Sera Biofibres Coarse 40g[Weight - 40g]

sera biofibres are perfect for biomechanical prefiltration, efficiently trapping larger dirt particles. This way, you can safeguard the subsequent filter media from heavy contamination and enhance the biological performance of your filter. They are compatible with freshwater, saltwater, and pond water filtration systems.

Additionally, sera biofibres serve as a fantastic spawning medium and provide a safe hiding spot for fry. They are also ideal for transporting shrimps – the fibres offer a stable grip for the creatures in transport bags, reducing their stress levels during transit.
