Shop aquarium canister filters at The Tech Den Australia, from compact external filters for smaller tanks to larger models for high-volume aquariums. Explore Fluval, Eheim, Aqua One, Oase, Aquael, Bioscape, Sicce, Aquatopia and Ultum Nature Systems.

Compare external aquarium filters

  • Browse ranges including Fluval 07 and FX, Eheim Classic and Professional, Aqua One Nautilus and Ocellaris, and Ultum Nature Systems Delta.
  • Explore selected UV-equipped models and filter-and-heater combinations, including Oase BioMaster Thermo, Bioscape PRO and Aquatopia Thermotech Plus.

Choose a canister filter for your tank

Compare the recommended aquarium volume, flow rate, media capacity and freshwater or marine suitability on each product page. Check the filter dimensions, hose connections, included media and fittings before ordering. Features such as UV, heating and electronic controls vary by model.

Follow the manufacturer's setup and maintenance instructions rather than a fixed cleaning interval. Check individual listings for special-order lead times and delivery conditions; additional charges apply to some bulky or heavy filters.
