Quick Facts

  • Model: XY2835
  • Filter Type: Air-driven sponge filter
  • Recommended Tank Size: 40–150 Litres
  • Filtration: Mechanical + Biological
  • Power Source: Aquarium air pump (required)
  • Suitable For: Shrimp, fry, quarantine, community tanks

Is this for you?

✔️ Good if:

  • You keep shrimp or baby fish
  • You want gentle filtration
  • You run breeding or quarantine tanks
  • You value strong biological filtration

❌ Avoid if:

  • You want silent filter operation

Why this filter?

The XY2835 Sponge Filter is a proven aquarium filtration solution designed to provide stable biological filtration while maintaining a gentle water flow.

Dual sponge chambers create a large surface area for beneficial bacteria to colonise, helping break down ammonia and nitrite efficiently.

Its low-flow design makes it especially suitable for shrimp tanks, fry grow-out systems, hospital tanks, and sensitive fish species.

Key Features

  • Dual sponge biological filtration
  • Safe for shrimp and fry
  • Gentle water movement
  • Energy-efficient air-powered operation
  • Reliable design with no motor inside tank

Common mistakes

  • Cleaning sponge under tap water
  • Using undersized air pumps
  • Over-cleaning beneficial bacteria colonies
  • Expecting high mechanical polishing
  • Positioning too close to delicate plants

Use made simple

  • Connect airline tubing to air pump
  • Submerge filter fully in aquarium
  • Secure in a corner or rear section
  • Activate airflow via air pump
  • Allow beneficial bacteria to establish over time

Maintenance

  • Rinse sponge in removed tank water only
  • Clean gently during water changes
  • Do not sterilise or replace too frequently
  • Maintain steady airflow from air pump

Pair with

  • Aquarium air pump
  • Airline tubing and check valve
  • Shrimp breeding tanks
  • Hospital or quarantine setups
  • Supplemental biological filtration

Important Notes

  • Requires external air pump (sold separately)
  • Box packaging may vary depending on supplier
  • Ideal for gentle-flow aquariums
  • Best performance develops after cycling
  • Filter appearance may vary slightly by production batch
NTA Insight:
Sponge filters are often underestimated. For shrimp, fry, and breeding setups, they frequently outperform more expensive filters because they provide stability without dangerous intake suction.

FAQ

Do I need an air pump?

Yes. The filter must be powered by an external aquarium air pump.

Is it safe for shrimp and fry?

Yes. Sponge filters are among the safest options for small livestock.

How do I clean it?

Rinse gently in removed aquarium water during maintenance.

Can this be my only filter?

Yes, depending on tank size and stocking levels.

How long does it take to become biologically active?

Typically several weeks once beneficial bacteria establish.

    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.
