Containing 10,000 mg\/L of ferrous iron (iron gluconate), Flourish Iron provides iron in a form that is immediately available for plant uptake, helping to support lush green growth, vibrant colouration, and healthy new leaves.\u003c\/p\u003e\n\u003cp\u003eIron is an essential nutrient for aquatic plants and plays a vital role in chlorophyll production. Because plants cannot move iron from older leaves to new growth, deficiencies first appear as yellowing (chlorosis) of young leaves, pale new growth, and weak, slender stems. Seachem Flourish Iron quickly replenishes available iron, helping your plants maintain rich colour and vigorous growth. Unlike many iron supplements that use ferric iron (Fe³⁺), Flourish Iron contains ferrous gluconate (Fe²⁺), a more readily absorbed form that requires less energy for plants to utilise.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHighly concentrated 10,000 mg\/L iron supplement\u003c\/li\u003e\n\u003cli\u003eProvides iron in the highly bioavailable ferrous (Fe²⁺) form\u003c\/li\u003e\n\u003cli\u003eSupports healthy chlorophyll production\u003c\/li\u003e\n\u003cli\u003eHelps prevent yellowing (chlorosis) of new leaves\u003c\/li\u003e\n\u003cli\u003eEncourages stronger stems and vibrant plant growth\u003c\/li\u003e\n\u003cli\u003eFree from phosphate and nitrate\u003c\/li\u003e\n\u003cli\u003eSuitable for all freshwater planted aquariums\u003c\/li\u003e\n\u003cli\u003eIdeal alongside Seachem Flourish®, Flourish Excel®, and other Seachem plant supplements\u003c\/li\u003e\n\u003cli\u003eAvailable sizes - 100mL, 500mL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDirections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eDose 5ml per 200 litres (50 US gallons), or as required to maintain approximately 0.10 mg\/L of iron.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFor smaller aquariums, each cap thread holds approximately 1ml for accurate dosing.\u003cbr\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Creature Culture","offers":[{"title":"100ml","offer_id":52523997856055,"sku":null,"price":17.09,"currency_code":"NZD","in_stock":false},{"title":"500ml","offer_id":52523997888823,"sku":null,"price":35.99,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/2415\/7239\/files\/ChatGPTImageJun26_2026_02_46_03PM.png?v=1782442388","url":"https:\/\/creatureculture.co.nz\/products\/seachem-flourish-iron-iron-supplement-for-planted-aquariums-100ml-amp-500ml","provider":"Creature Culture","version":"1.0","type":"link"}
