Seachem Flourish Excel 500 ml – Bioavailable Carbon for Aquarium Plants

Boost aquarium plant health with a convenient carbon source

Flourish Excel delivers a readily available source of bioavailable organic carbon, designed to support lush plant growth in freshwater tanks. Backed by Seachem’s science-driven approach and built from hobbyist expertise, this product aims to harmonize plant needs with easy, reliable dosing. The formula also features iron-reducing properties, helping iron stay in a form that plants can more easily utilize, which can contribute to stronger, greener foliage in a variety of setups.

In addition to carbon delivery, Flourish Excel is formulated to support photosynthesis by introducing finished carbon compounds that plants can readily use. This means your stems may appear healthier and more vibrant as the plants photosynthesize with the added carbon. While individual results vary, many hobbyists report noticeable improvements in growth and coloration when used as part of a balanced tank routine.
