Description

LCA Iron (DTPA) Aquarium Plant Fertiliser

Give your freshwater aquatic plants a targeted source of iron to support healthy growth and rich green foliage.

Quick Facts

  • Brand: Liverpool Creek Aquariums (LCA)
  • Type: DTPA-chelated liquid iron supplement
  • Suitable for: Freshwater planted aquariums
  • Available sizes: 250ml and 500ml
  • Application: Pump dispenser; 1 pump = 2ml according to the supplier's dosing guide
  • Purpose: Supplements iron as part of a balanced aquatic plant fertilising routine

Is this for you?

✔️ Perfect if:

  • Your planted tank needs additional iron as part of its fertiliser routine.
  • You want an easy-to-measure liquid supplement for a freshwater aquascape.
  • You already manage lighting, plant nutrition and regular water changes.

❌ Avoid if:

  • You need a complete all-in-one fertiliser: this product supplies iron, not every essential plant nutrient.
  • You are hoping iron alone will solve every yellowing or poorly growing plant; symptoms can have several causes.

Why choose LCA Iron (DTPA)?

Iron plays an important role in chlorophyll formation and normal plant development. DTPA chelation helps keep iron available in aquarium water. The pump bottle makes routine dosing straightforward, whether you run a simple planted tank or a more demanding aquascape.

Benefits

  • Targeted iron supplementation for freshwater aquatic plants.
  • Supports chlorophyll production and healthy new growth when iron is limiting.
  • Convenient liquid dosing with a pump dispenser.
  • Two bottle sizes to suit different aquarium routines.

Dosing made simple

  • Shake well before use.
  • Standard planted aquarium: 1 pump (2ml) per 100L, three times weekly, with a 50% weekly water change, following the supplier's guidance.
  • Low-light aquarium: The supplier suggests the standard dose once or twice weekly.
  • High-light, CO2-injected aquarium: Supplier guidance allows up to 3 pumps (6ml) per 100L per dose, three times weekly, when appropriate for plant demand.
  • Maximum: Do not exceed the supplier's recommended 3 pumps (6ml) per 100L per dose.

Adjust to your aquarium's plant mass, water chemistry and other fertilisers. Do not assume additional iron is always beneficial.

Pairs perfectly with

  • A suitable complete macro- and micronutrient fertilising programme.
  • Healthy aquatic plants and consistent aquarium lighting.
  • Regular water changes and, where appropriate, CO2 supplementation.
NTA Insight: If your plants are pale or yellowing, check the overall setup before increasing iron. Light, CO2, nitrogen, other nutrients and new-growth patterns matter too. Add iron deliberately as part of a balanced routine rather than dosing blindly.

FAQ

Is LCA Iron (DTPA) a complete plant fertiliser?

No. It is a targeted iron supplement. Most planted aquariums also require other nutrients supplied by a suitable fertilising programme.

Can I use it in a low-light planted tank?

Yes, but demand is typically lower. The supplier recommends the standard dose once or twice a week for low-light setups.

How much is one pump?

The manufacturer's dosing instructions specify 2ml per pump.

Will extra iron fix yellow leaves?

Not necessarily. Yellowing may reflect deficiencies or issues unrelated to iron. Review plant growth, lighting, CO2 and overall nutrient balance before increasing the dose.

What's the difference between 250ml and 500ml?

They are the same type of iron supplement in different bottle sizes. Choose based on how often you dose and the volume of your planted aquarium.

    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.
