Key features

• •Efficient Multiple Filtration -- high density plant fiber mesh, can achieve better effect of bacterial culture. Moderate thickness, effective multiple filtration of residual food and suspended impurities. Nitrifying bacteria will effectively decompose impurities and purify the aquarium, making the water clearer and brighter.
• •Improve Water Quality -- strengthen filtration, such as fish feces in the tank, residual bait and suspended particle, prevent water from becoming muddy.
• •Nitrifying Bacteria Culture -- black biochemical cotton has good physical filtration and excellent biochemical filtration performance. It has the effect on decomposing excreta and feed residue, improving water quality, filtering and cleaning, and reducing fish mortality.
• •Washable -- clean the cotton about two month with fish tank water, do not use tap water, because biochemical cotton has a lot of parasitic nitrification bacteria inside.
• •o Deformation And Rub Resistance -- hollow polyester fiber, fine and soft, can be used repeatedly for cleaning, anti-extrusion and rubbing, not easy to damage or deformation, very suitable for the use of physical and biochemical filtration in the fish tank.
