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.

"I had Malaysian trumpet snails take over my 125 gallon tank years ago. Through pure chance I found this product while browsing through the site and thought why not? In 3 days the snails are gone. I am so excited to do a rescape now that those pesky snails aren’t around making the tank look bad! Definitely recommend! Oh yea, I have fish including scales fish as well as neocaridina shrimp and they are all still a living and appear to be doing well."
