DENNERLE - Plant System E15, 40 Tabs - Iron-based fertilizer for aquariums

Iron fertilizer from the Dennerle Plant System Set

As the size of the aquarium increases, the quantity and size of plants also increases. This is why we developed our herbal system, a system with highly concentrated components. The components of Plant System V30 (complete fertilizer), Plant System S7 (vital substances) and Plant System E15 (iron fertilizer) are therefore developed to meet the needs of large aquariums. All macro and micronutrients as well as trace elements are covered.

E15 plant system iron fertilizer provides all aquarium plants with divalent nutrient iron II that they can use immediately, ensuring a beautiful fresh green color. Iron is of paramount importance for all aquarium plants. It is necessary for the formation of vital green leaves. Without a green leaf, the plant cannot carry out photosynthesis. Iron deficiency manifests itself immediately: young leaves appear pale and yellowish (iron chlorosis).

Important to know: Plants can only absorb so-called bivalent iron. Unfortunately, this is not stable in the aquarium, but is quickly oxidized and thus converted to ineffective "brown" trivalent iron. Tap water contains almost no iron. Aquarium plants therefore depend on regular fertilization with iron.iron with effective protection and ensuring its long-term availability for the aquarium plants (deposition effect). E15 is phosphate and nitrate free and therefore does not promote the growth of algae. Special Note: Commercial iron tests often fail to detect chelated iron. These tests then indicate insufficient results, although there is in fact sufficient iron in the aquarium water.

Application

Simply add tablets to aquarium water, ideally after replacing some of the water. They dissolve slowly over a few days.

Dosage

1 tablet per 100 L (26.4 US gal) adds 0.27 mg/l (ppm) iron to aquarium water. Regular use results in iron content in the optimal range of 0.05 to 0.2 mg/l (ppm).
