    🌟 Why You'll Love It

    Enhances vibrant plant coloration Iron plays a key role in developing rich green foliage and deep red tones in aquarium plants.

    Essential for chlorophyll production Iron supports chlorophyll synthesis, allowing plants to maintain strong photosynthesis and healthy leaf development.

    Supports faster plant growth Healthy iron levels help plants grow stronger stems and produce new leaves more efficiently.

    Corrects common iron deficiency symptoms

    Yellowing between leaf veins on new leaves
    The leaf tissue becomes pale or yellow while the veins remain darker green.

    Pale or faded leaf coloration
    Leaves may lose their rich green color and appear washed out or light green.

    Loss of red or orange tones in colored plants
    Plants that normally display strong red or orange hues may develop dull, brownish, or green leaves instead.

    Slow or weak new growth
    Plants may produce smaller leaves, thinner stems, or slower overall growth.

    Ideal for colorful and demanding plants  Especially beneficial for plants such as Rotala ‘Red Blood', Rotala ‘Orange Juice’, Alternanthera reineckii, Ludwigia Repens ‘Rubin’, Ludwigia Repens, and large plants like Amazon Sword.

    🔥 Application Guide

    Ensure your aquarium substrate is at least 5–7 cm (2–3 inches) deep before inserting capsules.

    Push each capsule about 2–3 cm (1 inch) below the substrate, placing it slightly near plant roots rather than directly under the stem base. Avoid leaving capsules exposed on the substrate surface.

    Dosage Guide

    Up to 10 gal — 1 capsule (light planting) / 2 capsules (heavy planting or red plants)

    10–20 gal — 2 capsules / 3–5 capsules

    20–40 gal — 3–5 capsules / 6–8 capsules

    40–75 gal — 6–8 capsules / 10–12 capsules

    75+ gal — 10–12 capsules / 15–18 capsules (spread evenly)

    💡 Tip: Red plants such as Rotala ‘Red Blood', Rotala ‘Orange Juice’, Alternanthera reineckii, Ludwigia Repens ‘Rubin’, Ludwigia Repens, and large plants like Amazon Sword may benefit from slightly higher iron levels.

    ⚠️ Safety Tip: Insert capsules fully under the substrate and avoid breaking them in the water column.

    ⚠️ Overdose Notice: Excess iron can contribute to algae growth. Start with a lower dosage and increase gradually based on plant response.

    Why Iron Deficiency Appears on New Leaves
    Iron is an immobile nutrient inside plant tissues, meaning plants cannot move it from older leaves to new growth. As a result, iron deficiency usually appears first on new leaves, which may develop pale coloration or yellowing between veins.

    Why HEDTA Iron Works Well in Aquariums
    In aquariums, iron can quickly become unavailable when it reacts with oxygen and minerals in the water. HEDTA stabilizes the iron and helps keep it dissolved and accessible for plant uptake in typical planted aquarium pH ranges (works up to pH 8).

    Aquarium Safe When capsules are inserted under the substrate and used according to the recommended dosage, they are safe for freshwater aquariums with fish, shrimp, snails, and other aquatic life.
