Maxspect Nano-Tech Bio-Spheres are a new filter media for use in freshwater and marine water aquariums.


With an ultra-high surface cross-cutting ratio and filtration area for the establishment of bacterial colonies. With the use of stabilized microbial sewage treatment technology (W-BAF), the Bio-Spheres have a unique advantage in the treatment of water column with high
Ammonia-Nitrogen (NH4-N) and high Nitrate-Nitrogen (NO3-N).


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


Only 10 pieces Nano-Tech Bio-Sphere can replace up to 20lbs (10kgs) live rocks.


Putting all Nano-Tech Bio-Sphere in mesh bag make it easy to maintenance and save huge place for other equipments. It can be used in both fresh water and seawater environment.

•  stabilized microbial sewage treatment technology with Biological Aerated Filter (W-BAF)
•  ultra-high surface cross-cutting ratio and filtration area
•  Nano-Tech Bio-Sphere is made of ceramic beads and is completely inert
•  individual use in filter sump, external filter, internal filter
•  can also simply be placed into the aquarium
•  suitable for fresh and marine water aquariums
•  content: 1kg of Bio-Sphere

The Bio-Spheres should be cleaned or replaced every 6 months for optimal results, however when cleaning/replacing old Bio-Spheres, DO NOT replace all of them at the same time. Clean/replace half of the Bio-Spheres such that there are sufficient bacterial colonies remain to reestablish themselves in the newly cleaned/replaced Bio-Spheres.
