Iron is a vital element in a planted aquarium. Seachem Flourish Iron is a concentrated supplement of iron and gluconate that will boost iron levels for healthy plants that glow with health. Look out for yellowing plants, with thin leaves. This is a sign of an iron deficiency and left untreated can cause severe plant loss.
