Shop aquarium filter media at The Tech Den Australia. Compare biological media, filter wool, sponge pads, activated carbon and specialist resins for canister filters, internal filters, hang-on filters and sumps. The range also includes selected pond media, replacement cartridges, media bags and holders.
Match media to your freshwater, marine, reef, planted aquarium or pond setup. Mechanical media collects particles, biological media provides surfaces for bacterial colonisation, and chemical media targets particular substances. These roles are not interchangeable, and clear water alone does not confirm suitable water chemistry.
For replacement pads and cartridges, check the exact filter model, part code, dimensions and pack quantity. For loose media, compare basket space, particle size, placement and flow requirements. Specialist media may need a particular setup or application rather than simply being added to any filter.
Choose mesh fine enough to retain your media while allowing water to pass through. Small resins such as Purigen and Macropore need a suitably rated resin bag; a coarse bag is not an equivalent substitute. Avoid packing bags so tightly that they restrict flow.
Follow the product and filter instructions for preparation, cleaning, replacement and regeneration. Not every resin or carbon blend can be regenerated in the same way. Check compatibility with medications, plant nutrients and livestock where applicable, and use relevant water tests when selecting targeted chemical media.
Check individual listings for retail or OEM packaging, included media, special orders and pickup restrictions. Selected bulk media carries additional delivery costs; some large sheets and rolls are listed for in-store pickup.
