Choose media for your filter

  • Mechanical media: replacement foam sponges, polishing pads, Poly/Foam pads and intake pre-filter sponges.
  • Biological media: Seachem Matrix packs and Fluval AquaClear BIOMAX inserts, plus Bio-Foam options.
  • Chemical media: activated carbon, MatrixCarbon, zeolite, ammonia-remover inserts and selected combination media such as Zeo-Carb and Clear-Carb.
  • Replacement parts: a model-specific Fluval C4 impeller for maintenance or repairs.

Check model and media suitability

Match your filter's exact model, generation and replacement-part details before ordering. Tidal 35, 55, 75 and 110 products, Fluval C2, C3 and C4 media, and AquaClear sizes are not automatically interchangeable. Check dimensions, pack quantities and included components on each listing.

Mechanical, biological and chemical media serve different purposes. Check freshwater or marine suitability and the manufacturer's directions for each product, especially ammonia-removal and combination media. Follow treatment instructions when using carbon or other adsorptive media alongside aquarium medications.

This collection also includes complete Marina and Fluval hang-on filters, general-purpose Fluval carbon and OASE Hel-X pond biomedia. Check their intended application separately rather than assuming they are replacement parts for your hang-on filter. Additional delivery charges apply to the bulky OASE Hel-X 25-litre listing.
