Check the exact filter model, media type and required size. Distinguish BF biological foam, FF fine fleece and the Brillant replacement sponge before ordering.
Choose Tetra replacement media for the exact filter
Tetra replacement filter media in this category serve different filters and filtration tasks. BF biological foam and FF fine filter fleece are intended for compatible Tetra EX external filters, while the Brillant replacement sponge belongs to the corresponding Tetra Brillant filter.
Identify the complete filter model before ordering and select the correct size or variant. Biological foam provides colonisation area for filter bacteria, whereas fine fleece retains smaller particles. These media are not interchangeable simply because they are used in the same filter series.
Clean or replace each medium according to its function and the manufacturer's maintenance instructions. Do not replace all biologically active material at once without a specific reason, and ensure that the filter is returned to operation promptly after servicing.
