As the size of the aquarium increases, so do the number and size of the plants. The products Plant System V30 (complete fertilizer), Plant System S7 (vitamins and vital substances), and Plant System E15 (iron fertilizer) are designed to meet the needs of large aquariums. They provide all macro- and microelements as well as essential nutrients.

Plant System E15 supplies all aquarium plants with immediately effective bivalent iron and ensures a fresh, rich green color.

Iron is of crucial importance for all aquarium plants. It is necessary for the formation of vital chlorophyll. Without chlorophyll, plants cannot carry out photosynthesis. Iron deficiency is immediately noticeable: young leaves become pale and yellowish.

Special protective compounds – so-called chelates – effectively protect the iron in E15 and keep it available to plants in the aquarium for a long period.

E15 does not contain phosphates or nitrates and does not promote algae growth.

Application:
Simply add the tablets to the aquarium, preferably after a partial water change. They dissolve slowly over several days.

Dosage:
1 tablet per 100 liters of aquarium water.
With regular use, the iron level is maintained within the optimal range of 0.05–0.2 mg/L.
