FAQ: Why do I need to use Seachem Flourish Iron™ if I’m already using Flourish®?

Iron is an important nutrient in the planted aquarium. In order to maintain an adequate iron concentration it should be dosed on a fairly regular basis (daily). Flourish® should be dosed less often (semi-weekly or weekly) since its components are not rapidly depleted. Daily dosing with Flourish can lead to unwanted algae growth. By having these supplements as separate products, the hobbyist can add Flourish Iron™ every day and not risk unwanted algae growth while still adding the necessary level of Flourish® on a less regular basis.
