Choose Tetra EX filter media by model and filtration stage
Tetra and compatible ZooBest filter media in this category are intended for specific Tetra EX and EX Plus external filters. The range includes biological foam, fine fleece, bio filter balls, ceramic rings, carbon media and model-specific replacement pads.
Identify the complete filter model and required filtration stage before ordering. Foam and fleece provide mechanical or combined filtration, ceramic rings and bio balls serve different structural or biological roles, and activated carbon is used for selected adsorbing applications. These media are not interchangeable merely because they fit the same filter family.
Clean or replace each medium according to its function and the filter instructions. Avoid replacing all biologically active media at the same time without a specific reason. Check pack size, model assignment and whether the product is an original Tetra or compatible replacement element.
