If your aquatic plants are developing pale or yellowing leaves, a lack of available iron is a likely cause — this product addresses that directly.\u003c\/p\u003e\u003ch3\u003eWhy Iron Matters in a Planted Aquarium\u003c\/h3\u003e\u003cp\u003eIron is an essential component of chlorophyll, the pigment responsible for healthy green colouration in aquatic plants. Without a consistent supply, plants suffer from chlorosis — leaves lose their colour, growth slows, and the overall condition of the planting declines. Ferro-Aktiv provides iron in a form aquatic plants can readily absorb, supporting vigorous and visually healthy growth.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eAdd Ferro-Aktiv to your aquarium at least once a week, ideally during water changes. In heavily planted setups where iron demand is higher, smaller doses applied more frequently will deliver more consistent results. The recommended dosage is 10 ml per 100 litres of water.\u003c\/p\u003e\u003ch3\u003eSizes Available\u003c\/h3\u003e\u003cp\u003eFerro-Aktiv is available in two sizes to suit aquariums of different scale and planting density. Whether you have a single display tank or are maintaining multiple planted setups, there is an option suited to your requirements — select your preferred size from the variants listed on this page.\u003c\/p\u003e\u003cp\u003eConsistent iron supplementation is one of the most straightforward ways to maintain the quality of a planted aquarium. Regular use of Ferro-Aktiv keeps foliage richly coloured and supports steady, healthy plant development over time.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"30ml","offer_id":54176463061329,"sku":"1VTT125","price":2.33,"currency_code":"GBP","in_stock":false},{"title":"500ml","offer_id":54176463094097,"sku":"1VTT130","price":16.99,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/viperia.co.uk\/products\/tropical-ferro-aktiv","provider":"Viperia UK","version":"1.0","type":"link"}
