Here is a direct quote from my ADA Product English Manual:
"Plant color-loss is a commonly observed problem in planted aquariums. In most of the cases, this is caused by deficiency of iron in the aquarium water. ECA. rich in iron in a form which does not easily combine with other ions, prevents color-loss and improves the condition of aquatic plants. Also contains various natural organic acids."
If this product sounds like a gimmick, then Flourish must be snake oil. It sounds pretty reasonable to me.
