Sera bio fibers effectively collect coarse dirt particles for biomechanical filtration. Thus, you can protect subsequent filtration media from coarse contamination and increase the biological efficiency of the filter. Suitable for freshwater, marine, and pond water filtration.

Sera bio fibers also serve as an excellent medium for breeding and a hiding place for juveniles. Moreover, they are perfectly suitable for transporting shrimp, providing a base for the animals in transport bags and thus ensuring they are subjected to less stress.
