Cloudy Aquarium Water Has a Better Path to Clear
Support clearer freshwater aquarium water — nitrifying bacteria for biological filtration, no mixing or measuring, placed on filter cotton rather than directly in the tank.
Why Are These Aquarium Tablets Perfect for You?
✔ Supports beneficial bacteria: Each tablet contains nitrifying bacteria designed to support beneficial bacterial colonies in the aquarium filtration system. These bacteria contribute to biological filtration and help maintain a more stable freshwater aquarium environment.
✔ Complements existing filtration: Designed to work alongside an existing aquarium filter, the tablets support biological filtration as part of regular maintenance. They are intended for ordinary cloudy or turbid water conditions, not green or yellow water.
✔ Simple tablet application: No mixing or measuring is required. Place a tablet directly on clean, permeable filter cotton—not in the aquarium water—and keep the oxygen pump running during use.
