Create a natural blackwater look with tannins designed for freshwater biotope aquariums.

Quick Facts

  • Brand: Liverpool Creek Aquariums (LCA)
  • Type: Liquid tannin and water-softening treatment
  • Suitable for: Freshwater blackwater and South American-style biotopes
  • Available sizes: 250ml and 500ml
  • Effect: Adds a natural tea-coloured tint and may influence water softness and acidity

Is this for you?

✔️ Perfect if:

  • You want a natural tannin-tinted aquarium appearance.
  • You keep freshwater species suited to tannin-rich, softer, more acidic conditions.
  • You are building a South American-inspired blackwater biotope.

❌ Avoid if:

  • You need to maintain hard, alkaline water for species that prefer those conditions.
  • You want completely clear aquarium water without a brown tint.
  • You cannot monitor pH and hardness when changing water chemistry.

Why choose LCA Tannin Plus?

LCA Tannin Plus combines a specialised tannin blend with a water-softening component. It is designed to help recreate the appearance of tannin-rich tropical habitats. The manufacturer also describes a calcium de-ioniser in the formula; actual changes in your aquarium depend on your starting water parameters.

Benefits

  • Creates a natural tea-coloured, blackwater-style appearance.
  • Useful for designing South American-inspired freshwater habitats.
  • Combines tannins with a water-softening component.
  • Available in two sizes for different aquarium requirements.

Using Tannin Plus safely

  • Follow the current manufacturer's label for the correct dose for your aquarium's actual water volume.
  • Add gradually in an area with good circulation.
  • Measure pH, GH and KH before and after treatment, particularly in aquariums with sensitive livestock.
  • Expect some brown or tea-coloured tint; the colour may gradually fade.
  • Avoid abrupt water-parameter changes and do not exceed label instructions.

No exact pump dosage is stated here because it should be checked against the bottle label before publishing a numerical recommendation.

Pairs perfectly with

  • Natural driftwood and botanicals for a blackwater-style aquarium.
  • Suitable leaf litter and aquarium-safe hardscape.
  • Reliable pH, GH and KH testing.
NTA Insight: A darker-looking tank is not automatically a softer or safer tank. Test your actual water parameters, especially KH and pH, and match them to the needs of your fish. Introduce changes gradually instead of chasing a particular water colour.

FAQ

Will Tannin Plus turn the water brown?

Yes. Tannins give aquarium water a natural amber or tea-coloured tint, which gradually fades over time.

Does it lower pH or soften water?

LCA markets the product as including a water-softening agent and as supporting more acidic biotope conditions. The actual effect depends on your source water, buffering capacity and dose, so test before and after use.

Is it suitable for every freshwater aquarium?

No. It is best suited to aquariums whose fish and plants are compatible with tannin-rich conditions. It is not the right choice for every hard-water setup.

Can I use it for a South American biotope?

Yes. Recreating tannin-rich South American freshwater habitats is one of the manufacturer's stated uses.

How much should I dose?

Use the amount stated on your bottle's current label for your actual water volume. Monitor water chemistry, and avoid sudden changes.

    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.
