Ceramic base, combined with special ingredient made with a combination of tourmaline, maifanitum, actinolite and volcanic rocks minerals
Minerals that releases far infrared (FIR) with wavelength between 4-12 m, helps with water clarity and removes foul odor
A weak 0.06mA circuit released by tourmaline, helps breaking down chlorine in tap water used for water change

The Bio-Spheres excel at establishing bacterial colonies in forms of Bio-Nano Composite Films, it allows different species of bacteria and fungi to grow on its large surface area, such as nitrifying acteria (including species of the genera Nitrosomonas, Nitrosococcus, Nitrobacter and Nitrococcus), yeast, phototrophic prokaryotes, etc.

• Designed specifically for freshwater aquariums only (not suitable for marine aquariums);
• Widely used in freshwater aquariums in China and SE Asia for over a decade;
• Each variant provides different benefits and features for different types of freshwater aquariums;
• Nano-Tech Bio-Spheres are made with inert ceramic material, with added ingredients to provide different characteristics;
• All Nano-Tech Bio-Spheres are fired in oven for over 6 hours, resulting in a very strong and stable bio media that last for years.
