Flourish Iron is a high concentration ferric gluconate supplement (10000 mg/L). Plants can benefit more from Flourish Iron because ferric gluconate is already in the ferrous form, meaning they do not need to expend energy to convert it.

Key Features:

• High concentration iron source (10000 mg/L) for planted aquariums
• Ferric Gluconate Iron
• Ferric gluconate is more suitable for foliar feeding compared to iron-EDTA

Usage Instructions:
Use one capful (5 ml) for every 200 liters (50 US gallons) or as needed to maintain approximately 0.10 mg/L of iron. For smaller doses, please note that each cap thread is approximately 1 ml.
