Iron is of crucial importance for all aquarium plants. It is needed for generating the all-important chlorophyll. Without chlorophyll, the plant cannot photosynthesize. The effects of iron deficiency are immediately apparent: the young leaves appear pale and yellowish (iron-induced chlorosis). Please note: plants can only absorb divalent -white- iron. This is unfortunately not stable in an aquarium, and is quickly oxidised to become ineffective trivalent -brown- iron. Tap water contains virtually no iron. Aquarium plants are therefore reliant upon regular iron fertilization. Dennerle Perfect Plant E15 FerActiv iron fertilizer provides all aquarium plants with divalent nutrient iron that they can use immediately, thereby ensuring a beautiful, fresh green colour. Symptoms of deficiency such as yellow, glassy leaves are thereby virtually completely cured, while young leaves can once again display a rich, green colour. Deficiency symptoms such as yellow, glassy leaves are largely cured, and young leaves display a rich green colouring once again. Other vital nutrients such as potassium and manganese strengthen the plants and establish ideal conditions for powerful and lush growth. Dennerle E15 nutrient iron is protected from oxidation by highly effective shells -so-called chelates- which maintain it in plant-available form over a prolonged period (depot effect). Dennerle E15 is of course, phosphate- and nitrate-free and thus does not promote algae growth.
