Plant System E15

Iron fertilizer for large, demanding plant aquaria

• Nutrient iron for large and heavily planted aquaria
• With 2-valent, directly plant-available nutrient iron
• For lush green leaves and intense colors
• Immediate and long-term effect
• High reach due to highly concentrated ingredients
• Optimized effect in the Plant System in combination with V30 and S7

As the size of the aquarium increases, so does the quantity and size of the plants. For this reason we have developed our plant 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 aquaria. All macro- and micronutrients as well as trace elements are covered. Plant System E15 iron fertilizer provides all aquarium plants with divalent nutrient iron II that they can use immediately, thereby ensuring a beautiful, fresh green color. Iron is of central importance for all aquarium plants. It is needed for the formation of the vital leaf green. Without leaf green, the plant cannot carry out photosynthesis. Iron deficiency shows up immediately: the 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 trivalent, "brown" iron. Tap water contains practically no iron. Aquarium plants are therefore dependent on regular iron fertilization. Special protective shells – so-called chelates – provide the E15 iron with effective protection and ensure its long-term availability to plants in the aquarium (depot effect). E15 is phosphate- and nitrate-free and thus does not promote algae growth. Special Note: Commercial iron tests often fail to detect chelated iron. These tests then indicate inadequate results, although there is actually enough iron in the aquarium water.
