Dennerle Plant System E15

Dennerle Plant System E15 – Targeted Iron Supply for Healthy Aquarium Plants

Dennerle Plant System E15 is a specialised iron fertilizer developed to correct and prevent iron deficiency in freshwater aquarium plants. Iron is a vital micronutrient required for chlorophyll formation and energy transfer during photosynthesis. When iron levels are insufficient, plants often develop pale or yellow leaves, especially in new growth.

The tablet-based format releases nutrients gradually, ensuring stable iron availability over an extended period. This controlled release reduces nutrient fluctuations and minimises the risk of algae growth, making E15 suitable for both low-tech and high-tech planted aquariums.
