Ceramic base, combined with a special component made from a group of minerals that release negative ions.
Negative ions help neutralize water and maintain the pH level between 7.0-7.2.
They stimulate the growth of nitrifying bacteria colonies and improve water clarity.

Bio-Spheres are characterized by establishing bacterial colonies in the form of composite bio-nanofilms, allowing different types of bacteria and fungi to grow on their extensive surface, such as nitrifying bacteria (including species from the genera Nitrosomonas, Nitrosococcus, Nitrobacter, and Nitrococcus), yeast, phototrophic archaea, and others.

• Specifically designed for freshwater aquariums only (not suitable for marine tanks);
• Widely used in freshwater aquariums in China and Southeast Asia for over a decade;
• Each type provides different benefits and features for various types of freshwater aquariums;
• Bio-nanotechnology spheres are made from non-reactive ceramic material, with additional components to provide different properties;
• All bio-nanotechnology spheres have been kiln-fired for over 6 hours, resulting in strong and stable bio-media that last for years.
