Reusable fine-mesh filtration media bag designed for secure media containment in aquarium filters

Quick Facts

  • Size: 32 × 14 cm (12.5” × 5.5”)
  • Mesh: Fine 16 mesh construction
  • Closure: Corrosion-resistant zipper
  • Capacity: Approx. 1 litre of media
  • Suitable For: Freshwater & marine aquariums
  • Reusable: Yes

Is this for you?

✔️ Good if:

  • You use loose filtration media
  • You want a reusable media holder
  • You run canister, sump, or internal filtration
  • You use finer media like Purigen or resins

❌ Avoid if:

  • You need an ultra-large media bag

  • You want disposable filter bags

Why this media bag?

The Seachem Zip Bag provides a secure and reusable way to contain filtration media while allowing efficient water flow through your filter system.

Its corrosion-resistant zipper replaces traditional drawstring bags, reducing the risk of media escaping into your filtration chamber.

The fine 16 mesh construction is especially useful for smaller filtration products like Purigen, resins, carbon, and biological media.

Common mistakes

  • Overfilling the bag → reduces water flow
  • Not rinsing media before installation
  • Using oversized bags in compact filters
  • Forgetting to clean the bag during maintenance
  • Using incorrect mesh size for extremely fine powders

Use made simple

  • Fill with chosen filtration media
  • Zip securely closed
  • Place inside filter chamber or sump
  • Allow water to pass through media naturally
  • Remove, rinse, and reuse during maintenance

Pair with

  • Seachem Purigen
  • Seachem Matrix
  • Activated carbon
  • Resin-based media
  • Canister or sump filtration systems
NTA Insight:
Medium-sized zip bags are often the most practical size for hobbyists — large enough for effective media volume but compact enough to fit most canister and internal filters.

    Live Arrival & Ordering FAQ

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
