LCA NP Free – Nitrate & Phosphate Free Aquarium Fertiliser

Feed freshwater aquarium plants with potassium and essential trace elements without adding extra nitrate or phosphate.

Quick Facts

  • Brand: Liverpool Creek Aquariums (LCA)
  • Type: Liquid aquarium plant fertiliser without added nitrate or phosphate
  • Supplies: Potassium and micronutrients; manufacturer also describes a carbon-based component
  • Best suited to: Planted freshwater aquariums with existing nitrate and phosphate availability, including higher-bioload setups
  • Sizes: 250ml and 500ml pump bottles; 1000ml refill without pump

Is this for you?

✔️ Perfect if:

  • Your fish feeding, stocking or substrate already supplies enough nitrate and phosphate.
  • You want to supplement potassium and trace nutrients without adding more N or P.
  • You are starting a planted aquarium with nutrient-rich aquasoil and want a controlled dosing approach.

❌ Avoid if:

  • Your plants are nitrogen- or phosphorus-deficient and need those nutrients supplemented.
  • You expect this to remove existing nitrate or phosphate from the water; it does not.
  • You need to avoid carbon-based liquid additives in a sensitive livestock setup without checking compatibility.

Why choose LCA NP Free?

Unlike a conventional NPK fertiliser, LCA NP Free adds potassium and a blend of micronutrients without supplying additional nitrate or phosphate. LCA positions it for aquariums with high biological loads or nutrient-rich substrates, where nitrogen and phosphorus may already be abundant. This makes it a useful targeted choice when the aquarium does not need further N or P.

Benefits

  • Supplies potassium and trace elements for healthy plant development.
  • Does not add nitrate or phosphate.
  • Provides a flexible option for higher-bioload planted tanks.
  • Manufacturer describes a carbon-based component to support its intended plant-care routine.
  • Available in pump bottles or a larger refill.

Dosing made simple

  • Shake the bottle and follow the current manufacturer's instructions on the product label.
  • LCA describes a three-times-weekly routine where nitrate and phosphate are already adequate, but the actual volume per dose must be taken from the bottle label.
  • Start conservatively and adjust to aquarium volume, plant growth, water parameters and livestock response.
  • Check nitrate and phosphate levels periodically: this product does not replenish either nutrient.
  • Do not exceed the manufacturer's directions. Use extra care with sensitive aquatic animals and carbon-based additives.

Pairs perfectly with

  • Appropriate aquarium nitrate and phosphate test kits.
  • Consistent aquarium lighting and regular water changes.
  • Nutrient-rich planted substrates and healthy aquatic plants.
NTA Insight: “NP Free” means no added nitrate or phosphate—not that it removes them. For a heavily stocked planted tank, check what your fish waste and feeding already contribute before deciding whether to use this instead of a full NPK fertiliser. A low-nitrate tank may still need a separate nitrogen source.

FAQ

Does NP Free lower nitrate and phosphate?

No. It is formulated without those nutrients; it is not a nitrate or phosphate remover.

Can I use NP Free in a new aquasoil tank?

LCA recommends NP Free during the early period of nutrient-rich substrates. Begin with conservative dosing and monitor plant growth and water chemistry.

Is it suitable for shrimp?

LCA describes the trace-element mix as suitable for shrimp tanks. However, consider the carbon-based component and the sensitivity of your particular shrimp species before use.

Can this replace NPK fertiliser?

Only when the aquarium already has enough nitrate and phosphate. If those nutrients are deficient, an appropriate NPK or targeted supplement may be necessary.

Does the 1000ml refill include a pump?

No. The manufacturer's 1000ml refill is supplied without a pump dispenser.

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    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.
