Phosphate-removing filter media for freshwater and marine aquariums

Quick Facts

  • Product Type: Phosphate remover
  • Size: 50g bagged
  • Brand: Seachem
  • Use: Phosphate and silicate control
  • Water Type: Freshwater and marine

Is this for you?

✔️ Good if:

  • You are managing phosphate levels
  • You have algae driven by excess nutrients
  • You run freshwater or marine filtration
  • You want targeted chemical filtration

❌ Avoid if:

  • You have not tested phosphate
  • You expect it to replace maintenance
  • You need biological filtration only
  • You want a plant fertiliser product

Why this product?

Seachem PhosNet is a granular ferric oxide media designed to remove phosphate and silicate from aquarium water.

Phosphate control can help reduce algae pressure when combined with good feeding, water changes, and lighting management.

It should be used as part of a broader maintenance strategy rather than as a magic algae cure.

Common mistakes

  • Using without testing phosphate
  • Overusing chemical media unnecessarily
  • Ignoring root causes of algae
  • Placing media where water flow is poor
  • Not replacing exhausted media

Use made simple

  • Place in a fine media bag
  • Rinse before use if required
  • Position in strong filter flow
  • Monitor phosphate levels
  • Replace when exhausted

Pair with

  • Seachem media bags
  • Canister or sump filtration
  • Phosphate test kits
  • Algae management routines
  • Activated carbon or Purigen where appropriate

Important Notes

  • Test phosphate where possible
  • Use in adequate water flow
  • Do not rely on media alone for algae control
  • Follow manufacturer directions
NTA Insight:
Phosphate removers help, but they do not solve bad habits. Overfeeding and poor maintenance will beat any media eventually.

    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.
