Brightwell – Florin-Fe – Iron Supplement for Planted Aquariums (250ml)

Product details

Brightwell – Florin-Fe – Iron Supplement for Planted Aquariums (250ml) is an iron additive designed to supply plants with bioavailable ferrous (Fe2+) and ferric (Fe3+) iron. In planted aquariums, iron is a micronutrient that supports chlorophyll production and plant metabolic reactions. It’s used to help prevent or correct iron deficiency symptoms (such as yellowing or translucent leaves) and to maintain a usable iron level for steady growth rather than a one-time spike.

Features:

• Supplies both ferrous (Fe2+) and ferric (Fe3+) iron
• Formulated to deliver iron in immediate and delayed stages for more stable availability
• Supports chlorophyll production and important enzyme activity for plant metabolism
• Helps reduce the risk of yellow or transparent foliage associated with iron deficiency
• Contains iron from a concentrated source intended for planted aquarium nutrient systems
• Shake well before dosing to ensure consistent distribution
