Sera Biofibres Coarse 40g - Filter Material for Mechanical Pre-filtering

Sera Biofibres Grosse are filter fibres for the biomechanical pre-filtration of coarse dirt particles. They protect subsequent filter media from coarse dirt, increasing the biological effectiveness of the filter. Suitable for fresh, marine and pond water.

💡 Expert tip: Place the Biofibres Grosse as the first stage in the filter, before sponges and biological media: they intercept larger debris and drastically reduce the frequency of cleaning for other materials. When cleaning them, always rinse them with tank water to avoid eliminating the nitrifying bacteria that colonize them over time. Their use as a support for transporting shrimp is an often underestimated bonus: it concretely reduces losses during transport.
