Product Information

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.

Flourish Iron is great for heavily planted aquariums, and, as it is free from any phosphates or nitrates it won't promote algae growth, keeping your tank looking good.

To check iron levels, we recommend the Seachem Multi Test Iron to offer accurate readings of the iron levels in your aquarium.
