Nano-Tech Bio-Media is made of ceramic beads and is completely inert. Stabilized microbial sewage treatment technology with Biological Aerated Filter (W-BAF). Ultra-high surface cross-cutting ratio and filtration area. With an ultra-high surface cross-cutting ratio and filtration area, each Bio-Sphere has up to 54m² surface area (580ft²) and each Bio-Block has up to 1,080m² surface area (11,635ft²) for the establishment of bacterial colonies, which allows it to effectively control the quality and stability of the water column.With the use of stabilized microbial sewage treatment technology (W-BAF), the Bio-Media 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/Bio-Blocks 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 bacteria (including species of the genera Nitrosomonas, Nitrosococcus, Nitrobacter and Nitrococcus), yeast, phototrophic prokaryotes, etc.The Bio-Spheres/Bio-Blocks are carefully manufactured to ensure its quality, the well-designed porous structure of the Bio-Spheres/Bio-Blocks create the ideal living conditions and environment for bacterial colonies, but will not be decomposed by the bacterial colonies that grows within it.DirectionsJust 10 pieces of Nano-Tech Bio-Sphere can replace up to 20lbs (10kgs) live rocks.For Bio-Blocks, simply place them directly in your sump or area with high water flow.Putting all Nano-Tech Bio-Sphere in mesh bag make maintenance easier, and save a huge amount of space for other equipment. It can be used in both fresh water and seawater environment.The Bio-Spheres/Bio-Blocks should be cleaned or replaced every 6 months for optimal results, however when cleaning/replacing old Bio-Spheres/Bio-Blocks, DO NOT replace all of them at the same time. Clean/replace half of the Bio-Spheres/Bio-Blocks such that there are sufficient bacterial colonies remain to re-establish themselves in the newly cleaned/replaced Bio-Spheres/Bio-Blocks.
