Support healthy aquatic plant growth with Dr. Tank Iron Sticks. As part of the Dr. Tank Plant Nutrition Series, these slow-release substrate sticks provide iron (Fe), an essential micronutrient that supports chlorophyll production and photosynthesis. Healthy iron levels help aquatic plants efficiently use available light, supporting faster growth, resilience and vibrant foliage.
Iron Sticks are ideal for planted aquariums using sand or gravel, or for aquariums that would benefit from additional iron supplementation. While iron plays an important role in plant health, it works best as part of a balanced fertilization routine and should not be the sole source of plant nutrition.
