Seachem Flourish 4L (SKU: 724880-519) is a bulk comprehensive liquid fertiliser for freshwater planted aquariums. It contains a complete array of essential trace elements, vitamins, and minerals, including iron, calcium, magnesium, potassium, and trace minerals. Designed to support overall plant health, Flourish works alongside specific macronutrient supplements to form a complete plant care routine.
Unlike competing fertilisers that can oversupply nitrogen and phosphorus, Flourish focuses on bioavailable micronutrients to prevent algae blooms while feeding plant foliage.
