More info

Each Bio-Sphere has up to 54sqm surface area (580sqft). Such ultra-high surface area means extremely large bacterial colonies can be established, resulting in more efficient bio filtration for your aquarium. Hence, the Nano-Tech Bio-Sphere quickly improves the quality and stability of the water column.

It is developed from stabilized microbial sewage treatment technology (W-BAF) and is highly effective in removing Ammonia-Nitrogen (NH4-N) and Nitrate-Nitrogen (NO3-N) from water.

Bio-Sphere supports the growth of different species of bacteria and fungi, such as nitrifying bacteria (including species of the genera Nitrosomonas, Nitrosococcus, Nitrobacter and Nitrococcus), yeast, phototrophic prokaryotes, etc.
