The iron fertilizer from the Dennerle Plant System Set
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.
Application
Simply add tablets to the aquarium water, ideally after replacing part of the water. They will dissolve slowly over a few days.
Dosage
1 tablet per 100 L (26.4 US gal) adds 0.27 mg/l (ppm) iron to the aquarium water. Regular use results in an iron content in the optimum range of 0.05 – 0.2 mg/l (ppm).
The Dennerle Level System
With the level system you can find the right fertilizer quickly and easily.
Level 1 = For planted aquariums of type 1 with simple and few plants.
Level 2 = For heavily planted aquariums:
- of type 2 with many and demanding plants
- Type 3 from a size of 100 L with demanding plants
Add-Ons = optional care products to improve growth and health suitable for all aquarium types
Type 3 aquaria
The fertilizer set was specially developed for heavily planted community aquariums. This type of aquarium is characterized by a planting of approx. 70 – 80 % of the bottom surface, approx. half of which are fast-growing species and good growing conditions (good lighting, CO2 supply).
