{"product_id":"tropical-ferro-aktiv-30ml","title":"Tropical Ferro-Aktiv Iron Fertiliser for Aquatic Plants 30ml","description":"\u003cp\u003eTropical Ferro-Aktiv 30ml is a liquid iron supplement designed for planted aquariums. Iron is a core building block of chlorophyll — the pigment responsible for healthy green colouration in aquatic plants — and without consistent replenishment, most planted tanks will show signs of deficiency over time. This is a straightforward, targeted solution for keepers who want their aquatic planting to thrive rather than just survive.\u003c\/p\u003e\u003ch3\u003eWhy Iron Matters\u003c\/h3\u003e\u003cp\u003eIron deficiency in aquatic plants typically shows as chlorosis: leaves lose their green colour, turning pale or yellowish while growth slows or stalls. Ferro-Aktiv addresses this directly by providing a reliable source of ferric iron, keeping chlorophyll production on track and supporting strong, visible plant health.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eDose at 10 ml per 100 litres of water. Apply at least once a week, ideally during water changes to maintain consistent iron levels. In heavily planted aquariums with higher demand, smaller doses applied more frequently will deliver better results than a single weekly addition.\u003c\/p\u003e\u003ch3\u003ePack Size\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThis listing is for the 30 ml bottle\u003c\/li\u003e\n\u003cli\u003eAlso available in 500 ml for larger or more heavily planted systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eRegular use of Tropical Ferro-Aktiv keeps aquatic plants in genuinely good condition — vibrant colour, steady growth, and none of the telltale signs of iron-starved leaves.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54146873491793,"sku":"1VTT125","price":2.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/1VTT125_1.jpg?v=1782487044","url":"https:\/\/viperia.co.uk\/products\/tropical-ferro-aktiv-30ml","provider":"Viperia UK","version":"1.0","type":"link"}
