helps preserve the stability, effectiveness, and shelf life of the beneficial bacterial cultures.
