Iron - The key to the health of aquatic plants.
Iron is essential for all aquatic plants, necessary for the formation of an element as vital as chlorophyll.
Without chlorophyll in plants can not be completed because the process of photosynthesis.
The symptoms of iron deficiency appear immediately, especially the young leaves at the apex of shoots, yellowing and lose consistency (ferric chlorosis).
Important: the plants can absorb only so-called iron "white" bivalent.
Unfortunately this type of iron in the aquarium is not stable, but easily oxidized iron in so doing become "dark" trivalent, whose effectiveness is zero.
As tap water, it has an iron content close to zero.
The life of aquatic plants was based on a regular fertilization to provide them the iron they need.
E15 FerActiv of Dennerle:
iron "white" that gives the leaves a beautiful deep green.
The iron-based fertilizer E15 FerActiv all aquatic plants provide a nutrient-based bivalent iron to immediate action that will make wonderful and fresh green leaves, taking care of the whole deficiency symptoms which may be yellowing and loss of texture of the leaves, and allowing the young leaves to regain their deep green.
Other nutrients of vital importance, as eg potassium and manganese strengthen the plants and create the best conditions for robust growth and flourishing.
The feeding iron-based E15 is protected against oxidation by a substance extremely effective - the so-called chelates - and remains so for a long time available to the plants within the aquarium (depot effect).
Of course the E15 is devoid of phosphate and nitrate and thus stimulate the growth of algae.
