Dennerle Plant System E15, 100 pieces (100 Pcs)

Plant System E15 is an iron fertiliser in tablet form that is suitable for aquatic plants in freshwater aquariums and is available in different sizes. You can use it to supply aquarium plants with immediately effective, bivalent iron and ensure fresh and lush green foliage. It will tackle iron deficiency symptoms such as yellow and glassy leaves, which indicate iron chlorosis, and result in rich green leaves again.

Iron is an extremely important nutrient for aquarium plants. It is needed for the formation of lush green leaves without which the plants cannot carry out photosynthesis. Iron deficiency is immediately visible as pale and yellowish leaves.

Plants can only absorb bivalent iron. Unfortunately, this is not stable in an aquarium, oxidises quickly and get converted to ineffective "brown" or trivalent iron. Since tap water contains practically no iron, your aquarium plants need an external iron source such as the Plant System E15.

These iron tablets are protected by chelates or protective shells. They ensure a slow release effect whereby itro is released slowly to the plants over a longer period of time. E15 is free from phosphate and nitrate and does not promote algae growth. In fact, algae growth is actively suppressed with regular fertilization.

Application and dosage recommendation:

1 E15 tablet per 100 L of aquarium water corresponds to 0.27 mg/L of iron. It is best to use the tablets after a partial water change. The tablet will dissolve within a few days.

Use E15 regularly to maintain iron levels in the optimal rage of 0.05 - 0.2 mg/L.

Our expert Oliver Knott recommends:

Use E15 to maintain a basic iron supply in your aquarium and prevent pale, yellowing or glassy leaves.
