JBJ Hollow Ball helps to promote a strong colony of bacteria that eliminates NH, NF, NO, toxic heavy metal ions.

The bio media promotes a neutral water GH and pH, ensuring optimal aquarium water for the healthy development of fishes and plants.

Benefits

• Hollow design accelerates diffusion rate of nitrifying bacteria and enhances filtration efficiency
• Hollow cavity of filter media forms hypoxic environment, and accelerates growth and reproduction of anaerobic nitrifying bacteria
• Eliminates NH, NF, NO, noxious heavy metals, etc
• Maintains water at neutral GH and pH
• Provides a large surface area for bacteria adhesion
• Small individual dimension suitable for various filter sizes
• Lightweight
• Suitable for Fresh and Salt water
